CROSS REFERENCE TO RELATED APPLICATION

[0001] The present application claims priority to U.S. Patent Application No. 14/815,407, filed on July 31, 2015 and entitled "Methods and systems for clustering of repair orders based on alternative repair indicators," which is hereby incorporated by reference in its entirety.

INCORPORATION BY REFERENCE

[0002] U.S. Patent Application No. 14/270,994, filed on May 6, 2014, is incorporated herein by reference, as if fully set forth in this description.

BACKGROUND

[0003] Many products produced by manufacturers occasionally have to be repaired. Many- owners are unequipped or otherwise unable to repair certain products. Such owners may depend on professional repair technicians to service or repair the owner's product.

[0004] The repair technicians typically repair products at a product repair shop. A repair shop has traditionally produced a repair order (RO) to capture a variety of information regarding a request for servicing or repairing a product. As an example, the captured information can include information identifying the product, the product's owner, the repair shop, the date of repair, and the type of repair or service needed or performed. The RO can exist in various formats such as a paper format or an electronic format.

[0005] Product manufacturers use a significant amount of resources (e.g., human and financial) to generate repair information, such as repair manuals and technical sendee bulletins, that repair technicians can reference while diagnosing and repairing a product. It may be beneficial to product manufacturers if the repair information can be generated automatically by a computer-readable device. It may be beneficial to product manufacturers and repair technicians if the repair information provided to the repair technicians is automatically generated based on RO information,

OVERVIEW

[0006] Example implementations are described herein. In one aspect, a method is disclosed. The method involves determining, by at least one processor, that a particular computer-readable vehicle repair order (RO) corresponds to an existing cluster of computer- readable vehicle repair orders (ROs) due to the particular RO including data that refers to a particular vehicle symptom, where the existing cluster is arranged to contain ROs that correspond to the particular vehicle symptom. The method also involves, in response to determining that the particular RO corresponds to the existing cluster, the at least one processor determining that the particular RO includes data indicating an alternative repair that defines a vehicle repair for resolving the particular vehicle symptom other than by replacement of a particular vehicle component.

I. INTRODUCTION

[0021] This description describes several example embodiments including example embodiments regarding alternative repairs. At least some of the example embodiments include, but are not limited to include, one or more of the following features: determining that a particular computer-readable vehicle repair order (RO) corresponds to an existing cluster of ROs that is arranged to contain ROs that correspond to the particular vehicle symptom, determining that the particular RO includes data indicating an alternative repair, and adding the particular RO to a different cluster of ROs arranged to contain ROs that correspond to the particular vehicle symptom and to the alternative repair.

[0022] A vehicle repair tool can include any of a variety of repair tools a repair technician, a product owner, a person working at a repair shop, or some other person can use to repair a vehicle. Repairing a vehicle can include, but is not limited to include, diagnosing a vehicle, servicing a vehicle, performing maintenance (e.g., preventive maintenance) on a vehicle, or verifying a repair performed on a vehicle to correct a vehicle malfunction. Accordingly, a vehicle repair tool can be referred to as one or more of the following terms: a vehicle diagnostic tool, a vehicle service tool, a vehicle maintenance tool, and a vehicle repair verification tool, or more generally, a machine.

[0023] A vehicle is a mobile machine that may be used to transport a person, people, or cargo. As an example, any vehicle described herein may be driven or otherwise guided along a path (e.g., a paved road or otherwise) on land, in water, or in the air or outer space. As another example, any vehicle described herein may be wheeled, tracked, railed or skied. As yet another example, any vehicle described herein may include an automobile, a motorcycle, a light-duty truck, a medium-duty truck, a heavy-duty truck, a semi-tractor, or a farm machine. As still yet another example, any vehicle described herein may include or use any appropriate voltage or current source, such as a battery, an alternator, a fuel ceil, and the like, providing any appropriate current or voltage, such as about 12 volts, about 42 volts, and the like. As still yet another example, any of the vehicles described herein may include or use any desired system or engine. Those systems or engines may include items that use fossil fuels, such as gasoline, natural gas, propane, and the like, electricity, such as that generated by a battery, magneto, fuel cell, solar cell and the like, wind and hybrids or combinations tiiereof. As still yet another example, any vehicle described herein may include an electronic control unit (ECU), a data link connector (DLC), and a vehicle communication link that connects the DLC to the ECU.

[ΘΘ24] Although many of the example embodiments are described with respect to a vehicle, the example embodiments can be applicable to products or repairable items other than a vehicle. As an example, the other products or repairable items can include home appliances, such as a refrigerator, a dishwasher, or a washing machine, or a consumer electronic device, such as a television, a cellular phone, or a tablet device. Other examples of the other products or repairable items are also possible. Accordingly, for embodiments based on these other products or repairable items, the term, vehicle in the described embodiments can be replaced with a name of the other product or repairable item.

[0025] In this description, the articles "a ^" ' or "an" are used to introduce elements of the example embodiments. Any reference to '"a" or "an" refers to "at least one," and any reference to "the" refers to "the at least one," unless otherwise specified, or unless the context clearly dictates otherwise. The intent of using those articles is that there is one or more of the elements. The intent of using the conjunction "or" within a described list of at least two terms is to indicate any of the listed terms or any combination of the listed terms. The use of ordinal numbers such as "first," "second," "third" and so on is to distinguish respective elements rather than to denote a particular order of those elements. For purpose of this description, the terms "multiple" and "a plurality of refer to "two or more" or "more than one."

[0026] The block diagram(s) and flow chart(s) shown in the figures are provided merely as examples and are not intended to be limiting. Many of the elements illustrated in the figures or described herein are functional elements that can be implemented as discrete or distributed elements or in conjunction with other elements, and in any suitable combination and location. Those skilled in the art will appreciate that other arrangements and elements (e.g., machines, interfaces, functions, orders, or groupings of functions) can be used instead. Furthermore, various functions described as being performed by one or more elements or a machine described herein can be carried out by a processor executing computer-readable program instructions or by any combination of hardware, firmw are, or software.

II. EXAMPLE ARCHITECTURE

[0027] FIG. 1 is a block diagram of a system 100 in accordance with one or more example embodiments. Various combinations of the elements shown in FIG. 1 can be arranged as other systems or as a sub-system to carry out example embodiments described herein. System 100 includes a vehicle repair data (VRD) system 102 and a network 104. Network 104 can include a wide area network (WAN), such as the Internet or a portion thereof. Additionally or alternatively, network 104 can include a wireless network, a wired network, a local area network (LAN), or some other type of network. Network 104 can include two or more of the aforementioned example networks.

[0028] System 100 includes a vehicle repair tool (VRT) 106, and VRT 108, 110, 112, 114, 1 16, 118, and 120. Each VRT or a combination of multiple VRT can include or be arranged as a machine. Any VRT described herein can be, but is not required to be, configured to generate or transmit an original repair order (RO) to VRD system 102. An RO generated by a VRT can be provided to an operator of VRD system 102 by a courier 122, such as the United States Postal Sen-ice or the Federal Express Corporation. The operator of VRD system 102 can enter an original RO into VRD system 102 using an RO manual entry device, such as an RO manual entry device 202 shown in FIG. 2. The manually-entered RO can be stored in a data storage device, such as a data storage device 2.10 shown in FIG. 2.

[0029] VRT 114, 1 16, 118, and 120 represent vehicle repair tools that are configured to perform at least one of the following functions: request a repair-hint (e.g., an auto-generated repair hint) stored at VRD system 102, receive a repair-hint transmitted from VRD system 102 using network 104 or otherwise provided or generated by VRD system 102, and present a repair-hint by a user interface. A repair-hint generated by VRD system 102 can be provided to an operator of a VRT, such as VRT 114, by courier 122. As an example, courier 122 can provide the repair-hint by providing the VRT operator with a computer-readable medium, such as a CD-ROM, including a repair-hint generated by VRD system 102. VRT 1 16, 118, and 120 can receive a repair-hint generated by VRD system 102 and transmitted to the VRT usmg wireless or wired communications and network 104.

[0030] A VRT can include a code reader, such as a one-dimensional bar code reader or a two-dimensional bar coder reader. The code reader cars read and decode a code on a vehicle, such as a VIN bar code, a code on a replacement part, such as a bar code or quick-response code on packaging of a replacement part, or some other type of code. Data encoded from a code can be entered onto an original RO, such as original RO 400 shown in FIG. 4.

[0031] Next, F G 2 is a block diagram showing details of a vehicle repair data (VRD) system 200. VRD system 102, shown in FIG. 1, can be configured similar to VRD system 200. VRD system 200 can be configured like VRD system 102 shown in FIG. 1. VRD system 200 can include or be arranged as a machine. VRD 200 or one or more components tiiereof can be arranged or referred to as a computing system. VRD system 200 can comprise, be configured as, or be referred to as a server system, a server device, or more simply, a server. In accordance with embodiments in which VRD system. 2.00 operates as a server, VRD system 200 can serve one or more vehicle repair tools (VRT) operating as a client device to the server.

[0032] VRD system 200 includes the RO manual entry device 202, a processor 204, a user interface 206, a network interface 208, and a data storage device 210, all of which can be linked together via a system bus, network, or other connection mechanism 212.

[0033] RO manual entry device 202 can include one or more devices for inputting data shown on a printed RO into VRD system 200 for storage as an original RO within repair orders (RO) 214. As an example, RO manual entry device 202 can include a scanner device with or without an optical character recognition software application. As another example, RO manual entry device 202 can include a keyboard for keying in (e.g., typing) the data shown on the printed RO and sending the keyed in (e.g., typed or otherwise entered) data to processor 204 for storage as an original RO within RO 214. As yet another example, RO manual entr - device 202 can include a device that accepts data storage devices, such as a CD- ROM including data representing an original RO generated by a VRT. As yet another example, RO manual entry device 202 can include a laptop or desktop computing device with or connected to a display.

