Description

  The present invention relates to a search processing technique for data shared by a plurality of users.

  A data sharing system that stores and shares various electronic information is known. In particular, there is known a data sharing system in which each registered user freely registers data through a network and freely browses data registered in a database.

  In such a data sharing system, various types of information are accumulated, and information classification management is required.

  As one of the conventional methods, a method of managing shared data by classifying shared data into folders is known. In this method, a folder for each field (classification destination folder) is created in advance in the data sharing system, and at the time of data registration, the user selects a folder that is considered most applicable in terms of data (for example, a data file). , Data storage locations (URL), etc.) are accumulated, and when browsing the data, the user narrows down the data search range by designating a folder, and preferentially displays data that is likely to be desired. Furthermore, when there are a large number of folders, the classification destination folders are managed in a hierarchy.

  However, if the data is classified from a plurality of viewpoints, there are often a plurality of folders corresponding to the registration destination. The folder that is selected as the most suitable for data registration is often different from the folder that is searched from the viewpoint according to the purpose and application of data use. If multiple users share data, register the data. Since the user who used the system is often different from the user who used it, it was difficult to determine the folder in which the data was registered.

  If the desired data is not found, the user thinks that the necessary data is not registered and registers the same data in duplicate, which is wasteful in terms of work labor and resource utilization. There was a problem that occurred.

  In order to solve these problems, in order to be able to classify the data into multiple classification destinations, when the data is registered by adding the tag selected by the user from a predetermined tag group to the data and searching for the data There is known a system for searching using a tag.

  In addition, a system is known that stores data tagged with each user and displays the number of users who have registered data with the same tag as that data when the user displays his registered data. .

  FIG. 1 is a diagram showing a block configuration example of a data search apparatus according to an embodiment of the present invention.

  The data search device 1 is realized by a computer system including hardware having a CPU, a memory, and the like, and a software program.

  The data search device 1 includes a tag item storage unit 11, a tag matrix editing unit 12, a tag matrix storage unit 13, an item count totaling unit 14, a tag matrix output unit 15, an item output unit 16, a display log storage unit 17, and a tag editing unit The unit 18 is provided.

  The data search device 1 includes an input device 2 and an output device 3 and is connected to the database 4. The input device 2 can be implemented by a keyboard, a mouse or the like, and the output device 3 can be implemented by a display, a printer or the like.

  The database 4 is a data storage system in which various types of data called items registered by authorized users, such as binary data such as documents, images, moving images, and voices, blogs, URLs, and the like are stored.

  Each configuration of the data search device 1 will be described.

  The tag item storage unit 11 stores tag data and tag item data.

  The tag data is data indicating information about tags added to items stored in the database 4. Tag data is newly generated when a new word or phrase is registered as a tag.

  FIG. 2 is a diagram illustrating a data configuration example of tag data.

  The tag data includes items such as tag ID, tag word, number of registrations, number of browsing, creation date / time, update date / time, and deletion date / time.

  “Tag ID” is information for uniquely identifying a tag stored in the tag item storage unit 11. The “tag word” is an arbitrary character string such as a word or a phrase that is a tag added to an item in the database 4.

  “Number of registrations” is the total number of tag items for which the same tag ID is set. The tag item will be described later.

  “Number of browsing” is the total number of times the tag corresponding to the tag ID is output to the output device 3.

  “Created date / time” is the date / time when the tag data was generated, “Updated date / time” is the date / time when the content of the tag data was updated, and “Deleted date / time” is the date / time when the tag data was deleted.

  Furthermore, as shown in FIG. 2, the tag data includes the number of registrations (within 3 months), the number of registrations (within 6 months), the number of registrations (within 1 year), the number of browsing (within 3 months), the number of browsing (within 6 months). Or the number of browsing (within one year). “Number of registrations (within 3 months)” indicates the total number of registered tag items within the past 3 months from the present. Also, “Number of registrations (within 6 months)” and “Number of registrations (within 1 year)” The totals within the past 6 months and within the past year are shown. The same applies to “the number of browsing (within 3 months)”, “the number of browsing (within 6 months)”, and “the number of browsing (within 1 year)”. The number of registrations and the number of inspections divided by a period are for obtaining information indicating transitions over time.

  The tag item is data indicating a correspondence relationship between an item designated by the user and a tag added to the item. A tag item is uniquely specified by a set of a tag ID and a user ID.

  FIG. 3 is a diagram illustrating a data configuration example of a tag item.

  The tag item stored in the tag item storage unit 11 includes items such as tag ID, user input word, user ID, item ID, item type, creation date / time, update date / time, and deletion date / time.

  “Tag ID” is identification information indicating a tag word regarded as the same as a tag (user input word) input by the user, and a tag ID of tag data is adopted.

