BACKGROUND

[0001] Various technologies currently exist for allowing computer users to create electronic documents, to search for electronic documents, and to communicate with other users regarding electronic documents. These activities, however, are typically manually performed and completely separate from one another. Take, for example, a scenario where a user is writing a paper on dinosaurs. In this scenario, the user might utilize a network-based search engine to locate documents having interesting content about dinosaurs. The user might also separately try to locate the author, or authors, of one or more of the identified documents, and attempt to contact them to discuss their work on dinosaurs. Completely separately, the user might utilize a word processing application program to begin writing their paper. Because search, communication, and content creation are completely separate activities, this can be a time-consuming and frustrating process for document creators. Moreover, content located by search engines is often stale, which is also frustrating to users.

[0002] In addition to the inefficiency and frustration caused to users, completely separate search, communication, and content creation can also cause other types of inefficiencies. For example, and without limitation, in very large companies or other types of entities there are often two or more groups of people creating documents on the same topic, many times unbeknownst to one another. This duplication of effort can result in a very inefficient allocation of human resources, particularly at large scale.

[0003] Separate search, communication, and content creation can also result in the inefficient allocation of computing resources. For example, and without limitation, mass storage, memory, and network bandwidth might not be utilized efficiently in scenarios where completely separate search, communication, and content creation results in duplication of effort and inefficient allocation of human resources. For instance, the same or similar content might be duplicated on multiple mass storage devices or in memory. Similarly, inefficient searches might be performed in an attempt to locate document authors or collaborators. These searches can unnecessarily consume network bandwidth and other processing resources.

[0004] It is with respect to these and other considerations that the disclosure made herein is presented. SUMMARY

[0005] Technologies are described herein for document collaboration discovery. Through an implementation of the technologies disclosed herein, aspects of document search, content creation, and collaboration are integrated in a manner that reduces or even eliminates the human resource inefficiencies caused by previous systems wherein these tasks are performed completely separately. Moreover, implementations of the technologies disclosed herein can also reduce the inefficient usage of computing resources, such as mass storage, memory, and network bandwidth, caused by previous systems wherein document search, content creation, and collaboration are separate. Technical benefits other than those specifically identified herein can also be realized through an implementation of the disclosed technologies.

[0006] According to one configuration disclosed herein, a collaborative document authoring environment is provided that allows users to discover, contribute to, and communicate about content that is being actively edited by other users. In particular, the collaborative authoring environment includes a collaboration system that provides functionality for enabling two or more users to collaborate on a document. For example, and without limitation, such users (which might be referred to herein as the "active editors" of a document) can be permitted to create, modify, delete, and/or otherwise edit the same document simultaneously. The collaboration system can also provide functionality for enabling active editors to engage in real-time messaging about a document that is being collaboratively edited. The collaboration system can also provide other types of functionality for enabling multiple active editors to collaboratively author documents.

[0007] In order to utilize the functionality provided by the collaboration system, each active editor can utilize a computing device configured to execute an application, which will be referred to herein as a "collaborative authoring application," for interacting with the functionality provided by the collaboration system. For instance, the collaborative authoring application can provide functionality for editing documents collaboratively, for communicating with other active editors regarding documents that are being edited, and/or other types of functionality.

[0008] In order to enable the functionality presented herein for document collaboration discovery, the collaboration authoring application can also be configured to transmit edits to a document being collaboratively edited to the collaboration system in real or near real time. For example, and without limitation, the collaboration authoring application can transmit words, sentences, paragraphs, or other units of a document being collaboratively edited to the collaboration system as the words, sentences, paragraphs, or other units are created or modified. In turn, the collaboration system can receive the edits to the document in real or near real time and index the edits to update a search index, also in real or near real time. In this manner, the collaboration system can index edits to a document as the edits are made in real or near-real time by the active editors of the document.

[0009] In some configurations, the collaboration system can also obtain metadata about a document being collaboratively edited from the collaboration authoring application, or another source, in real or near real time and index the metadata in the search index. The metadata can include, but is not limited to, data identifying the active editors of a document, data identifying search terms in queries made of the search index that located a document, data identifying previous changes to a document, data identifying one or more previous active editors of the document, and data identifying one or more real-time messaging sessions associated with a document. The collaboration system can also obtain and index, in real or near real time, other types of metadata associated with a document that is being, or has been, collaborative edited in other configurations.

