The implementation details of the technical scheme of the embodiment of the present application are described in detail below:

Fig. 2 schematically shows a flowchart of a database generation method according to an embodiment of the present application. An executing subject of the database generation method may be a server, such as the client 101 shown in Fig. 1.

Referring to Fig. 2, the database generation method at least includes steps S210 to S240, which are described in detail as follows.

At step S210, an image of a Chinese character is acquired.

In one embodiment of the present application, characters may be English words, Chinese characters, Mongolian characters, etc.

In one embodiment of the present application, the image of the Chinese character may be acquired by a terminal which executes the database generation method, or transmitted to the terminal which executes the database generation method after being acquired by other terminals. The acquisition method may be photo taking, optical character recognition, etc.

In step S220, based on the image of the Chinese character, elementary components contained in the Chinese character are determined, and positions of the elementary components in the image of the Chinese character are determined.

In one embodiment of the present application, the image of the Chinese character may be segmented to obtain a plurality of Chinese character image segments; elementary components corresponding to the Chinese character image segments are identified; and the elementary components corresponding to the plurality of Chinese character image segments are taken as the elementary components contained in the Chinese character. In one embodiment of the present application, segmentation may be conducted based on the continuity between strokes in the image. In a further embodiment of the present application, segmentation may be conducted according to the radicals of the Chinese character.

In one embodiment of the present application, elementary components contained in the image segments may be taken as elementary components corresponding to the Chinese character image segments, that is, the elementary components may be identified based on the continuity between strokes. In a further embodiment of the present application, the elementary components may be radicals, and radicals contained in the image segments may be taken as elementary components corresponding to the Chinese character image segments.

In one embodiment of the present application, a position of an elementary component in the image of the Chinese character may be determined according to a position of an image segment in the image of the Chinese character, for example, when an image segment is at the first position from the left, it can be determined that the position of the elementary component corresponding to the image segment is left-top.

In one embodiment of the present application, a position of an elementary component in the image of the Chinese character may be determined according to a position of an image segment in the image of the Chinese character and the number of image segments at each position, for example, if there are three image segments on the left of the image of the Chinese character, the position of the elementary component at the second position from the left is leftcenter; and if there are four image segments on the left of the image of the Chinese character, the position of the elementary component at the second position from the left is left-top-center.

Referring to Fig. 2 still, in step S230, position codes corresponding to the positions of the elementary components are determined.

In one embodiment of the present application, the position codes corresponding to the positions of the elementary components may be preset manually.

In one embodiment of the present application, a position map corresponding to the Chinese character may be determined based on the positions of the elementary components in the image of the Chinese character, the position map containing a plurality of structural positions, and the position codes being provided corresponding to the structural positions in the position map; structural positions of the elementary components in the position map are determined based on the positions of the elementary components in the image of the Chinese character; and the position codes of the structural positions corresponding to the elementary components are taken as the position codes of the positions corresponding to the elementary components.

In one embodiment of the present application, a map code of the position map may also be determined before determining the position map corresponding to the Chinese character; distinguishing codes of the position map for distinguishing the structural positions are determined; and the map code is combined with the distinguishing codes corresponding to the structural positions to obtain the position codes corresponding to the structural positions.

In one embodiment of the present application, the position map may be a square array diagram, the number of rows or columns of the square array may be acquired, and the map code is obtained by subtracting one from the number of rows or columns. For example, if the position map is a square array with 2 rows and 2 columns, the map code may be 1; and if the position map is a square array with 4 rows and 4 columns, the map code may be 3. In one embodiment of the present application, the structural positions may be encoded with letters according to a sequence of the structural positions as the distinguishing codes of the structural positions. For example, from left to right, the structural positions are encoded row by row with letters a, b, c, d, etc. as the distinguishing codes of the structural positions. Then, the position codes obtained by combining the map code with the distinguishing codes are: la, lb, 1c, Id or 4a, 4b, 4c, 4d ... 4y, as shown in Figs. 3-7, which schematically show position maps according to an embodiment of the present application.

In step S240, the elementary components and their corresponding position codes are stored in a corresponding manner to obtain a component library of a database.

In one embodiment of the present application, a structure of the Chinese character may be acquired, such as a left-right structure, a front-back structure, a front-center-back structure and a top-bottom structure, and then the structure of the Chinese character is stored in a structure library of the database; and the Chinese character is stored in a Chinese character library of the database.

In one embodiment of the present application, the structure of the Chinese character may be determined based on the positions of the elementary components.