[0034] An original RO can be displayed by RO manual entry device 202 or user interface 206. For any of a variety of reasons, such as security of information located on an original RO, VRD system 102 can be configured such that an original RO generated by a first VRT, such as VRT 106, is not provided to a second VRT, such as VRT 116. VRD system 1 2 can generate a presentable RO based, at least in part, on information on the original RO generated by the VRT 106, and provide the presentable RO to VRT 116.

[0035] A processor, such as processor 204, can include one or more general purpose processors (e.g., INTEL single core microprocessors or INTEL multicore microprocessors) or one or more special purpose processors (e.g., digital signal processors). A processor, such as processor 204, can be configured to execute computer-readable program instructions, such as computer-readable program instractions (CRPI) 218. For purposes of this description, processor 204 executing CRPI 218 to perform some function described herein can include executing a portion of CRPI 218 or the entirety of CRPI 218. Executing a portion or the entirety of CRPI 218 can include executing some of the computer-readable program instructions multiple times. Processor 204 can be programmed to perform any one or any combination of functions performed by execution of a program instruction of CRPI 218.

[0036] User interface 206 can include an interface to components operable to enter data or information into VRD system 200 or to components that can present data or information output by VRD system 200. Those components can be referred to as user interface components. User interface 206 can include one or more audio/visual ports or communication ports that connect to a user interface component by a wired or wireless user interface communication link.

[0037] User interface 206 can include one or more of the user interface components. As an example, the user interface components can include an infrared remote control device, a display device, a loud speaker configured to convert electrical signals to audible sounds, a keyboard, a touch screen, a pointing device, such as a computer mouse, or some other component for generating signals to enter data or information into VRD system 200 or to present data or information output by user interface 206.

[0038] User interface 206 can include a transmitter or transceiver to provide the data or information to another user interface component or to another element of VRD system 200. The data or information provided by user interface 206 can include, but is not limited to include, a repair-hint of repair-hints 220.

Θ039] Network interface 208 can include an interface to one or more communication networks, such as network 104. For use with wireless communication networks, network interface 208 can include one or more antennas for transmitting or receiving wireless communications. Network interface 208 can include one or more communication ports configured to connect to a wired communication link of a network, such as a coaxial cable, an Ethernet cable, a fiber optic cable, a digital subscriber line (DSL), a telephone line of a public switched telephone network (PSTN) or some other wired connector. Network interface 208 can include a network controller including a transmitter, a receiver, or a transceiver. The transmitter or transceiver can provide data or information to a communication port for transmission as network communications over the connected network. The receiver or transceiver can receive data or information received at a communication port from the connected network.

[0040] A data storage device, such as such as data storage device 210 or any other data storage device discussed in this description or included within a device or system described in this description, may include a non-transitory computer-readable medium, a transitory computer-readable medium, or both a non-transitory computer-readable medium and a transitory computer-readable medium. In one respect, a non-transitory computer-readable medium may be integrated in whole or in part with a processor. In another respect, a non- transitory computer-readable medium, or a portion thereof, may be separate and distinct from a processor.

[0041] A non-transitory computer-readable medium may include, for example, a volatile or non-volatile storage component, such as an optical, magnetic, organic or other memory or disc storage. Additionally or alternatively, a non-transitory computer-readable medium may include, for example, a random-access memory (RAM), a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), a compact disk read-only memory (CD-ROM), or another memory device that is configured to provide data or CRPI to a processor.

[0042] A transitory computer-readable medium may include, for example, CRPI provided over a communication link, such as a communication link which is connected to or is part of the network 104. The communication link may include a digital or analog communication link. The communication link may include a wired communication link or a wireless communication link.

[0043] A computer-readable medium may be referred to by other terms such as a "computer-readable storage medium," a "data, storage device," a "memory device," a "memory," or a "computer-readable database." Any of those alternative terms may be preceded with the prefix "transitory" or "non-transitory."

[0044] Data storage device 210 can store a variety of data. The data stored by data storage device 210 can be data that was provided to data storage device 210 for storage from RO manual entry device 202, processor 204, user interface 206 or network interface 208. As shown in FIG. 2, data storage device 210 can store repair orders (RO) 214, a taxonomy term database 216, computer-readable program instructions (CRP1) 218, repair hints 220, metadata 222, vehicle leverage data 224, parts leverage data 226, text strings 228, and search terms 230. Search terms 230 can include, but is not limited to, vehicle-identification (i.e., vehicle-ID) search terms 232, such as year/rnake/model/engine (Υ/Μ/Μ/Έ) attributes, and symptom criterion 234.

[0045] RO 214 can include computer-readable RO. The computer-readable RO can be arranged as a structured query language (SQL) file, an extensible markup language (XML) file, or some other type of computer-readable file or data stracture. The RO within RO 214 can be received from RO manual entry device 202, from network interface 208 by way of network 104, or from another device. The RO within RO 214 can be an original RO, such as RO generated by a VRT shown in FIG. 1 or entered using RO manual entry device 202, or a presentable RO generated by VRD system 200.

[0046] FIG. 4 shows an example original RO 400. Original RO 400 can be generated by a VRT, such as any VRT shown in FIG. 1. Original RO 400 can include a computer-readable- data RO (or more simply, computer-readable RO) transmitted over network 104. Original RO 400 can include a paper-copy RO, such as carbonless multi-sheet RO or some other type of paper-copy RO. Original RO 400 can include both a computer-readable-data version and a paper-copy version. A paper-copy RO can be generated without using a VRT. A computer- readable RO generated from a paper-copy RO can be an original RO.

[0047] Original RO 400 includes a service provider identifier 402, a date of service identifier 404, a customer indicator 406 that indicates a customer seeking service of a given vehicle, vehicle information 408 that indicates the given vehicle, vehicle service requests 410, 412, and 414 indicating the complaint(s) or service(s) requested by the customer, parts information 416 indicating parts obtained for sen/icing the given vehicle, service procedure information 418, 420, and 422 carried out on the given vehicle, and a vehicle-usage indicator 430 (e.g., vehicle mileage data that indicates a number of miles the given vehicle has been driven). The vehicle-usage indicator 430 on original RO 400 can indicate a driven distance using kilometers or some other units as an alternative or in addition to vehicle mileage data. In addition to or as an alternative to indicating a distance, the vehicle-usage indicator 430 can include a time-used indicator such as an hours indicator indicating, for example, how long a vehicle or an engine has been used.

[0048] Service provider identifier 402 can include information that indicates a name and geographic location of the se dee provider. Vehicle information 408 can include a vehicle identification number (VIN) 432 associated with the given vehicle and a description of the given vehicle. Service procedure information 418, 420, and 422 can include information within distinct RO sections 424, 426, and 42,8, respectively, of original RO 400. The service procedure information within any one distinct RO section 424, 426, and 428 can be unrelated to the sendee procedure information with any other distinct section. Alternatively, two or more distinct sections including service procedure information can pertain to related service operations performed on the given vehicle.

[0049] Original RO 400 includes labor operation codes (LOCs). The LOCs can conform to those defined by a vehicle manufacturer, a service provider that generates an RO, a service information provider, such as Mitchell Repair Information, LLC, Poway, California, or some other entity. For simplicity of FIG. 4, the LOCs are shown within parenthesis, such as (C45) and (CI 17, C245). Distinct LOC within parenthesis are separate by a comma. Each labor operation code (LOC) can refer to a particular operation performed to the given vehicle. Processor 204, executing CRPI 218, can use a LOC to determine what type of service or repair operation was performed to the given vehicle. Using the LOC in that manner is helpful if oilier information regarding that operation is incomplete or described using non-standard phrases or terms. Processor 204 can also use LOC to determine context for the service procedure information on or within the RO.

[0050] Multiple portions of text on an RO, such as original RO 400, can be grouped as phrases. When comparing contents of an RO to various terms of taxonomy term database 216, such as mapping terms, standard terms, or context terms, words within a given proximity to one or more other words on original RO 400 can be grouped as a phrase to be compared to the mapping, standard, or context terms. The given proximity can be within X words, where X equals 1, 2, 3, 4, 5, or some other number of words. As an example, service procedure information 418 states "Check starter/ignition system." The words "Check" and "ignition system" are within 3 words of one another. In accordance with an embodiment in which the given proximity is 4 word, the words "Check" and "ignition system" can be grouped as the phrase "Check ignition system" for comparison to mapping, standard, context terms, or labor operation codes.

[0051] The mapping, standard, context terms, or labor operation codes can be stored as part of taxonomy term database 216. Taxonomy term database 216 can include data that identifies words or phrases that are associated with one another. The association can be based on the words or phrases having a common meaning. The words or phrases identified as being associated with one another can be referred to a "taxonomy database group" or, more simply, a "taxonomy group."

[0052] Taxonomy term database 216 can include one or more taxonomy groups, and each taxonomy group can include one or more taxonomy terms (e.g., words or phrases). As an example, taxonomy term database 216 can include data that identifies the following phrases as a taxonomy group: (i) stalls when cold, (i) engine quits when temperature is low, (iii) engine dies in the morning, (iv) dies in the morning, (v) dies in the AM, and (vi) engine stalls on cold mornings.

[0053] Each taxonomy group can be associated with a standard term, which could be a first word or first phrase added to the taxonomy group. Alternatively, a word or phrase subsequently added to the taxonomy group can be the standard term for the taxonomy group. The words or phrases other than the standard term within a taxonomy group can be mapping terms. The words or phrases within each taxonomy group can be obtained from an RO. An administrator can approve adding or modifying any taxonomy group by, for example, processor 204 executing CRPI 218. Terms within taxonomy term database 216 can be compared to terms on a computer-readable RO. A mapping term on an original RO and found within a given taxonomy group can be represented on a presentable RO by a standard term for the given taxonomy group.

[0054] RO 214 can include original RO 400 as a computer-readable version of original RO 400. RO 214 can include one or more other computer-readable RO arranged like original RO 400 and one or more other computer-readable RO arranged in an RO configuration that differs from original RO 400. The other RO configurations typically include at least one of the types of information described above as being a part of original RO 400.