[0010] The collaboration system also provides functionality for discovering documents that other users are currently collaborating on (a process which might be referred to herein as "document collaboration discovery"). For example, and without limitation, the collaboration system can receive a search query that includes one or more search terms from another user. Responsive to receiving the search query, the collaboration system can cause a search to be made of the search index for documents or metadata matching the supplied search terms. The collaboration system can then cause a user interface ("UI") to be presented to the user that includes the results of the search. The UI can include, for instance, the identification of any documents that are currently (i.e. at the time the search query is received) being collaboratively edited. The UI can also identify the active editors of the documents.

[0011] The UI can also include a UI control which, when selected, will cause a request to be transmitted to computing devices associated with the active editors of a document to admit the user that submitted the search query as an active editor of the document. The request can identify the user that submitted the search query and the search terms in the search query that resulted in the document being presented in the search results. This information can be presented to the active editors along with a UI control which, when selected, will admit the user that made the search query as an additional active editor of the document. Similarly, a UI control can be presented which, when selected, will deny the request to join the document as an active editor. If one of the active editors admits the user making the search query as an active editor, the user can be permitted to collaborate on the document in the same manner as the other active editors.

[0012] In some configurations, the UI can also include a UI control which, when selected, will cause a request to be transmitted to computing devices associated with the active editors to admit the user that submitted the search query to a real-time messaging session with one or more of the active editors of the document. The request can also identify the user that submitted the search query and the search terms in the search query that resulted in the document being collaboratively edited being presented in the search results. This information can be presented to the active editors along with a UI control which, when selected, will admit the user that made the search query to a real-time messaging session with one or more active editors of the document. Similarly, a UI control can be presented which will deny the request to join a real-time messaging session about the document.

[0013] If one or more of the active editors indicates that the user making the search query is to be admitted to a real-time messaging session, a real-time messaging session can be established between a computing device associated with the user making the search query and computing devices operated by one or more of the active editors. Alternately, the user making the search request can be admitted to an existing real-time messaging session between two or more of the active editors of the document.

[0025] The following detailed description is directed to technologies for document collaboration discovery. As discussed above, through an implementation of the technologies disclosed herein, aspects of document search, content creation, and collaboration are integrated in a manner designed to reduce or even eliminates the human resource inefficiencies and inefficient use of computing resources caused by previous systems wherein these tasks are performed completely separately. Technical benefits other than those specifically identified herein can also be realized through an implementation of the disclosed technologies.

[0026] While the subject matter described herein is presented in the general context of program modules that execute in conjunction with the execution of an operating system and application programs on a computer system, those skilled in the art will recognize that other implementations can be performed in combination with other types of program modules. Generally, program modules include routines, programs, components, data structures, and other types of structures that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the subject matter described herein can be practiced with other computer system configurations, including hand-held devices, multiprocessor systems, microprocessor-based or programmable consumer electronics, minicomputers, mainframe computers, and the like.

[0027] In the following detailed description, references are made to the accompanying drawings that form a part hereof, and which are shown by way of illustration as specific configurations or examples. Referring now to the drawings, in which like numerals represent like elements throughout the several FIGS., aspects of various technologies for extending a federated graph with third-party data and metadata will be described.

[0028] FIG. 1 is a network and software architecture diagram showing the configuration of a collaborative document authoring environment 100 in which the technologies disclosed herein can be implemented, according to one illustrative configuration. As shown in FIG. 1 , and described briefly above, the collaborative document editing environment 100 includes a collaboration system 102 that provides functionality for enabling two or more users to collaborate on a document 104. For example, and without limitation, such users (which might be referred to herein as the "active editors" 106 A and 106B of the document 104) can be permitted to create, modify, delete, and/or otherwise edit the same document 104 simultaneously. The active editors 106 of a document 104 are users that have the document 104 open for editing in a suitable program.

[0029] The collaboration system 102 can also provide functionality for enabling the active editors 106 to engage in real-time messaging about a document 104 that is being collaboratively edited. In FIG. 1, for example, the users 106A and 106B are participating in a real-time messaging session 118. The collaboration system 102 can also provide other types of functionality for enabling multiple active editors 106 to collaboratively author documents 104.

[0030] In order to utilize the functionality provided by the collaboration system

102, each active editor 106 can utilize a computing device 108 that is configured to execute a collaborative authoring application 110 for interacting with the functionality provided by the collaboration system 102. The computing devices 108 can be, but are not limited to, desktop or laptop computers, smart mobile telephones, tablet devices, slate devices, video game devices, set top boxes, or other types of computing devices capable of connecting to a collaboration system 102 through a network (not shown in FIG. 1).