In the embodiment shown in Fig. 2, by acquiring an image of a Chinese character; determining, based on the image of the Chinese character, elementary components contained in the Chinese character and positions of the elementary components in the image of the Chinese character; determining position codes corresponding to the positions of the elementary components; and storing the elementary components and their corresponding position codes in a corresponding manner to obtain a component library of a database, the components can be stored in a computer and retrieved through the codes, so that the database can be automatically generated without manual entry, which reduces the difficulty of generating the database.

In one embodiment of the present application, further, a target stroke may be acquired, candidate components containing the target stroke are retrieved from a component library, and the candidate components are displayed; in response to a component selection instruction to select a target component from the candidate components, the target component is displayed, and at least one position selection button for selecting a position of the target component is displayed; in response to a position selection instruction to select the position of the target component received through the at least one position selection button, a target structure containing the position of the target component is retrieved from the structure library, candidate characters having the target structure and with the target component at the position of the target component are retrieved from the Chinese character library, and the candidate characters are displayed; and in response to a character selection instruction to select from the candidate characters a character to be retrieved, the character to be retrieved is retrieved, as shown in Fig. 8, which schematically shows a diagram of a character retrieval interface according to an embodiment of the present application.

In one embodiment of the present application, the target stroke may be input by the user in the client 101, for example, the target stroke may be input by handwriting. The component may be the same as the stroke or a combination of multiple strokes. The component may be determined based on continuity, that is, strokes connected together may be determined as one component, so that users can easily use the method even if without having a good knowledge of radicals. In a further embodiment of the present application, the component may be a radical.

In one embodiment of the present application, in response to a retrieval instruction, basic strokes may be acquired and displayed; and in response to a stroke selection instruction to select the target stroke from the basic strokes, the target stroke is acquired, and search is conducted in the component library by using position codes corresponding to the candidate components containing the target stroke to obtain the candidate components containing the target stroke; and the candidate components are displayed. The retrieval instruction may be input in an interface shown in Fig. 9 which schematically shows a diagram of terminal interface switching involved in a character retrieval method according to an embodiment of the present application. By tapping the GAMES button in the left figure of Fig. 9 which becomes darker after being selected, the interface in the right figure of Fig. 9 is presented, which confirms that the user has input the retrieval instruction.

In one embodiment of the present application, the basic strokes may be preset. For example, when the character to be retrieved is a Chinese character, the basic strokes may include: a dot stroke ( ' ), a horizontal stroke (^), a vertical stroke ( I ), a left-falling stroke ( J ), a right-falling stroke ( ), a rising stroke ( ), etc. In a further embodiment of the present application, the preset basic strokes may alternatively be a dot stroke ( ' ), a horizontal stroke ( ^), a vertical stroke ( I ) or a vertical-J hook stroke ( J ), a left-falling stroke ( J ), and a horizontal-J hook stroke (^).

In one embodiment of the present application, the target stroke and the basic strokes may be identified from the character to be retrieved.

In one embodiment of the present application, a Chinese character image of the character to be retrieved may be acquired; segment the Chinese character image to obtain a plurality of image segments; acquire a stroke in each image segment at a given position; and the basic strokes are determined based on the strokes at the given positions, wherein the position may include: the whole image, top, bottom, left, right, center, outside, left-top, right-top, left-bottom and right-bottom.

In one embodiment of the present application, the character may be segmented based on the continuity between strokes. The stroke at the left-top, left or top of the image segment may be taken as the stroke at the given position. Stroke acquisition may be conducted in the order of left-top, left and top. That is, the stroke at the left-top may be acquired first; if the acquisition fails, the stroke at the left is to be acquired; and if the acquisition fails, the stroke at the top is to be acquired. The strokes in the image segments at the given positions may be taken as the basic strokes. In a further embodiment of the present application, a starting stroke in an image segment at a given image position in the Chinese character image and preset strokes related to the starting stroke may be taken as the basic strokes. For example, when the starting stroke in the segment image at the given image position in the Chinese character image is a horizontal stroke (^), the preset strokes related to the starting stroke may include: a dot stroke ( ' ), a vertical stroke ( I ) or a vertical-J hook stroke ( J ), a left-falling stroke ( J ), and a horizontal- J hook stroke (^).

In one embodiment of the present application, the basic strokes may be displayed in a stroke display page to prompt the user to select the target stroke from the basic strokes. The basic strokes displayed in the stroke display page may be changeable. If a stroke change instruction instead of the stroke selection instruction is received, the basic strokes can be replaced with alternative basic strokes. The stroke change instruction may be to swipe horizontally or vertically on the page.