[0055] An RO stored within RO 214, such as original RO 400 or another RO, can include searchable text or symbols (e.g., text, symbols, or text and symbols). As an example, a symbol on an RO can include an empty check box or a checkbox and a checkmark inside the checkbox. Original RO 400 can be modified to include a presentable RO 500 (shown in FIG. 5) that represents original RO 400 or data thereon. Additionally or alternatively, presentable RO 500 can be distinct and separate from original RO 400.

[0056] Processor 204 can search the text, symbols or other content on an RO of RO 214 or the meta-data associated with an RO to associate an RO within a cluster of RO (or more simply, an RO cluster). Each cluster of RO can be associated with defined RO attributes, such as a diagnostic trouble code (DTC), action, or component listed on the RO. Other attributes of the information recorded on an RO can be associated with an RO cluster. Table 1 shows data identifying twenty-five clusters identified with ID 1 through 25, inclusive. The cluster size indicates how many RO have been associated with the respective cluster. The cluster size can be modified as or after additional RO are added to RO 214 or after an RO is transferred from one cluster to a different cluster. Table 1 shows examples of DTC, Action, and component attributes associated with each respective RO cluster.

[0057] Table 1 can be modified to include a separate column for other attributes as well. The other attributes can identify RO attributes such as, but not limited to, a customer complaint, a date, or a labor operation code (LOC). As an example, the customer complaint can include, but is not limited to, terms such as rattles, won't start, and vibrates. Auto- generated repair-hints for those example customer complaint terms can include repair hints identifying a way to stop a vehicle from rattling, a way to fix a vehicle that does not start, and a way to stop a vehicle from vibrating, respectively. [0058] Table 2 below shows an example of data included on 25 of the 2,088 RO associated with the RO cluster ID 18 shown in Table 1. The RO data in Table 2 includes an RO identifier that can, for example, be assigned by a VRT or VRD system 102. The RO data in

Table 2 also includes year/make/model/engine attributes associated with each RO.

[0059] Some vehicle models are associated with a sub-model attribute. Some vehicle models are not associated with a sub-model attribute. Table 2 can be modified to include a separate column to include sub-model attributes for vehicles that are associated with a submodel attribute. As an example, RO ID 7923 pertains to a Ford Pickup F 150 make and model. The term "F 150" can be referred to as a sub-model attribute. Other sub-model attributes for Ford Pickup models can include the "F250" and "F350" sub-model attributes. A sub-model attribute can be included on an RO. Searching for RO or repair-hints based on a sub-model in addition to Y/M/M/E attributes can lead to search results having RO or repair- hints associated with a particular sub-model, but not the oilier sub-model(s) of a particular vehicle having particular Y/M/M/E attributes. The "S" within Y/M/M/S/E can represent a sub-model attribute.

[0060] Table 2 can be modified to include a separate column for other attributes as well The other attributes can identify system (Sys) attributes such as, but not limited to, a transmission attribute, a suspension attribute, and an audio system attribute. A set of attributes including a system attribute can be referred to as Y/M/M/E/Sys attributes.

[0061] Vehicle leverage data 224 can include computer-readable data that identifies different vehicle models built on a common vehicle platfoim. Vehicles built on a common vehicle platform can have many similarities including the use of common parts or part numbers. Vehicles built on a common platform can experience similar vehicle symptoms that arise for similar reasons, such as failure of a part common to vehicles built on the common vehicle platform. Table 3 shows an example of data that can be stored as vehicle leverage data 224.

[0062] Processor 204 can generate an RO cluster that covers multiple vehicle models, such as the three vehicle models of VLD-3 shown in Table 3. If RO 214 includes 100 RO for the Chevrolet Lumma APV model between 1990-1996 and a given repair condition, 150 RO for the Pontiac ^" Fran Sport models between 1990-1996 and the given problem, and 40 RO for the Oldsmobile Silhouette model between 1990-1196 and the given problem, processor 204 can generate three separate RO clusters for the 290 RO or a single RO cluster for the 290 RO. A greater quantity of RO can indicate a greater likelihood of a successful repair of the given problem.

Table 3 [0063] Processor 204 can use the exception data within vehicle leverage data 224 to exclude O pertaining to certain vehicle models from an RO cluster associated with a group of vehicles built on a common platform. For the exception data in Table 3, since the GMC Yukon uses a different radiator than the Cadillac Escalade, the Chevrolet Tahoe, and the Chevrolet Suburban, an RO cluster pertaining to a radiator for a GMC Yukon may not be grouped with an RO cluster pertaining to a radiator on Cadillac Escalades, Chevrolet Tahoes, and Chevrolet Suburbans.

[0064] Parts leverage data 226 can include data that identifies different vehicle models that use a common part produced by one or more part(s) manufacturer. For purposes of this description, a common part is a part that can be used in either of two or more vehicle models without altering the part or any of the two or more vehicles to use the common part. Various references to a common part, such as a part number or part name, used by any or all of the part(s) manufacturer and the manufacturer(s) of the different vehicle models can be used. Vehicle models using a common part can experience similar vehicle symptoms that arise for similar reasons, such as failure of the common part. Table 4 shows an example of data that can be stored as parts leverage data 226.

Table 4

5] Processor 204 can generate an RO cluster that covers a common vehicle part and multiple vehicle models, such as the coolant temperature sensor and three vehicle models of

PLD-1 shown in Table 4. If RO 214 includes 30 RO for the 2012 Cadillac Escalade model and the coolant temperature sensor, 40 RO for the 2012 Chevrolet Tahoe model and the coolant temperature sensor, and 20 RO for the 2012 Chevrolet Suburban model and the coolant temperature sensor, processor 204 can generate three separate RO clusters for the 70 RO or a single RO cluster for the 70 RO. A greater quantity of RO can indicate a greater likelihood of occurrence of a successful repair of a given problem arising from the coolant temperature sensor. [0066] CRPI 218 can include program instructions executable by processor 204 to carry out functions described herein or performable by VRD system 200. CRPI 218 can include program instructions that are executable to parse data from an original RO stored within RO 214 and to identify the sendee procedure information, vehicle identification, and parts usage information from the original RO for use in generating a presentable RO or to increment a count of a cluster size if a presentable RO pertaining to the original RO has already been generated, or to decrement a cluster size if processor 204 transfers an RO from one cluster to a different cluster.

[0067] CRPI 218 can include program instructions executable by processor 204 to generate, for each auto-generated repair-hint and based on the RO stored in RO 214, metadata associated with at least one set of search terms. Meta-data 222 can include meta-data generated by processor 204 based the information listed on original RO 400 including, but not limited to the LOC and a definition of the LOC.

[0068] CRPI 218 can include program, instructions executable by processor 204 to determine that words or phrases within service procedure information, such as sen-ice procedure information 418, 420, or 422, are within one or more taxonomy groups of taxonomy term database 216, and to associate (e.g., relate) that sendee procedure information with the one or more taxonomy groups. The sendee procedure information associated with any given taxonomy group can be part of a new RO cluster or additional service procedure information to be added to an RO cluster or to modify an RO cluster.

[0069] CRPI 218 can include program, instructions executable by processor 204 to perform any one or more of the operations, functions, or actions illustrated in blocks 602-606 in Figure 6 and blocks 702-706 in Figure 7 and as described below in this description.

[0070] Text strings 228 can include strings of text, (e.g., two or more words, numbers or symbols). A text string can include one or more gaps for inserting meta-data to complete the text string. A text string can include a complete text string without any gaps. Processor 204 can select one or more text strings to associate with a set of terms (e.g., search terms) that can be entered or received to search for a repair hint of repair hints 220. Processor 204 can select the meta-data to insert into the gap(s) of a text string. Text strings 228 can include text strings entered by user interface 206. Text strings 228 can include text strings received by network interface 208.

[0071] Search terms 230 can include various sets of search terms. A set of search terms can include vehicle-ID search terms 232 or a symptom criterion 234. A first example set of search terms can include search terms received by network interface 208 as part of a request for a repair hint. The first example set of search terms can include search terms that are nonstandard terms in taxonomy terms database 216 and can be referred to as non-standard search terms (NSST), Processor 204 can identify, within taxonomy term, database 216, standard terms that match the search terms received by network interface 208 and then use any standard terms included within the received search terms or identified from taxonomy term database 216 to search for a repair hint. The non-standard search terms stored as part of search terms 230 can subsequently be reviewed by processor 204 or a human using RO manual entry device 202 or user interface 206 for inclusion as part of taxonomy term database 216.

[0072] A second example set of search terms can include standard sets of search terms and can be referred to as standard search terms (SST). A standard set of search terms can include standard vehicle-ID search terms, such as Y/M/M E attributes, defined in taxonomy term database 216 and standard symptom criterion defined in taxonomy term database 216. Processor 204 can associate one or more standard sets of search terms with a repair hint or a repair order. A set of search terms associated with a repair hint or repair order can be stored as meta-data associated with that repair hint or repair order. Taxonomy term database 216 can include search terms 230. The second example set of search terms 230 can be associated with one more sets of search terms like the first example set of search terms.

[0073] Table 5 shows an example of search terms that can be stored in search terms 230. NSST-227 is associated with SST-15. SST-15 is associated with RO ID 3915. Repair hint 510 on RO ID 3915 can be identified in response to receiving NSST-227, determining that SST-15 is associated with NSST-227, and determining RO ID 3915 is associated with SST- 15. SST-1456 is a set of standard search terms having symptom criterion common to SST-15 and SST-1456, and a Y/M/M/E attribute that differs from the Y/M/M/E for SST-15 only by the model years (i.e., 2000 instead of 1999). SST-15 and SST-1456 are both associated with RO ID 3915. This association can be determined based on vehicle leverage data 224 or parts leverage data 226.