[0031] The collaborative authoring application 110 can provide functionality for editing a document 104 collaboratively with other active editors 106, for communicating with other active editors 106 regarding a document that is being edited, such as through a real-time messaging session 118, and/or other types of functionality. The document 104 can be a word processing document, a spreadsheet document, a presentation document, a drawing document, the text of a real-time communication session, a user's search history, program source code, or any other type of textual content.

[0032] In order to enable the disclosed functionality, and potentially other types of functionality, the collaboration authoring application 110 can also be configured to transmit edits 112 to a document 104 being collaboratively edited to the collaboration system 102 in real or near real time. For example, and without limitation, the collaboration authoring application 110 can transmit words, sentences, paragraphs, or other units of a document 104 being collaboratively edited to the collaboration system 102 as the words, sentences, paragraphs, or other units are created or modified by the active editors 106. In this manner, edits 112 to a document 104 being collaboratively edited can be transmitted to the collaboration system 102 with little or no human- perceptible lag.

[0033] In turn, the collaboration system 102 can receive the edits 112 to the document 104 in real or near real time, and store the edits 1 12 in an appropriate content store 116. In one configuration, the content store 116 is implemented as a graph that maintains relationships between a document 104, its associated metadata 1 14, edits 1 12 the document, and potentially other types of data. Other implementations can also be utilized in other configurations.

[0034] A search engine 120 operating within or in conjunction with the collaboration system 102 can also index the edits 1 12 to update a search index 122, also in real or near real time. For example, the search engine 120 can index the edits 112 within two seconds from the time the edits 1 12 are received in some configurations. The search index 122 can also be stored in an appropriate data store 124. In this manner, the collaboration system 102 can receive and index edits 1 12 to a document 104 as the edits 112 are made in real or near-real time by the active editors 106 of the document 104.

[0035] In some configurations, the collaboration system 102 can also obtain metadata 114 about a document 104 being collaboratively edited from the collaboration authoring application 110, or another source, in real or near real time. The collaboration system 102 can store the metadata 114 in the content store 1 16 or in another suitable location. The collaboration system 102 can also index the metadata 1 14 in the search index 122 in real or near real time. Referring momentarily to FIG. 2, several illustrative examples of the metadata 1 14 that can be received and indexed by the collaboration system 102 will be described.

[0036] FIG. 2 is a data structure diagram showing aspects of an illustrative data structure that can be utilized to store metadata 114 for use in document collaboration discovery in one particular configuration disclosed herein. As shown in FIG. 2, the metadata 1 14 can include, but is not limited to, metadata 114A identifying the currently active editors 106 of a document 104. The metadata 1 14 can also include metadata 114B identifying the previous active editors 106 of a document 104. The metadata 114 can also include metadata 114C including the contents of one or more real-time messaging sessions 118 associated with a document 104.

[0037] The metadata 1 14 can also include metadata 114D identifying search terms in queries made of the search index 122 that located the document 104. The metadata 114 can also include metadata 114E the specifies the history of users joining the document 104 for collaborative editing and/or joining real-time messaging sessions 118 about the document 104. The metadata 114 can also include metadata 114F identifying previous edits 112 to the document 104. The collaboration system 102 can also obtain and index, in real or near real time, other metadata 114G associated with a document 104 that is being, or has been, collaborative edited in other configurations. For example, the other metadata 114G can provide information about users that searched and located the document 104 such as, but not limited to, other documents 104 that the searching user is working on, other documents 104 that the searching user has recently read, information indicating the location in an organizational hierarchy of the searching user, other information about the searching user, and/or other search terms supplied by the searching user.

[0038] Turning back to FIG. 1, additional details regarding the functionality provided by the collaboration system 102 will be described. In particular, and as discussed briefly above, the search engine 120 also provides functionality for searching the search index 122 to identify documents 104 that are being actively collaborated upon. For example, and without limitation, a user (not shown in FIG. 1) can provide a search query that includes one or more search terms to the search engine 120. The search engine 120 can perform a search for relevant documents 104 using the search index 122. If one or more documents 104 are located that are relevant to the search query, the documents 104 can be identified to the user that submitted the search query in an appropriate UI (also not shown in FIG. 1). The active editors 106 of each relevant document 104 can also be identified in the UI. Additionally, UI controls for requesting to become an active editor 106 (or a reviewer, approver, or observer) of each document 104 and/or for joining a real-time messaging session 118 with one or more of the active editors 106 of each document 104 can also be presented. Additional details regarding these aspects will be provided below with regard to FIGS. 4A-6.