In one embodiment of the present application, the candidate components may be retrieved in response to the stroke selection instruction received through the stroke display page; and the stroke selection page may be switched to the component selection page, the candidate components are displayed in the component selection page, and the user is prompted to finish stroke selection and start component selection through the page switching. The candidate components in the component selection page may also be changeable, so that all candidate components in one component selection page can be displayed. The candidate components may be changed in response to a component change instruction.

In one embodiment of the present application, candidate components with the target stroke as the starting stroke may be retrieved. In this way, the number of components acquired may be greatly reduced compared with acquiring all components containing the target stroke, so that the selection of the target component can be accelerated.

In one embodiment of the present application, a position of the target stroke in the candidate component may be selected, so as to determine the candidate component according to both the target stroke and the position of the target stroke.

In one embodiment of the present application, if no candidate component is found, the target stroke is taken as the character to be retrieved; and if no candidate character is found, the target component is taken as the character to be retrieved.

In one embodiment of the present application, in response to the component selection instruction received through the component selection page, the component selection page may be switched to a character selection page, so that the user is prompted to select characters through the page switching, and the target component and the position selection buttons are displayed in the character selection page.

In one embodiment of the present application, when switching to the character selection page, the position selection buttons which receive a selected preset position may be set at the same time; when displaying the character selection page, the preset position may be acquired, preset characters with the target component at the preset position are retrieved, and the preset characters are displayed in the character selection page; and in response to the position selection instruction to select the target position at the position selection buttons, the candidate characters with the target component at the target position are retrieved, and in the character selection page, the preset characters are replaced with the candidate characters.

In one embodiment of the present application, there may be more than one position selection button; after acquiring the preset position, one or more position selection buttons corresponding to the preset position may be marked in the character selection page; and after acquiring the position selection instruction, the one or more position selection buttons corresponding to the preset position are unmarked in the character selection page, and one or more position selection buttons corresponding to the position selection instruction are marked. Marking may be realized by differentiated display, for example, the marked button may be highlighted.

In one embodiment of the present application, one or more position selection buttons selected in the character selection page according to the position selection instruction may be acquired as the one or more position selection buttons corresponding to the position selection instruction; and a position of the one or more position selection buttons corresponding to the position selection instruction in the plurality of position selection buttons may be acquired as the target position, for example, when a button located at the “top” in the plurality of position selection buttons is selected, the target position may be determined as “top”.

In one embodiment of the present application, the number of the position selection buttons is at least nine, and the position selection buttons are arranged into a square array. For example, when there are nine position selection buttons, the nine position selection buttons are arranged into a 3x3 square array to represent “inside”, “center” and “outside”. In this way, many positions may be represented.

In one embodiment of the present application, the target position may be acquired by fuzzy matching. If there are nine position selection buttons, when the position selection buttons in the first column from the left are selected, the target position may be left or left-center, so that more potential candidate characters may be acquired.

In one embodiment of the present application, if a stroke adding instruction is received, retrieve next candidate strokes in the same component as the target stroke, and display the next candidate strokes; in response to a next stroke selection instruction to select a next target stroke from the next candidate strokes, acquire the next target stroke, and retrieve candidate components containing the target stroke and the next target stroke; and the target stroke and the next target stroke are displayed, and the candidate components containing the target stroke and the next target stroke are displayed, which further reduces the number of the candidate components acquired, thus accelerating the retrieval speed.

In one embodiment of the present application, before responding to the next stroke selection instruction, in response to the stroke adding instruction received through a stroke adding button, the target stroke may be moved away from a reserved position for displaying the next target stroke in a stroke display area; in response to the next stroke selection instruction, the target stroke is displayed in the stroke display area, and the next target stroke is displayed at the reserved position in the stroke display area, so that strokes in the stroke display area can be displayed at proper positions, for example, when there is only the target stroke in a stroke selection area, the target stroke may be located in the center of the stroke display area; and when responding to the next stroke selection instruction, the target stroke is moved from the center to one side, such as the left side, and half of the stroke display area of another layer is taken as the reserved position of the next target stroke, and so on, in response to each stroke adding instruction, one stroke may be added, and the strokes are arranged in the stroke display area according to a stroke selection order, so that the user can quickly retrieve the character.

In one embodiment of the present application, if a component adding instruction is received, acquire a target stroke of a next component, retrieve next candidate components containing the target stroke of the next component, and display the next candidate components; in response to a component selection instruction to select a next target component from the next candidate components, display the next target component, and display at least one position selection button for selecting a position of the next target component; and in response to a position selection instruction to select the position of the next target component received through the at least one position selection button, acquire a next target position corresponding to the position selection instruction, retrieve candidate characters with the target component at the target position and the next target component at the next target position, and display the candidate characters, wherein for the process of retrieving the next target component, one can refer to the process of retrieving the target component.