Table 5

[0074] The vehicle-ID search terms 232 is one example of search terms that can be included within search terms 230. Vehicle-ID search terms 232 can include various selectable attributes. For example, the attributes of vehicle-ID search terms 232 can include Y/M/M/E attributes. As another example, the attributes of vehicle-ID search terms 232 can include Year Make Model/Sub-model/Engine (Y/M/M/S/E) attributes as discussed with respect to Table 2. As another example, the attributes of vehicle-ID search terms 232 can include Year/Make/Model/Engine/System (Y/M/M/E/Sys) attributes. As another example, the attributes of vehicle-ID search terms 232 can include Year/Make/Model/Sub- model Engine/System (Y/M/M/S/E/Sys) attributes .

ΘΘ75] The system (Sys) attribute vehicle-ID search terms 232 can indicate or represent a system (e.g., one or more systems) or a component (e.g., one or more components) within a vehicle. As an example, the system or component within the vehicle can identify (i) a powertram transmission within the vehicle (e.g., a 4-speed automatic transmission with overdrive), (ii) a rear differential within the vehicle (e.g., a rear differential with a 4.11 : 1 gear ratio), (iii) an electric alternator within the vehicle (e.g., a 100 ampere alternator), (ivj a heater, ventilation, and air-conditioning (HVAC) system installed within the vehicle (e.g., a dual-zone (e.g., a driver side and passenger side) HVAC system), or some other system or component installed within, attached to, or other otherwise operating on or in the vehicle.

[0076] The order of any of the vehicle-ID search terms 232 described herein can be rearranged as desired. For example, the order of the Y/M/M/E attributes could be rearranged as Make Model Engine/Y ear (M/M/E/Y) attributes or in another arrangement.

[0077] FIG. 5 shows an example content of a presentable RO 500 including an RO identifier 502, RO timing information 504, RO vehicle identifier 506, a vehicle service request 508, an auto-generated repair-hint 510, meta-data 512, and a usage indicator 514. Presentable RO 500 is based on service procedure information 418 an original RO 400. RO identifier 502 is "3915," which is also shown in the seventeenth row of Table 2. RO timing information 504 includes a year designator (i.e., 2009) to indicate a time that pertains to RO ID 3915. That time can indicate, for example, when original RO 400 was written, completed, or submitted to VRD system 102. RO timing information could include other or different time information such as a day, month, or hour-of-a-day. RO vehicle identifier 506 includes the year/make/model/engine attributes shown in the seventeenth row of Table 2 for RO ID 3915. Additional or other attributes of the given vehicle identified on original RO 400 can be included on presentable RO 500.

[0078] Presentable RO 500 includes elements in or based on original RO 400. Presentable RO 500 can be stored within data storage device 210 with or as part of original RO 400. Additionally or alternatively, presentable RO 500 can be stored separately and distinctly from original RO 400,

[0079] Vehicle service request 508 includes information pertaining to a vehicle service request on an RO within RO 214. Vehicle service request 508 can include one or more text strings from text strings 228. As an example, each sentence within vehicle service request 508 can be a separate text string. For example, a text string can include the text "Customer states the vehicle has [insert customer complaint]." The text within the square brackets (i.e., [ ]) identifies meta-data or a taxonomy term to be inserted to complete the text string. The portion of a text string within the square brackets can be referred to as a "text string gap" or more simply, "a gap." Processor 204 can select the meta-data or the taxonomy term based on information included on an original RO pertaining to RO ID 3915 received at VRD system 102. The text string "Please diagnose and advise" is an example of a text string without any gaps in which text is to be inserted to complete the text string. The term "MAF sensor" in the text string "Customer states please replace the MAF sensor" can be selected by processor to insert into the text string from meta-data 512.

[0080] Auto-generated repair-hint 510 can include one or more text strings from text strings 228. As an example, each sentence within auto-generated repair-hint 510 can be a separate text string. For example, a text string can include the text "Technician scan tested and verified the DTC [insert first Pcode] and DTC [insert second PcodeJ." Processor 204 can select the DTC (e.g., Pcode) identifiers "P0171" and "P0174" from meta-data 512 to complete the text string by inserting those DTC (e.g., Pcode) identifiers into the text string gaps. Processor 204 can select the meta-data based on information, such as a LOC, included on an original RO pertaining to RO ID 3915 received at VRD system. 102.

[0081] As another example, a text string can include multiple sentences within auto- generated repair-hint 510, such as all of the sentences, but the first sentence, within auto- generated repair-hint 510. Processor 204 can select fuel pump pressure readings (e.g., 30 and 40) to insert within the second sentence of that text string, and to select a component name (e.g., MAF sensor) from meta-data 512 or taxonomy term database 216 to insert in the 4 ^th through 9 ¹ sentences of the multiple -sentence text string. Those inserted terms are underlined within FIG. 5.

[0082] Meta-data 512 can be stored with presentable RO 500 within RO 214. Additionally or alternatively, meta-data 512 can be stored within meta-data 222 along with a tag or reference to presentable RO 500.

[0083] Usage indicator 514 indicates a distance in miles associated with RO 500. Usage indicator 514 can be used by processor 204 to determine whether to select auto-generated repair-hint 510 when searching for a repair-hint based on a set of search terms.

[0084] Next, FIG. 3 is a block diagram showing details of example a vehicle repair tool (VRT) 300. VRT 300 can include or be arranged as a machine. VRT 300 includes a user interface 302, a processor 304, a network interface 306, and a data storage device 308, all of which can be linked together via a system bus, network, or other connection mechanism 310. One or more of the VRT shown in FIG. 1 can be arranged like VRT 300. VRT 300 can be used within system 100 like any of the VRT shown in FIG. 1.

[0085] Processor 304 can be configured to execute computer-readable program instructions, such as comp ter-readable program instractions (CRPI) 312 stored within data storage device 308. For purposes of this description, processor 304 executing CRPI 312 to perform some function described herein can include executing a portion of CRPI 312 or the entirety of CRPI 312. Executing a portion or the entirety of CRPI 312 can include executing some of the computer-readable program instractions multiple times.

[0086] Data storage device 308 can include a non-transitosy computer-readable storage medium (i.e., two or more computer-readable storage mediums) readable by processor 304. The or each non-transitory computer-readable storage medium can include volatile or nonvolatile storage components, such as optical, magnetic, organic or other memory or disc storage, which can be integrated in whole or in part with a processor 304.

[0087] User interface 302 can include an interface to components that are configured to enter data or information into VRT 300 or to components that are configured to present data or information output by VRT 300. Any of those components can be referred to as a VRT user interface component. User interface 302 can include one or more audio/visual ports or communication ports that connect to a VRT user interface component by a wired or wireless user interface communication link. Data or information entered into VRT 300 by user interface 302 can include data or information for preparing an RO, such as original RO 400.

[0088] User interface 302 can include one or more of the VRT user interface components. As an example, the VRT user interface components can include an infrared remote control device, a display device, a loud speaker configured to convert electrical signals to audible sounds, a keyboard, a touch screen, a pointing device, such as a computer mouse, or some other component for generating signals to enter data or information into VRT 300 or to present data or information output by user interface 302. User interface 302 can include a transmitter or transceiver to provide the data or information to another VRT user interface component.

[0089] Network interface 306 can include an interface to one or more communication networks, such as network 104. For use with wireless communication networks, network interface 306 can include one or more antennas for transmitting or receiving wireless communications. Network interface 306 can include one or more communication posts configured to connect to a wired communication link of a network. Examples of the wired communication link are listed elsewhere herein. Network interface 306 can include a network controller including a transmitter, a receiver, or a transceiver. The transmitter or transceiver can provide data or information to a communication port for transmission as network communications over the connected network. The receiver or transceiver can receive data or information received at a communication port from the connected network. The data or information provided by network interface 306 to the network can include an RO.

[0090] CRPI 312 can include program instructions for generating an RO, such as original RO 400, based on data input by user interface 302 or a user interface component thereof. CRPI 312 can include program instructions for performing diagnostic functions for diagnosing a vehicle identified on an RO. As an example, performing the diagnostic functions can include checking a diagnostic trouble code (DTC), such as a DTC 1 17, as identified in section 428 of original RO 400. CRPI 312 can include program instructions for (i) displaying, by user interface 302, vehicle-ID attributes selectable to form a set of search terms, symptom criterion selectable to form part of the set of search terms, and a field for entering a usage indicator, (ii) receiving a selection of the set of search terms, (iii) providing the selected set of search terms to network interface 306 for transmission of the selected search terms to VRD system 102, (iv) receiving, by network interface 306, a repair hint, such as an auto-generated repair-hint, from VRD system 102, and (v) displaying the received repair hint using user interface 302,

[0091] A VRT, such as VRT 300 or any of the VRT shown in FIG. I, can include, or be configured as, a smartphone, a tablet device, a laptop computer, a desktop computer, or an embedded computing device, such as the VERDICT ^1M Diagnostic and Information System and the VERSUS® PRO Integrated Diagnostic and Information System, both of which are available from Snap-on Incorporated, Kenosha, Wisconsin. Accordingly, a VRT can also include computer-readable program instructions to perform features such as, but not limited to, guided component tests, an online expert forum, electrical measurements, waveform capture, displaying vehicle records, etc.

Ill . FIRST EXAMPLE OPERATION

[0092] Figure 6 is a flowchart illustrating a method 600, according to an example implementation. Method 600 shown in Figure 6 (and other processes and methods disclosed herein) presents a method that can be implemented within an arrangement involving, for example, system 100, VRD system 200, and/or VRT 300 (or more particularly by one or more components or subsystems thereof, such as by a processor and a non-transitory computer-readable medium having instructions that are executable to cause the device to perform functions described herein). Additionally or alternatively, method 600 may be implemented within any other arrangements and systems.

[0093] Method 600 and other processes and methods disclosed herein may include one or more operations, functions, or actions as illustrated by one or more of blocks 602-606. Although the blocks are illustrated in sequential order, these blocks may also be performed in parallel, and/or in a different order than those described herein. Also, the various blocks may be combined into fewer blocks, divided into additional blocks, and/or removed based upon the desired implementation.