[0039] FIG. 3 is a flow diagram showing aspects of a routine 300 for performing real-time indexing of document edits 112 and associated metadata 114 for use in document collaboration discovery, according to one configuration. It should be appreciated that the logical operations described herein with regard to FIG. 3 and the other FIGS, can be implemented (1) as a sequence of computer implemented acts or program modules running on a computing system and/or (2) as interconnected machine logic circuits or circuit modules within the computing system. [0040] The particular implementation of the technologies disclosed herein is a matter of choice dependent on the performance and other requirements of the computing system. Accordingly, the logical operations described herein are referred to variously as states, operations, structural devices, acts, or modules. These states, operations, structural devices, acts and modules can be implemented in software, in firmware, in special purpose digital logic, and any combination thereof. It should also be appreciated that more or fewer operations can be performed than shown in the FIGS, and described herein. These operations can also be performed in a different order than those described herein.

[0041] The routine 300 begins at operation 302, where the collaboration system

102 enables collaborative document authoring by two or more active editors, such as the active editors 106A and 106B. As discussed above, this functionality includes the ability for each of the active editors 106 to simultaneously edit a document 104 and/or other types of functionality in other configurations. As also discussed above, in in some configurations the collaboration system 102, or another system operating in conjunction therewith, can also provide functionality for enabling real-time messaging between active editors 106. This occurs at operation 304.

[0042] From operation 304, the routine 300 proceeds to operation 306, where the collaboration system 102 determines whether an edit 112 to a document 104 is pending processing. As discussed above, the edits 112 can be transmitted in real or near real time as they are made by the active editors 106. If, at operation 306, the collaboration system 102 determines that an edit 1 12 is pending, the routine 300 proceeds to operation 308 where the edit 112 is received. The routine 300 then proceeds from operation 308 to operation 310, where the edit 112 is stored in the content store 116, or in another suitable location, in the manner described above.

[0043] Once the received edit 1 12 has been stored, the routine 300 proceeds to operation 312, where the search index 122 is updated to reflect the received edit 1 12. Because the edits 1 12 are generally small (e.g. a word, sentence, or paragraph), updating the search index 122 can be performed quickly. In this regard, it is to be appreciated that, in some configurations, the operations 308, 310, and 312 are performed together as a single transaction. In this manner, edits 1 12 can be received, stored, and indexed in real or near real time as the edits 1 12 are made by the active editors 106. From operation 312, the routine 300 proceeds to operation 314, which is described below. [0044] If, at operation 306, the collaboration system 102 determines that an edit

112 is not pending processing, the routine 300 proceeds to operation 314. At operation 314, the collaboration system 102 determines whether a metadata 114 update is pending processing. As discussed above, updates to the metadata 1 14 associated with a document 104 can also be transmitted in real or near real time as changes to the metadata 1 14 are made. If, at operation 314, the collaboration system 102 determines that metadata 114 is pending, the routine 300 proceeds to operation 316 where the metadata 114 is received. The routine 300 then proceeds from operation 316 to operation 318, where the metadata 1 14 is stored in the content store 1 16, or in another suitable location, in the manner described above.

[0045] Once the metadata 1 14 has been stored in the content store 116, the routine 300 proceeds to operation 320, where the search index 122 is updated to reflect the received metadata 1 14. Because changes to the metadata 1 14 are also generally small, updating the search index 122 to reflect changes to the metadata 1 14 for a document 104 can also be performed quickly. As with the processing of the edits 112, the operations 316, 318, and 320 can be performed together as a single transaction. In this manner, updates to the metadata 114 can be received, stored, and indexed in real or near real time as the metadata 114 is changed. From operation 320, the routine 300 proceeds back to operation 302, where additional edits 1 12 and metadata 114 can be processed in a similar manner.

[0046] FIGS. 4A-4B are network and software architecture diagrams showing additional aspects of the collaborative document authoring environment 100 shown in FIG. 1 and described above, which is configured to provide functionality for document collaboration discovery. As shown in FIG. 4A, and described briefly above, the collaboration system 102 also provides functionality for discovering documents 104 that other users (i.e. the active editors 106) are actively collaborating on (a process which might be referred to herein as "document collaboration discovery").

[0047] For example, and without limitation, the search engine 120 that operates in conjunction with the collaboration system 102 can receive a search query 402 that includes one or more search terms. In the example shown in FIG. 4A, for instance, a user 400 has utilized a computing device 108C executing the collaborative authoring application 110 to submit a search query 402 to the search engine 120.

[0048] Responsive to receiving the search query 402, the search engine 120 performs a search of the search index 122 for documents 104 or metadata 114 matching the supplied search terms. The collaboration system 102 can then cause a UI to be presented to the user 400 that includes the search results 404. The UI can include, for instance, the identification of any documents 104 that are currently (i.e. at the time the search query 402 is received being collaboratively edited. The UI can also identify the active editors 106 of the documents identified documents 104. In one configuration, the UI is presented by the collaborative authoring application 110. The UI can be presented by other components in other configurations. In this regard, it is to be appreciated that search results 404 might not be presented, or might be truncated, to a user 400 that is not authorized to view the search results 404.

[0049] The UI presented by the collaborative authoring application 110 can also include a UI control (not shown in FIGS. 4A or 4B) which, when selected, will cause a request 406 to be transmitted to computing devices 108 associated with the active editors 106 of a document 104 to admit the user 400 that submitted the search query 402 as an active editor of the document 104. The request 406 can identify the user 400 that submitted the search query 402 and the search terms in the search query 402 that resulted in the document 104 being presented in the search results 404.

[0050] This information can be presented to the active editors 106 along with a

UI control which, when selected, will admit the user 400 that made the search query 402 as an additional active editor 106 of the document 104. Similarly, a UI control can be presented to the active editors 106 which, when selected, will deny the request 406 to join the document 104 as an active editor 106. If one of the active editors 106 admits the user 400 making the search query 402 as an active editor 106, the user 400 can be permitted to collaborate on the document 104 in the same manner as the other active editors 106.

[0051] In some configurations, the UI presented to the user 400 that submitted the search query 402 can also include a UI control (not shown in FIGS. 4 A or 4B) which, when selected, will cause a request 408 (shown in FIG. 4B) to be transmitted to computing devices 108 associated with the active editors 106 to admit the user 400 that submitted the search query 402 to a real-time messaging session 118 with one or more of the active editors 106 of the document. The request 408 can also identify the user 400 that submitted the search query 402 and the search terms in the search query 402 that resulted in the document 104 being collaboratively edited being presented in the search results 404. This information can be presented to the active editors 106 along with a UI control which, when selected, will admit the user 400 that made the search query 402 to a real-time messaging session 118 with one or more active editors 106 of the document 104. Similarly, a UI control can be presented which will deny the request 408 from the user 400 to join a real-time messaging session about the document 104.

[0052] If one or more of the active editors 106 admits the user 400 making the search query 402 to a real-time messaging session 118, a real-time messaging session 118 can be established between the user 400 making the search query 402 and one or more of the active editors 106. Alternately, the user 400 making the search request 402 can be admitted to an existing real-time messaging session 118 between two or more of the active editors 106 of the document 104. Additional details regarding several illustrative UIs for presenting the search results 404 will be provided below with regard to FIGS. 5A and 5C. Additional details regarding one illustrative UI for presenting the request 406 to join the collaborative authoring session 406 will be described below with regard to FIG. 5B.

[0053] FIGS. 5A-5C are user interface diagrams showing several illustrative

UIs 500, 525, and 575, respectively, that can be provided for use in document collaboration discovery, according to various configurations disclosed herein. In particular, FIG. 5 A shows a UI 500 that can be presented by the collaborative authoring application 110 to a user 400 that desires to discover documents 104 that are being actively collaborated upon. In this example, the UI 500 includes a search field 502 in which the user 400 can specify one or more search terms 402. In this example, the user 400 has specified the word "dinosaur" as a search term 402.

[0054] The UI 500 also includes a list of search results 404. Each of the items

504 in the list of search results 404 corresponds to a document 104 that is being actively edited by two or more active editors 106 at the time that the search terms 402 are received. The UI 500 also includes identifiers 506 for each of the documents 104 returned by the search. For example, the identifier 506A for the item 504A lists a document named "DINOSAUR RESEARCH.DOCX" and the identifier 506B for the item 504B lists a document named "DINOSAUR PRESENT ATION.PPTX."

[0055] The UI 500 also includes identifiers 508 for the active editors 106 of each document referenced in the search results 404. For instance, in the example shown in FIG. 5 A, the indicator 508A indicates that two active editors 106 (i.e. Joseph Kearney and Adam Webb) are collaboratively editing the document 104 entitled "DINOSAUR RESEARCH.DOCX." Similarly, the indicator 508B indicates that three active editors 106 (i.e. Bill Nelson, Steven Wong, and Suzanne Choi) are collaboratively editing the document 104 entitled

"DINOSAUR PRESENTATION.PPTX."