[0094] In addition, for the method 600 and other processes and methods disclosed herein, the flowchart shows functionality and operation of one possible implementation of present implementations. In this regard, each block may represent a module, a segment, or a portion of program code, which includes one or more instmctions executable by a processor for implementing specific logical functions or steps in the process. The program, code may be stored on any type of computer-readable medium, for example, such as a storage device including a disk or hard drive. The computer readable medium may include non-transitory computer-readable medium, for example, such as computer-readable media that stores data for short periods of time like register memory, processor cache and Random Access Memory (RAM). The computer-readable medium may also include non-transitory media, such as secondary or persistent long term storage, like read only memory (ROM), optical or magnetic disks, compact-disc read only memory (CD-ROM), for example. The computer-readable media may also be any other volatile or non-volatile storage systems. The computer-readable medium may be considered a computer readable storage medium, for example, or a tangible storage device. In addition, for the method 600 and other processes and methods disclosed herein, each block in Figure 6 may represent circuitry that is wired to perform the specific logical functions in the process.

[0095] At block 602, method 600 involves detennining, by at least one processor, that a particular computer-readable vehicle repair order (RO) corresponds to an existing cluster of computer-readable vehicle repair orders (ROs) due to the particular RO including data that refers to a particular vehicle symptom, where the existing cluster is arranged to contain ROs that correspond to the particular vehicle symptom.

[0096] In an example implementation, a processor (e.g., processor 204) may be configured to evaluate a particular RO. This particular RO may be one of the ROs 214 stored in data storage device 210, may be a new RO received from RO manual entry device 202, or may be a new RO received from network interface 208 by way of network 104, among other possibilities. Moreover, this particular RO can be an original RO, such as an RO generated by a VRT shown in FIG. 1 or entered using RO manual entry device 202, or the particular RO may be a presentable RO generated by VRD system. 200.

[0097] \\¾ile evaluating the particular RO, the processor 204 may determine that the particular RO corresponds to an existing cluster of ROs. This existing cluster may be a cluster within which the processor 204 has previously associated one or more ROs. Hence, the existing cluster may have cluster size of at least 1 (one), thereby indicating that at least one RO has been associated with this existing cluster. The at least one RO thai has been associated with this existing cluster may be the particular RO at issue. That is, the particular RO may have already been associated with the existing cluster and thus the existing cluster already contains the particular RO. Alternatively, the particular RO may be a new RO that has not yet been added to (e.g., associated with) the existing cluster. In this case, the processor 204 may determine that the particular RO corresponds to the existing cluster and should thus be added to the existing cluster so as to increase the cluster size.

[0098] More specifically, the existing cluster can be associated with particular defined RO attributes, such as with a particular vehicle symptom for instance. This particular vehicle symptom may be a particular DTC, such as DTC P0171 shown in Figure 4 for example. Alternatively, this particular vehicle symptom may be one of the symptom criterion 234, such as "Emissions and MAF failed" shown in Table 5 above for example. The particular vehicle symptom could also take on other forms. In either case, the existing cluster may be arranged to contain ROs that correspond to the particular defined RO attributes, such as to the particular vehicle symptom for instance. [0099] In an example arrangement, the processor 204 may determine that the particular RO corresponds to the existing cluster in one of various ways. For example, if the existing cluster already contains the particular RO, the processor 204 may determine that the particular RO corresponds to the existing cluster simply by determining that the existing cluster already contains the particular RO. For instance, this may involve the processor 204 determining the cluster ID associated with the particular RO.

[00100] In another example, whether the existing cluster already contains the particular RO or whether the particular RO is a new RO, the processor 204 may determine that the particular RO corresponds to the existing cluster by determining that the particular RO includes RO attributes that match the above-mentioned particular defined RO attributes. To do so, processor 204 can search the text, symbols or other content on the particular RO or the meta-data associated with the particular RO in order to associate the particular RO within the existing cluster. For instance, the processor 204 may determine that the particular RO includes content related to the particular vehicle symptom and may thus associate the particular RO with the existing cluster due to the existing cluster being arranged to contain ROs that correspond to the particular vehicle symptom. Other examples are also possible.

[00101] In some cases, the existing cluster being arranged to contain ROs that correspond to the particular vehicle symptoms may specifically involve arranging the existing cluster to contain ROs that correspond to the particular vehicle symptom without also corresponding to the replacement of a particular vehicle component to resolve this particular vehicle symptom. ROs contained within such a cluster may thus contain content related to the particular vehicle symptom but may not contain content that is related to a vehicle repair involving replacement of a particular vehicle component. In such cases, the processor 204 may determine that the particular RO corresponds to the existing cluster by determining that the particular RO contains content related to the particular vehicle symptom but does not contain content that is related to a vehicle repair involving replacement of a particular vehicle component.

[00102] Table 6 shows data identifying three clusters identified with ID 26 through 28, inclusive. The cluster size indicates how many RO have been associated with the respective cluster. Tire cluster size can be modified as or after additional RO are added to RO 214 or after an RO is transferred from one cluster to a different cluster. Table 6 shows examples of DTC, Action, and component attributes associated with each respective RO cluster. Of course, as noted above in relation to table 1, Table 6 can be modified to include a separate column for other attributes as well. The other attributes can identify RO attributes such as, but not limited to, a customer complaint, a date, or a labor operation code (LOC).

Table 6

[00103] As shown, these example clusters are each arranged to contain ROs that correspond to at least one particular vehicle symptom without also corresponding to the replacement of a particular vehicle component to resolve the at least one particular vehicle symptom. For instance, the cluster having a cluster ID of 2,6 is associated with a single vehicle symptom taking the form of DTC P0101. Whereas, the cluster having a cluster ID of 27 is associated with two vehicle symptoms that respectively take the form of DTC P0503 and DTC P0504. Of course, an example cluster could be associated with two or more vehicle symptoms. In either case, the above-mentioned existing cluster could be one of the example clusters shown in Table 6, among other possible clusters.

[00104] With this example arrangement, the above-mentioned particular RO may be one of the ROs in one of the clusters shown in Table 6. For instance, the particular RO may be one of the ROs associated with RO cluster ID 26. To illustrate. Table 7 next shows an example of data included on 5 of the 1,254 ROs associated with the RO cluster ID 26 shown in Table 6. The RO data in Table 7 includes an RO identifier that can, for example, be assigned by a VRT or VRD system. 102. The RO data in Table 7 also includes year/make/model/engine attributes associated with each RO. Of course, as noted above in relation to Table 2, Table 7 can be modified to include a separate column to include other attributes, such as sub-model attributes for vehicles that are associated with a sub-model attribute.

Table 7 [00105] At block 604, method 600 involves, in response to determining that the particular RO corresponds to the existing cluster, the at least one processor determining that the particular RO includes data, indicating an alternative repair that defines a vehicle repair for resolving the particular vehicle symptom other than by replacement of a particular vehicle component.

[00106] In an example implementation, as discussed above, the processor 204 may evaluate the particular RO and may determine that the RO corresponds to the existing cluster. Upon this determination, tlie processor 204 may determine whether or not the particular RO includes data that is related to at least one alternative repair. This alternative repair may be any repair that can be used to resolve the particular vehicle symptom, other than by replacement of a particular vehicle component. For example, section 424 of original RO 400 includes service procedure information 418 stating an alternative repair of "recalibrated MAF". Additional examples are discussed below.

[00107] The processor 204 may determine whether or not the particular RO includes data that is related to an alternative repair for various reasons. For example, as noted above, the existing cluster may contain ROs that correspond to tlie particular vehicle symptom without also corresponding to the replacement of a particular vehicle component to resolve this particular vehicle symptom. In this example, an individual (e.g., a repair technician) using a vehicle repair tool may encounter a vehicle exhibiting tlie particular vehicle symptom at issue. However, the individual may evaluate ROs within the existing cluster (or repair hints based on the existing cluster) but may not be able to determine the appropriate repair for the vehicle. More specifically, the individual may not be able to determine the appropriate repair for the vehicle because tl e existing cluster is not associated with any particular repair and thus the individual may not be able to determine which particular repair is most suitable for vehicles exhibiting this particular vehicle symptom. Moreover, determining such an alternative repair may assist in generating and providing auto-generated repair-hints that include the alternative repair when appropriate. Additional reasons are discussed below in association with Figure 7.

[00108] Alternative repairs can take on various forms. In one example, an alternative repair may involve cleaning of a particular vehicle component. In another example, an alternative repair may involve recalibration of a particular vehicle component. In yet another example, an alternative repair may involve removal of a particular vehicle component. In yet another example, an alternative repair may involve addition of a particular vehicle component. In yet another example, an alternative repair may involve an adjustment to a particular vehicle component. In yet another example, an alternative repair may involve fixing of a particular vehicle component. In yet another example, an alternative repair may involve reprogramming of a particular vehicle component. In yet another example, an alternative repair may involve aligning of a particular vehicle component. In yet another example, an alternative repair may involve rebalancing of a particular vehicle component. In yet another example, an alternative repair may involve welding of a particular vehicle component. In yet another example, an alternative repair may involve re-securing of a particular vehicle component. In yet another example, an alternative repair may involve rewiring of a particular vehicle component. In yet another example, an alternative repair may involve shimming of a particular vehicle component. Various other examples are also possible without departing from the scope of the disclosure.

[00109] The processor 204 may determine whether or not the particular RO includes data that is related to an alternative repair in various ways. For example, processor 204 can search the text, symbols or other content on the particular RO or the meta-data associated with the particular RO. While doing so, the processor 204 may compare contents of the particular RO to various terms of taxonomy term database 216, such as mapping terms, standard terms, or context terms. In particular, as noted above, taxonomy term database 216 can include one or more taxonomy groups, and each taxonomy group can include one or more taxonomy terms (e.g., words or phrases or LOCs). With this arrangement, CRPI 218 can include program instructions executable by processor 204 to determine that words or phrases (or LOCs) within the particular RO (e.g., within service procedure information) are within one or more taxonomy groups of taxonomy term database 216, and to associate (e.g., relate) that particular RO with the one or more taxonomy groups.

[00110] As such, at least one taxonomy group of taxonomy term, database 216 may include various terms representative of (e.g., associated with) various alternative repairs. In one case, these terms may represent alternative repairs without specifying a particular component that could be associated with the alternative repair. For example, taxonomy term database 216 can include data that identifies the following words/phrases (among other words/phrases) as an example taxonomy group: (i) cleaning, (ii) recalibration, (iii) removal, (iv) addition, (v) adjustment, (vi) fixing, and (vii) reprogramming. These may be listed as a combination of characters (e.g., ^" 'cleaning") or may specifically take the form of the labor operation codes (LOCs) discussed above, among other possibilities. With this arrangement, the processor 204 may determine that word(s) or phrase(s) (or LOCs) within the particular RO are within this example taxonomy group and may associate (e.g., relate) that particular RO with the example taxonomy group. For instance, the processor 204 may determine that the particular RO includes the word "adjustment" and may thus associate the particular RO with tins example taxonomy group.

[00111 ] In this case, the processor may then determine a particular component associated with the identified term (e.g., "adjustment" or particular LOC) representative of the alternative repair. To do so, the processor 204 may determine words or phrases in the particular RO that are within a given proximity to the identified term in the particular RO. The processor 204 may then determine whe ther any of these determined word(s) or phrase(s) are representative of a particular component. The processor 204 may do so in one of various ways.

[00112] For instance, at least one taxonomy group of taxonomy tenn database 216 may- include various terms representative of (e.g., associated with) various particular components. For example, taxonomy term database 216 can include data that identifies the following words/phrases (among other words/phrases) as an example taxonomy group: (i) Mass Airflow Sensor, (ii) Engine, (iii) Chassis, and (iv) Air Filter. In another instance, at least one taxonomy group of taxonomy term database 216 may include various terms each representative of a variation by which an individual could refer to a particular component (e.g., Mass Airflow Sensor). For example, taxonomy term database 216 can include data that identifies the following words/phrases (among other words/phrases) as an example taxonomy- group: (i) MAS, (ii) Mass Airflow Sensor, and (iii) MA Sensor.

[00113] In yet another instance, at least one taxonomy group of taxonomy term database 216 may include an alternative repair modifier term associated with an alternative repair tenn and a particular vehicle component. In one situation, this alternative repair modifier term can represent an aspect of the particular vehicle component for which alternative repair is carried out. For example, an alternative repair may involve adjustment of engine timing or adjustment of engine idle. In this example, "adjustment" is the alternative repair term, "engine" is the particular vehicle component, and "timing" and "idle" are alternative repair modifier terms. In another situation, this alternative repair modifier term, can represent a part (e.g., a wire, a harness, or a connector) that is extending from or otherwise connected to the particular vehicle component. For example, an alternative repair may involve realignment of an engine connector. In this example, "realignment" is the alternative repair term, "engine" is the particular vehicle component, and "connector" is the alternative repair modifier tenn. Thus, for example, taxonomy tenn database 216 can include data that identifies the following words/phrases (among other words/phrases) as an example taxonomy group: (i) timing, (ii), idle, (iii) wire, (iv) harness, and (v) connector.

[00114] Regardless, the processor 204 may determine that at least one of the above- mentioned determined word(s) or phrase(s) are representative of a particular component by determining that such word(s) or phrase(s) within the particular RO are within at least one such example taxonomy group. Upon such a determination, the processor 204 may associate (e.g., relate) that particular RO with such an example taxonomy group. For instance, the processor 204 may determine that the particular RO includes the term "Mass Airflow Sensor" and that tins word is within a given proximity to the identified alternative repair term of "adjustment". In this instance, the processor may then determine that the term "Mass Airflow Sensor" is within the above-mentioned example taxonomy group and may thus associate the particular RO with this example taxonomy group. Thus, with this arrangement, the processor 204 can use a combination of such associations to determine that the particular RO includes data representative of an alternative repair of "adjustment to a Mass Airflow Sensor". The processor 204 may do so, for instance, by referring to mapping data that maps various associations (or combinations of associations) to alternative repair indicators indicating that particular associations (or combinations of associations) correspond to an alternative repair.

[00115] In this manner, the processor 204 can associate the particular RO with at least one taxonomy group containing at least one term representative of alternative repairs (e.g., adjustment) and thus determine that the identified term is an alternative repair term. Also, the processor 204 can associate the particular RO with at least one taxonomy group containing terms representative of at least one particular component (e.g.. Mass Airflow Sensor) and may thus determine that tins term (e.g., a word within a given proximity to the word "adjustment") is the particular component associated with the alternative repair term. In some cases, the processor 204 may also associate the particular RO with at least one taxonomy group containing terms representative of at least one alternative repair modifier term (e.g., connector) and may thus determine that this term is a modifier term associated with the alternative repair term and/or with the particular vehicle component. Note that the processor 204 can identify the alternative repair term, the particular component associated with the alternative repair term, and/or the modifier term in any order.

[00116] In another case, at least one taxonomy group of taxonomy term database 216 may include various terms representative of (e.g., associated with) various alternative repairs such that these terms may represent alternative repairs while also specifying a particular component associated with the alternative repair. In one example, taxonomy term database 216 can include data that identifies the following words/phrases (among other words/phrases) as an example taxonomy group such that the phrases are in relation to an alternative repair of a particular component (e.g., Mass Airflow Sensor): (i) cleaning of Mass Airflow Sensor, (ii) recalibration of Mass Airflow Sensor, (iii) removal of Mass Airflow Sensor, (iv) addition of Mass Airflow Sensor, (v) adjustment to Mass Airflow Sensor, (vi) fixing of Mass Airflow Sensor, and (vii) reprogramming of Mass Airflow Sensor. These may be listed as a combination of characters (e.g., "cleaning of Mass Airflow Sensor") or may specifically take the form of listing of an LOC along with a component, among other possibilities.

[00117] In another example, taxonomy term database 216 can include data that identifies the following words/phrases (among other words/phrases) as an example taxonomy group such that the phrases are related to variations by which an individual could refer to alternative repairs of a particular component (e.g., Mass Airflow Sensor): (i) cleaning of Mass Airflow Sensor, (ii) cleaning of MAS, (iii) clean MAF sensor, (iv) recalibrate MAF sensor, (v) recalibration of Mass Airflow Sensor, and (vi) recalibration of a Mass Airflow Sensor. As noted, these may be listed as a combination of characters (e.g., "recalibrate MAF sensor") or may specifically take the form of listing of an LOC along with a component, among other possibilities.

[00118] In yet another example, taxonomy term database 216 can include data that identifies the following words/phrases (among other words/phrases) as an example taxonomy group such that the phrases are in relation to various alternative repairs of various components: (i) cleaning of Mass Airflow Sensor, (ii) recalibration of Mass Airflow Sensor, (iii) removal of Engine, (iv) addition of Engine, (v) adjustment to Air Filter, (vi) fixing of Air Filter, and (vii) reprogramming of Mass Airflow Sensor. As noted, these may be listed as a combination of characters (e.g., "adjustment to Air Filter") or may specifically take the form, of listing of an LOC along with a component, among other possibilities. Various other examples are also possible.

[00119] Regardless, within such examples, the processor 204 may determine that word(s) or phrase(s) (or LOCs) within the particular RO are within at least one such example taxonomy group and may associate (e.g., relate) that particular RO with the example taxonomy group. For instance, the processor 204 may determine that the particular RO includes the phrase "removal of Engine" and may thus associate the particular RO with the appropriate example taxonomy group containing the term "removal of Engine". In this manner, the processor 204 can associate the particular RO with at least one taxonomy group containing terms that represent alternative repairs while also specifying a particular component associated with the alternative repair. Tims, with this arrangement, the processor 204 can use such an association to determine that the particular RO includes data representative of an alternative repair (e.g., "removal of engine").

[00120] In a further aspect, multiple portions of text of the particular RO can be grouped as phrases. When comparing contents of the particular RO to various terms of taxonomy term database 216, words within a given proximity to one or more other words on the particular RO can be grouped as a phrase to be compared to the mapping, standard, or context terms in the taxonomy term database 216. As noted above, the given proximity can be within X words, where X equals I, 2, 3, 4, 5, or some other number of words.

[00121] Within this arrangement, the processor 2,04 may determine various phrases in the particular RO and may then determine whether such phrases correspond to alternative repairs. To do so, the processor 204 may compare each such phrase to terms in the taxonomy term database 216, such as to terms contained in a taxonomy group associated with alternative repairs (e.g., one of the example taxonomy groups discussed above). If the processor 204 determines that a phrase in the particular RO is within a taxonomy group containing terms related to alternative repairs, the processor 204 may associate the particular RO with this taxonomy group and may thus determine that the phrase corresponds to an alternative repair.

[00122] As an example, service procedure infonnation of the particular RO may state "fix component known as MAF sensor." The words "fix" and "MAF sensor" are within 3 words of one another. In accordance with an embodiment in which the given proximity is 4 words, the words "fix" and "MAF sensor" can be grouped as the phrase "fix MAF sensor" for comparison to mapping, standard, context terms, or labor operation codes. Other cases and examples are also possible.

[00123] In yet a further aspect, the processor 204 could also determine that the particular RO includes more than one alternative repair for resolving the particular vehicle symptom . For instance, the processor 204 may determine that the particular RO includes data indicating at least a first alternative repair and a second alternative repair. The first and second alternative repairs may both relate to vehicle repairs of the same particular vehicle component. Alternatively, the first and second alternative repairs may each relate to vehicle repairs of different vehicle components. In either case, any of the above aspect discussed in the context of a single alternative repair may also apply in the context of a particular RO including more than one alternative repair for resolving the particular vehicle symptom.