[0056] As described briefly above, the UI 500 presented by the collaborative authoring application 110 can also include UI controls 510 which, when selected, will cause a request 406 to be transmitted to computing devices 108 associated with the active editors 106 of a document 104 to admit the user 400 that submitted the search query 402 as an active editor of the document 104. In the example shown in FIG. 5 A, for instance, the UI control 510A can be selected using the mouse cursor 514, for instance, to cause a request 406 to be transmitted to the users "Joseph Kearney" and "Adam Webb" to join in the collaborative editing of the document 104 entitled "DINOSAUR RESEARCH.DOCX." Similarly, the UI control 510B can be selected to cause a request 406 to be transmitted to the users Bill Nelson, Steven Wong, and Suzanne Choi, to join in the collaborative editing of the document 104 entitled "DINOSAUR PRESENTATION.PPTX."

[0057] In some configurations, the UI 500 presented to the user 400 that submitted the search query 402 can also include UI control 512 which, when selected, will cause a request 408 (shown in FIG. 4B) to be transmitted to computing devices 108 associated with the active editors 106 to admit the user 400 that submitted the search query 402 to a real-time messaging session 118 with one or more of the active editors 106 of the document. In the example shown in FIG. 5 A, for instance, the UI control 512A can be selected to cause a request 408 to be transmitted to the users "Joseph Kearney" and "Adam Webb" to join in a real-time messaging session 118 regarding the document 104 entitled "DINOSAUR RESEARCH.DOCX." Similarly, the UI control 512B can be selected to cause a request 408 to be transmitted to the users Bill Nelson, Steven Wong, and Suzanne Choi, to j oin in a real-time messaging session 118 regarding the document 104 entitled "DINOSAUR PRESENTATION.PPTX."

[0058] FIG. 5B shows a UI 525 that can be presented to the active editors 106 by the collaborative authoring application 110 following the selection of one of the UI controls 510 for requesting to join a document 104 as an active editor 106. As shown in FIG. 5B, a dialog box 516 or other type of UI control can be presented to the active editors 106 indicating that a user 400 (in this example, a user 400 named "Steve Smith") has requested to join the document 104 as an active editor 104. The dialog box 516 or other type of UI control can also identify the search terms that led the user 400 to the document 104. In this example, the user 400 searched for "dinosaurs," which located the document entitled "DINOSAUR RESEARCH.DOCX." Through the presentation of this information, the active editors 106 can learn the identity of the user 400 that is requesting to become an active editor 106 and the search terms that led the user 400 to the document 104.

[0059] As shown in FIG. 5 A, the UI 525 can also include UI controls 518A and

518B which, when selected, will allow the request 406 or deny the request 406, respectively. In this example, an active editor 106 has selected the UI control 518A with the mouse cursor 514 in order to allow the user 400 to become an active editor 104 of the document entitled "DINOSAUR RESEARCH.DOCX." It should be appreciated that a similar UI can also be presented when a user 400 makes a request 408 to join a real-time messaging session 118 with active editors 106 of a document 104.

[0060] It should be further appreciated that the user interface 525 can also include other information that might be helpful to the active editors 106 in determining whether to admit the requesting user 400 to a collaborative editing or real-time messaging session 118. For example, and without limitation, the UI 525 might include information indicating the relationship between the requesting user 400 and the active editor 106 within an organization. For instance, a portion of an organizational chart might be presented in the UI 525. In another configuration, the UI 525 might indicate whether the user 400 is a member of an active editor's contact list or social network. The UI 525 might also indicate other documents that the user 400 has authored, biographic information about the user 400, a photo or video of the user 400, and/or contact information for the user 400, such as their email address, phone number, office location. Other types of information can be presented in other configurations.

[0061] FIG. 5C shows another example UI 575 that can be presented to a user

400 of the collaborative editing application 110. In this example, the user 400 is editing text 580 of a document. The collaborative editing application 110 examines the text 580 being edited and automatically performs searches using terms 582 located in the text 580. If relevant search results 404 are returned by the searches, the search results 404 can be presented in the search pane 584.

[0062] For instance, in the example shown in FIG. 5C, the term 'dinosaurs' was located in the text 582 and utilized to generate a search query 402 to the search engine 120. Because relevant search results 404 were returned by the search, the terms 582 can be underlined or otherwise emphasized to indicate that documents 104 relating to the terms 582 are being actively collaborated upon. Additionally, the search results 404 are shown in the search pane 584 including, for each relevant document 104, the name of the document, the active authors, and UI controls 510 and 512 for requesting to join the document 104 as an active editor 106 and to join a real-time messaging session 1 18 about the document 104.

[0063] It should be appreciated that other UI controls and information can also be presented in other configurations. For example, and without limitation, in one configuration a user 400 can specify a "standing query." As standing query is a query that is automatically performed periodically. The results of the search can be presented to the user continually or when new documents 104 are identified that match the terms specified in the standing query. Other types of searches can be performed in other configurations.

[0064] FIG. 6 is a flow diagram showing aspects of a routine 600 for performing document collaboration discovery, according to one configuration. The routine 600 begins at operation 602, where the search engine 120 receives a search query 402 including one or more search terms. In some configurations, the user 400 providing the search query 402 can indicate that only documents 104 that have been actively editing in a previous timeframe (e.g. the last 15 minutes) are to be returned by the search query 402. The user 400 can also define other aspects of the manner in which the search query 402 is to be performed in other configurations.

[0065] The routine 600 then proceeds from operation 602 to operation 604, where the search engine 120 performs a search of the search index 122 utilizing the search terms. If relevant search results 404 are returned by the search, the routine 600 proceeds from operation 606 to operation 608.

[0066] At operation 608, the list of search results 404 is presented in an appropriate UI, such as the illustrative UIs 500 and 575 shown in FIGS. 5A and 5C, respectively. In this regard, it is to be appreciated that the search results 404 can be ranked based upon their relevance in various configurations. The relevance of a particular search result can be determined, at least in part, based upon the metadata 1 14 associated with the search result. For example, and without limitation, recent document joins and subsequent edits by users can cause the relevance of a particular search result to rise. The relevance of a particular document 104 in the search results 404 can be further influenced based upon how often the document 104 is appearing in the search results 404, how often users 400 are requesting to collaborate on a document 104 in the search results 404, the active editors 106 that are currently editing a document 104 in the search results 404 and their relationship to the searcher, the previous active editors 106 of a document 104 in the search results 404, and/or other factors or metadata 1 14.

[0067] The routine 600 then proceeds from operation 608 to operation 610, where the collaboration system 102 determines whether a request 406 has been received from the user 400 to join a document 104 identified in the search results 404 as an active editor 106. If such a request has been received, the current active editors 106 of the document 104 are queried to admit the user 400 as an active editor 106. As discussed above, a UI 525, discussed above with regard to FIG. 5B, can be presented to the current active editors 106 to obtain their consent to add the user 400 as an active editor 106.

[0068] If one or more of the active editors 106 approves the request 406, the routine 600 proceeds from operation 614 to operation 616, where the user 400 is admitted to the document 104 as an active editor 106. If the request 406 is declined, the routine 600 proceeds from operation 614 to operation 618. In this regard, it is to be appreciated that, in some configurations, an active editor 106 does not need to provide approval before the user 400 is admitted as an active editor 106 of the document 104. In these configurations, the user 400 is automatically admitted to the document 104 as an active editor 106.

[0069] At operation 618, the collaboration system 102 determines whether a request 408 has been received from the user 400 to join a real-time messaging session 118 regarding a document 104 identified in the search results 40. If such a request has been received, the current active editors 106 of the document 104 are queried to admit the user 400 to the real-time messaging session 1 18.

[0070] If one or more of the active editors 106 approves the request 408, the routine 600 proceeds from operation 618 to operation 620, where the user 400 is admitted to the real-time messaging session 1 18. If the request 408 is declined, the routine 600 proceeds from operation 618 back to operation 602, where additional search queries 402 can be processed in the manner described above. In this regard, it is to be appreciated that, in some configurations, an active editor 106 does not need to provide approval before the user 400 is admitted to a real-time messaging session 1 18 with one or more of the active editors 106 of the document 104. In these configurations, the user 400 is automatically admitted to the real-time messaging session 1 18.

[0071] It should be appreciated that the various software components described above executing on the computing devices 108 and within the collaboration system 102 can be implemented using or in conjunction with binary executable files, dynamically linked libraries ("DLLs"), application programming interfaces ("APIs"), network services, script files, interpreted program code, software containers, object files, bytecode suitable for just-in-time ("JIT") compilation, and/or other types of program code that can be executed by a processor to perform the operations described herein with regard to FIGS. 1-6. Other types of software components not specifically mentioned herein can also be utilized.

[0072] FIG. 7 is a computer architecture diagram that shows an architecture for a computer 700 capable of executing the software components described herein. The architecture illustrated in FIG. 7 is an architecture for a server computer, mobile phone, e-reader, smart phone, desktop computer, netbook computer, tablet computer, laptop computer, or another type of computing device suitable for executing the software components presented herein.