[00124] In yet a further aspect, as noted above, the processor 204 may determine that the particular RO does not contain content that is related to a vehicle repair involving replacement of a particular vehicle component. The processor 204 could make this determination in one of various ways. For example, the processor 204 may compare contents of the particular RO (e.g., of the service procedure information) to taxonomy groups as discussed above. If the processor 204 determines that the particular RO does not contain any contents that match terms within a taxonomy group related to replacement of a particular vehicle component, the processor 204 may thus determine that the particular RO does not contain content that is related to a vehicle repair involving replacement of a particular vehicle component. Additionally or alternatively, the processor 204 may refer to a parts information section of the particular RO to determine whether this section lists the particular vehicle component. If this section does not list the particular vehicle component, the processor 204 may determine or may otherwise increase determination confidence that the particular RO does not contain content related to replacement of the particular vehicle component.

[00125] Further, in some situations, the processor 204 may refer to the parts information section and may encounter a listed part number without there being a part name. In such situations, the processor 204 may refer to a parts database (e.g., within parts leverage data 226) that includes mapping data that maps various part numbers to various part names so as to determine a particular part name associated with the listed part number. If the processor 204 determines a particular part name in this manner, the processor 204 may determine that the particular RO contains content that is related to a vehicle repair involving replacement of a particular vehicle component. In this case, the processor 204 could perform actions as further discussed below in the context of Figure 7. Whereas, if the processor 204 cannot determine a particular part name in this manner, the processor 204 may provide a report for human review (as further discussed below) and/or may use tins as a determination (or as an increase in determination confidence) that the particular RO does not contain content that is related to a vehicle repair involving replacement of a particular vehicle component. Other examples are also possible.

[00126] At block 606, method 600 involves, in response to determining that the particular RO includes the data indicating the alternative repair, the at least one processor adding the particular RO to a different cluster of ROs, where the different cluster is arranged to contain ROs that correspond to the particular vehicle symptom and to the alternative repair.

[00127] In an example implementation, the processor 204 may determine that the particular RO includes at least one alternative repair and may then add this particular RO to a different cluster of ROs. This different cluster may be arranged to contain ROs that have data corresponding to the above-mentioned particular vehicle symptom as well as data corresponding to the determined alternative repair. For instance, a different cluster may contain ROs that correspond to a DTC P0101 and to the alternative repair of ^" 'Clean Mass Airflow Sensor". Of course, the different cluster could also involve other vehicle attributes and may thus be arranged to contain ROs that correspond to the particular vehicle symptom, to tlie alternative repair, and to these other vehicle attributes.

[00128] In one example situation, as noted above, the processor 204 may determine that the particular RO is a new RO that is received by the processor 204 before the particular RO has been added to any of the existing cluster and the different cluster. In this situation, the processor 204 may add the particular RO to both the existing cluster and to the different cluster. In another case, the processor 204 may add the particular RO to the different cluster without also adding the particular RO to the existing cluster. In yet another case, the processor 204 may add the particular RO to the existing and different clusters and perhaps could add the particular RO to another appropriate cluster. In yet another case, the processor 204 may add the particular RO to the different cluster without also adding the particular RO to the existing cluster, and perhaps could add the particular RO to another appropriate cluster. Other cases are also possible.

[00129] Note that an appropriate cluster may be a cluster other than the existing and different clusters. For instance, this appropriate cluster could be associated with a repair described in a section of the particular RO that is different than section(s) of the particular RO describing repair(s) associated with the existing cluster (e.g., as discussed below in the context of Figure 7) and/or different cluster. Hence, since such a repair can be described in a different section, the processor 204 could also add the particular RO to an appropriate cluster associated with this repair. By way of example, service information 418 of RO section 424 includes content related to an alternative repair (e.g., recalibrated MAF) while service information 422 of RO section 428 includes content related to a vehicle repair involving replacement of a vehicle component (e.g., remove/replace (R/R) coolant sensor). In this example, the processor 204 could thus add the particular RO to a different cluster associated with the alternative repair as well as to an appropriate cluster associated with the vehicle repair involving replacement of a vehicle component. In this manner, a repair technician could access the particular RO via the different cluster when repairing a vehicle that needs the alternative repair and could also access the particular RO via the appropriate cluster when repairing a vehicle (e.g., could be the same vehicle) that needs the vehicle repair involving the replacement of the vehicle component. Other examples are also possible. [00130] In another example situation, as noted above, the processor 204 may determine that the particular RO is already contained in the existing cluster. In tins situation, the processor 204 may add the particular RO to the different cluster and may also keep the particular RO in the existing cluster such that the particular RO is then contained in both the existing cluster and the different cluster. In another case, the processor 204 may add the particular RO to the different cluster and may also remove the particular RO from the existing cluster such that the particular RO is then contained in the different cluster and is no longer contained in the existing cluster. In yet another case, the processor 204 may add the particular RO to the different cluster, may also keep the particular RO in the existing cluster, and may also add the particular RO to another appropriate cluster (e.g., a cluster other than the existing and different clusters). In this case, the particular RO may then be contained in the existing cluster, the different cluster, and the other appropriate cluster. In yet another case, the processor 204 may add the particular RO to the different cluster, may also remove the particular RO from, the existing cluster, and may also add the particular RO to another appropriate cluster (e.g., a cluster other than the existing and different clusters). In this case, the particular RO may then be contained in the different cluster and the other appropriate cluster. Other cases are also possible.

[00131 ] Figs. 8 A to 8B illustrate example of movement of an RO between clusters. In particular. Fig. 8A shows an example cluster 800 containing ROs 804 to 816 as well as example cluster 802 containing ROs 818 to 822. As illustrated, RO 814 is being moved from cluster 800 to cluster 802. Then, after the RO 804 has been moved, Fig. 8A shows the cluster 802 as containing RO 814 and the cluster 800 as no longer containing RO 814. Further, Figs. 9A to 9B illustrate example of addition of an RO to a cluster. In particular, Fig. 9A shows an example cluster 900 containing ROs 902 to 912. As illustrated, new RO 914 is being added to the cluster 900. Then, after the new RO has been added to the cluster 900, Fig. 9B shows the cluster 900 as containing RO 914. Other illustrations are also possible.

[00132] In an example arrangement, the processor 204 may use various techniques to add the particular RO to a cluster, to remove the particular RO from a cluster, to move the particular RO between clusters, and/or to keep the particular RO in a cluster. In one case, to add the particular RO to a cluster, the processor 204 may generate meta-data to associate the particular RO with an appropriate cluster ID and may then store this generated meta-data (e.g., within meta-data 222 along with a tag or reference to the particular RO). In another case, to remove the particular RO from a cluster, the processor 204 may (i) revise meta-data that associates the particular RO with the cluster ID so as to indicate that the particular RO is no longer associated with this cluster ID and may then (ii) store this revised meta-data. Alternatively, to remove the particular RO from a cluster, the processor 204 may remove meta-data that associates the particular RO with the cluster ID such as by removing this metadata from data storage 210.

[00133] In yet another case, to move the particular RO between clusters, the processor 204 may revise meta-data that associates the particular RO with a first cluster ID so as to indicate within the meta-data that the particular RO is no longer associated with this first cluster ID and is rather associated with a second cluster ID. Alternatively, to move the particular RO between clusters, the processor 204 may generate meta-data to associate the particular RO with a first cluster ID (and may then store this generated meta-data) while also removing or revising meta-data that associates the particular RO with a second cluster ID in the manner discussed above. In yet another case, to keep the particular RO in a cluster, the processor 204 may simply maintain any meta-data that associates the particular RO with tins cluster. Other cases are also possible.

[00134] In an example implementation, the processor 204 could refer to the data storage 210 to determine whether or not the data storage 210 contains the different cluster. This may specifically involve the processor 204referring to a cluster IDs 236 database within data storage 2 ! 0 that lists all existing IDs associated with clusters. With this arrangement, the processor 204 may determine whether or not the data storage 210 contains a cluster ID for a particular cluster that is arranged to contain ROs that correspond to the particular vehicle symptom and to the alternative repair. If the processor 204 determines that the data storage 210 contains the different cluster, the processor 204 may then add the particular RO to this different cluster as discussed above. Whereas, if the processor 204 determines that the data storage 210 does not contain the different cluster, the processor 204 may generate this different cluster and may store this generated different cluster in the data storage 210. Once the processor 204 generated this different cluster, the processor 204 may then add the particular RO to this different cluster as discussed above.

[00135] The processor 204 may generate the different cluster in one of various ways. For instance, the processor 204 may generate a cluster ID for a combination of vehicle attributes (e.g., meta-data of the attributes) that define the cluster. Such attributes may include particular DTC(s), particular symptom(s), particular component(s), and/or particular labor operation(s) (e.g., particular LOC(s)), among others. By way of example, the processor 204 may assign a particular cluster ID to a combination of "P0101, Cleaned, and Mass Airflow Sensor" attributes and may thus associate ROs containing data representative of such attributes with this particular cluster ID. In this manner, different combinations of vehicle attributes may be assigned different cluster IDs. Other examples are also possible.

[00136] Table 8 shows data, identifying two clusters identified with ID 29 through 30, inclusive. Table 8 shows examples of DTC, Action/LOC, and component attributes associated with each respective RO cluster. Of course, as noted above in relation to table 1, Table 8 can be modified to include a separate column for other attributes of an RO cluster as well.

Table 8

[00137] As shown, these example clusters are each arranged to contain ROs that correspond to at least one particular vehicle symptom and to an alternative repair to resolve the at least one particular vehicle symptom . For instance, the cluster having a cluster ID of 29 is associated with a vehicle symptom taking the form of DTC P0104 and with cleaning of an air filter. Whereas, the cluster having a cluster ID of 30 is associated with a vehicle symptom taking the form of DTC P0509 and with LOC C247 for repairing an engine. As such, the above-mentioned different cluster could be one of the example clusters shown in Table 8, among other possible clusters. With this example arrangement, the above-mentioned particular RO could be added to one of the clusters shown in Table 8. For instance, the particular RO may be added to RO cluster ID 30. Other examples are also possible.