[0073] In this regard, it should be appreciated that the computer 700 shown in

[0074] The computer 700 illustrated in FIG. 7 includes a central processing unit 702 ("CPU"), a system memory 704, including a random access memory 706 ("RAM") and a read-only memory ("ROM") 708, and a system bus 710 that couples the memory 704 to the CPU 702. A basic input/output system containing the basic routines that help to transfer information between elements within the computer 700, such as during startup, is stored in the ROM 708. The computer 700 further includes a mass storage device 712 for storing an operating system 714 and one or more programs including, but not limited to the collaborative authoring application 110, the search engine 120, and/or the search index 122 depending upon the use of the computer 700. The mass storage device 712 can also be configured to store other types of programs and data described herein but not specifically shown in FIG. 7.

[0075] The mass storage device 712 is connected to the CPU 702 through a mass storage controller (not shown) connected to the bus 710. The mass storage device 712 and its associated computer readable media provide non-volatile storage for the computer 700. Although the description of computer readable media contained herein refers to a mass storage device, such as a hard disk, CD-ROM drive, DVD-ROM drive, or USB storage key, it should be appreciated by those skilled in the art that computer readable media can be any available computer storage media or communication media that can be accessed by the computer 700.

[0076] Communication media includes computer readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave or other transport mechanism and includes any delivery media. The term "modulated data signal" means a signal that has one or more of its characteristics changed or set in a manner as to encode information in the signal. By way of example, and not limitation, communication media includes wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, radio frequency, infrared and other wireless media. Combinations of the any of the above should also be included within the scope of computer readable media.

[0077] By way of example, and not limitation, computer storage media can include volatile and non-volatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. For example, computer storage media includes, but is not limited to, RAM, ROM, EPROM, EEPROM, flash memory or other solid state memory devices, CD-ROM, digital versatile disks ("DVD"), HD-DVD, BLU-RAY, or other optical storage disks, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to store the desired information and which can be accessed by the computer 700. For purposes of the claims, the phrase "computer storage medium," and variations thereof, does not include waves or signals per se or communication media.

[0078] According to various configurations, the computer 700 can operate in a networked environment using logical connections to remote computers through a network such as the network 718. The computer 700 can connect to the network 718 through a network interface unit 720 connected to the bus 710. It should be appreciated that the network interface unit 720 can also be utilized to connect to other types of networks and remote computer systems. The computer 700 can also include an input/output controller 716 for receiving and processing input from a number of other devices, including a keyboard, mouse, touch input, or electronic stylus (not shown in FIG. 7). Similarly, the input/output controller 716 can provide output to a display screen, a printer, or other type of output device (also not shown in FIG. 7).

[0079] It should be appreciated that the software components described herein, such as but not limited to the collaborative authoring application 110, can, when loaded into the CPU 702 and executed, transform the CPU 702 and the overall computer 700 from a general-purpose computing system into a special-purpose computing system customized to facilitate the functionality presented herein. The CPU 702 can be constructed from any number of transistors or other discrete circuit elements, which can individually or collectively assume any number of states. More specifically, the CPU 702 can operate as a finite-state machine, in response to executable instructions contained within the software modules disclosed herein, such as but not limited to the collaborative authoring application 110. These computer-executable instructions can transform the CPU 702 by specifying how the CPU 702 transitions between states, thereby transforming the transistors or other discrete hardware elements constituting the CPU 702.

[0080] Encoding the software modules presented herein, such as the collaborative authoring application 110, can also transform the physical structure of the computer readable media presented herein. The specific transformation of physical structure depends on various factors, in different implementations of this description. Examples of such factors include, but are not limited to, the technology used to implement the computer readable media, whether the computer readable media is characterized as primary or secondary storage, and the like. For example, if the computer readable media is implemented as semiconductor-based memory, the software disclosed herein can be encoded on the computer readable media by transforming the physical state of the semiconductor memory. For instance, the software can transform the state of transistors, capacitors, or other discrete circuit elements constituting the semiconductor memory. The software can also transform the physical state of such components in order to store data thereupon.

[0081] As another example, the computer readable media disclosed herein can be implemented using magnetic or optical technology. In such implementations, the software components presented herein can transform the physical state of magnetic or optical media, when the software is encoded therein. These transformations can include altering the magnetic characteristics of particular locations within given magnetic media. These transformations can also include altering the physical features or characteristics of particular locations within given optical media, to change the optical characteristics of those locations. Other transformations of physical media are possible without departing from the scope and spirit of the present description, with the foregoing examples provided only to facilitate this discussion.

[0082] In light of the above, it should be appreciated that many types of physical transformations take place in the computer 700 in order to store and execute the software components presented herein. It should also be appreciated that the architecture shown in FIG. 7 for the computer 700, or a similar architecture, can be utilized to implement other types of computing devices, including hand-held computers, embedded computer systems, mobile devices such as smartphones and tablets, and other types of computing devices known to those skilled in the art.