[00138] As noted above, the processor 204 could determine that the particular RO includes more than one alternative repair for resolving the particular vehicle symptom. For instance, as noted, the processor 204 may determine that the particular RO includes data indicating at least a first alternative repair and a second alternative repair. In this scenario, adding the particular RO to a different cluster could take various forms. In one case, the processor 204 may arrange the different cluster to contain ROs that correspond to the particular vehicle symptom and to the first and second alternative repairs. In this case, the processor 204 may add the particular RO to this different cluster. In another case, the processor 204 may arrange a first different cluster to contain ROs that correspond to the particular vehicle symptom and to the first alternative repair while arranging a second different cluster to contain ROs that correspond to the particular vehicle symptom and to the second alternative repair. In this case, the processor 204 may add the particular RO to both (or one of) the first and second different clusters. Other cases are also possible.

[00139] Table 9 shows data identifying five clusters identified with ID 31 through 35, inclusive. Table 9 shows examples of DTC, Action(s)/LOC(s), and component attributes associated with each respective RO cluster. Of course, as noted above in relation to table 1, Table 9 can be modified to include a separate column for other attributes of an RO cluster as well.

Table 9

[00140] As shown, these example clusters are each arranged to contain ROs that correspond to at least one particular vehicle symptom and to at least one alteraative repair to resolve the at least one particular vehicle symptom. For instance, the cluster having a cluster ID of 31 is associated with a vehicle symptom taking the form of DTC P0104 and with (i) cleaning of an air filter and (ii) fixing of an engine (e.g., fixing an engine oil leak). Also, the cluster having a cluster ID of 33 is associated with a vehicle symptom taking the form of DTC P0104 and with cleaning of an air filter. Also, the cluster having a cluster ID of 34 is associated with a vehicle symptom taking the form of DTC P0104 and with fixing of an engine. As such, in accordance with the implementations discussed above, an example particular RO could be added to the cluster having the cluster ID of 31 or could be added to one or both of (i) the cluster having the cluster ID of 33 and (ii) the cluster having the cluster ID of 34.

[00141] In another instance, the cluster having a cluster ID of 32 is associated with a vehicle symptom taking the form of DTC P0104 and with (i) cleaning of an engine and (ii) fixing of the engine. Also, the cluster having a cluster ID of 35 is associated with a vehicle symptom taking the form of DTC P0104 and with cleaning of an engine. As such, in accordance with the implementations discussed above, an example particular RO could be added to the cluster having the cluster ID of 32 or could be added to one or both of (i) the cluster having the cluster ID of 34 and (ii) the cluster having the cluster ID of 35. Other instances are also possible IV. SECOND EXAMPLE OPERATION

[00142] Figure 7 is a flowchart illustrating a method 700, according to an example implementation. Method 700 is related to an implementation where (i) the particuiar RO may include data that refers to a particular vehicle symptom and to replacement of a particular vehicle component to resolve the particular vehicle symptom and (ii) the existing cluster may ^¬ be arranged to contain ROs that correspond to the particular vehicle symptom and to the replacement of the particuiar vehicle component for resolving the particular vehicle symptom. This is in contrast to the method 600 where (i) the particular RO may include data that refers to a particular vehicle symptom without necessarily also referring to replacement of a particular vehicle component and (ii) the existing cluster may be arranged to contain ROs that correspond to the particular vehicle symptom without necessarily also corresponding to the replacement of a particular vehicle component to resolve this particular vehicle symptom. Of course, any aspects of the disclosure discussed above in association with method 600 are also applicable in the context of method 700.

Θ0143] At block 702, method 700 involves determining, by at least one processor, that a particular computer-readable vehicle repair order (RO) corresponds to an existing cluster of computer-readable vehicle repair orders (ROs) due to the particular RO including data that refers to a particular vehicle symptom and to replacement of a particular vehicle component for resolving the particular vehicle symptom, where the existing cluster is arranged to contain ROs that correspond to the particuiar vehicle symptom and to the replacement of the particular vehicle component for resolving the particular vehicle symptom. At block 704, method 700 involves, in response to determining that the particular RO corresponds to the existing cluster, the at least one processor determining that the particular RO includes data indicating an alternative repair that defines a vehicle repair for resolving the particular vehicle symptom other than by the replacement of the particular vehicle component. At block 706, method 700 involves, in response to determining that the particular RO includes the data indicating the alternative repair, the at least one processor adding the particular RO to a different cluster of ROs, where the different cluster is arranged to contain ROs that correspond to the particular vehicle symptom, to the replacement of the particular vehicle component, and to the alternative repair.

[00144] In an example implementation, the processor 204 may determine that the particular RO includes data, that refers to a particular vehicle symptom and to replacement of a particular vehicle component to resolve this particular vehicle symptom. Responsively, the processor 204 may determine whether or not the particular RO also includes data referring to at least one alternative repair. In one case, this alternative repair may be a repair to the particular vehicle component at issue such as other than replacing this component. In another case, this alternative repair could be a repair to a component other than the particular vehicle component at issue and this alternative repair could be carried out in addition to replacement of the particular vehicle component at issue. Other cases are also possible.

[00145] In either case, the processor 204 may do so for the reasons noted above and, in this implementation, may also do so for additional reasons. For example, an individual (e.g., a repair technician) using a vehicle repair tool may encounter a vehicle exhibiting the particular vehicle symptom at issue. The individual may evaluate ROs within the existing cluster (or repair hints based on the existing cluster) and could determine that the replacement of the particular vehicle component is a potential repair for resolving the particular vehicle symptom. However, the individual may not be able to determine that an alternative repair should be carried out instead of (or in addition to) the replacement of the particular vehicle component. Thus, the example implementation may allow the processor 204 to essentially figure out at least one alternative repair if such an alternative repair is indeed a possibility. Other examples are also possible.

[00146] Referring again to Table 1, Table 1 shows several examples of clusters that are arranged to contain ROs that correspond to a particular vehicle symptom and to replacement of a particular vehicle component. For instance, the cluster having a cluster ID of 1 is associated with a vehicle symptom taking the form of DTC P0303 and with replacement of an ignition Coil. As such, in this implementation, the existing cluster could be one of the example clusters shown in Table 1, among other possible clusters.

[00147] In accordance with this implementation, if the processor 204 determines that the particular RO includes data, indicating an alternative repair, the processor 204 may add the particular RO to a different cluster. This different cluster may be arranged to contain ROs that correspond to the particular vehicle symptom, to the replacement of the particular vehicle component, and to the alternative repair. In this manner, the particular RO could be appropriately categorized into a cluster that clearly indicates to an individual using a VRT that, to resolve the particular vehicle symptom, an alternative repair is possible instead of (or in addition to) replacement of the particular vehicle component.

[00148] As noted above, the processor 204 could refer to the data storage 210 to determine whether or not the data storage 210 contams the different cluster. If the processor 204 determines that the data storage 210 contains the different cluster, the processor 204 may then add the particular RO to this different cluster as discussed above. Whereas, if the processor 204 determines that the data storage 210 does not contain the different cluster, the processor 204 may generate this different cluster in accordance with this implementation and may store this generated different cluster in the data storage 210. In particular, the processor 204 may generate the different cluster such that the different cluster is arranged to contain ROs that correspond to the particular vehicle symptom, to the replacement of the particular vehicle component, and to the alternative repair. Once the processor 204 generated the different cluster in accordance with this implementation, the processor 204 may then add the particular RO to the different cluster.

[00149] Further, as noted above, the processor 204 could determine that the particular RO includes more than one alternative repair for resolving the particular vehicle symptom. For instance, as noted, the processor 204 may determine that the particular RO includes data indicating at least a first alternative repair and a second alternative repair. In this scenario, adding the particular RO to a different cluster in accordance with this implementation could take various forms. In one case, the processor 204 may arrange the different cluster to contain ROs that correspond to the particular vehicle symptom, to replacement of the particular component, and to the first and second alternative repairs. In tins case, the processor 204 may add the particular RO to this different cluster. In another case, the processor 204 may arrange (i) a first different cluster to contain ROs that correspond to the particular vehicle symptom, to replacement of the particular component, and to the first alternative repair while arranging (ii) a second different cluster to contain ROs that correspond to the particular vehicle symptom., to replacement of the particular component, and to the second alternative repair. In this case, the processor 204 may add the particular RO to both (or one of) the first and second different clusters. Other cases are also possible. V. ADDITIONAL ASPECTS

[00150] In an example implementation, the processor 204 may sometimes determine that the particular RO does not contain data indicating an alternative repair. In response to such a determination, the processor 204 could take one of various actions. For example, if the particular RO is already contained within the existing cluster, the processor 204 may simply keep the particular RO in the existing cluster and/or could generate a report as further discussed below. In another example, if the particular RO is a new RO, the processor 204 could add the particular RO to the existing cluster and/or could generate a report as further discussed below.

[00151] As noted, in response to determining that the particular RO does not contain data indicating an alternative repair, the processor 204 could generate a report for human review. The puipose of the report is to provide valuable information that could help to manually categorize the particular RO into an appropriate cluster. Hence, the report could indicate that the processor 2.04 determined that the particular RO does not contain data indicating an alternative repair. Additionally or alternatively, the report could provide other information that could help appropriately categorize the particular RO. For instance, the processor 204 could identify one or more other ROs within ROs 214 that have similarities to the particular RO at issue. These similarities may involve the other ROs having data indicating the same (or similar) vehicle symptom and/or the same (or similar) replacement of a vehicle component. Upon identifying such ROs, the processor 204 could generate the report to list such ROs and/or perhaps to list valuable information included in these ROs, such as by listing any identified alternative repairs within such ROs for example. Other instances are also possible.

[00152] To illustrate, refer again to Fig. 1 showing that the VRD system 102 may output a report 122. In particular, this report 122 could be displayed as part of a graphical user interface (GUI) on a display of the VRD system. In another case, the VRD system 102 could transmit the report 122 to one or more of the VRTs 106-120 (and/or to other devices) such that a VRT could display this report 122. For instance, VRT 300 of Fig. 300 is shown to display a report 314 (e.g., could be the same as report 122) as part of the user interface 314. In yet another case, the VRD system 102 may store the report 122 in data storage 210 and/or cloud-based data storage so as to make the report 122 accessible for human review via a device (e.g., a VRT). Other cases are also possible.