  “User ID” is information for uniquely identifying a user who added a tag to an item.

  “Item ID” is information for uniquely identifying an item to which a tag is added, and “Item Type” is information indicating the data type of the item. For each item to which a tag is added, a pair of item ID and item type is registered.

  The “user input word” is a word or phrase (character string) actually input by the user as a tag.

  “Created date / time” is the date / time when the tag item was generated, “Updated date / time” is the date / time when the content of the tag item was updated, and “Deleted date / time” is the date / time when the tag item was deleted.

  Tag data is generated by the tag editing unit 18 when a new word is input as a tag. The tag data is updated each time an item having the tag is browsed each time the same phrase as the tag word is added to or deleted from the item.

  The tag item is generated by the tag editing unit 18. Updated every time the same user adds or deletes the same tag to another item.

  FIG. 4 is a diagram illustrating the relationship between tag items and tag data.

  Assume that users A and B who use the database 4 are registered and the user A adds a tag xxx to the item d0010 (document).

  If the tag xxx is a new word and there is no tag data with the word = xxx in the tag item storage unit 11, the following tag data and tag item are generated.

New tag data = “tag ID = 001, word = xxx, number of registrations = 1,...”
New tag item = “tag ID = 001, user input word = xxx, user ID = A, item ID = d0010, item type = document,...”
Thereafter, it is assumed that the user B adds the tag yyy to the item d0015 (image). If the tag yyy is a new word, the following tag data and tag items are generated similarly.

New tag data = “tag ID = 002, word = yyy, number of registrations = 1,...
New tag item = “tag ID = 002, user input word = yyy, user ID = B, item ID = d0015, item type = image,...”
Further thereafter, assume that user A adds a tag xxx to item d0020 (URL). Here, tag data with word = xxx has already been generated in the tag item storage unit 11. Therefore, the tag editing unit 18 updates the tag data as follows to generate a tag item.

Updated tag data = “tag ID = 001, word = xxx, number of registrations = 2,...”
Updated tag item = “tag ID = 001, user input word = xxx, user ID = A, item ID = d0010, item type = document, item ID = d0020, item type = URL,...
Further thereafter, it is assumed that the user B adds a tag xxx to the item d0020 (URL). Here, tag data with word = xxx has already been generated in the tag item storage unit 11. Therefore, the tag editing unit 18 updates the tag data as follows to generate a tag item.

Updated tag data = “tag ID = 001, word = xxx, number of registrations = 3,...”
New tag item = “tag ID = 001, user input word = xxx, user ID = B, item ID = d0020, item type = URL,...
As described above, the tag data is generated only when a new word / phrase is registered, and the tag item is generated every time a new tag is added to the item for each user.

  The tag matrix editing unit 12 acquires two or more tag groups including one or a plurality of tags, which are arbitrary character strings, input by the user, and selects tags included in one of the acquired tag groups as row elements and A tag matrix having a tag included in the other as a column element is generated and stored in the tag matrix storage unit 13.

  FIG. 5 is a diagram illustrating a data configuration example of a tag matrix.

  The tag matrix stored in the tag matrix storage unit 13 has items such as matrix ID, column tag, row tag, number of items, creation date / time, update date / time, and deletion date / time.

  “Matrix ID” is information for uniquely identifying a tag matrix stored in the tag matrix storage unit 13.

  The “column tag” is information indicating a tag included in one tag group input by the user, and is specified by a tag ID. Each tag of the column tag becomes a tag item constituting the X axis when the tag matrix is displayed.

  “Row tag” is information indicating a tag included in another tag group input by the user, and is specified by a tag ID. Each tag of the row tag becomes a tag item constituting the Y axis when the tag matrix is displayed.

  “Number of items” indicates the total number of items searched by a search condition which is a combination of column tags and row tags constituting the tag matrix.

  “Created date / time” is the date / time when the tag matrix was generated, “Updated date / time” is the date / time when the contents of the tag matrix were updated, and “Deleted date / time” was the date / time when the tag matrix was deleted.

  When the tag matrix editing unit 12 receives a request to generate a tag matrix from the user, the tag matrix editing unit 12 displays a tag matrix creation screen on the output device 3 and waits for user input.

  6 and 7 are diagrams showing examples of a tag matrix creation screen.

  The tag matrix creation screen 400 shown in FIG. 6 has input areas for title, row tag, column tag, and description. “Title” is an area in which the title of the tag matrix is input. "Row tag" is an area where a word / phrase indicating a tag as a row tag is input, "Column tag" is an area where a word / phrase indicating a tag as a column tag is input, and "Description" is a tag This is an area where information about the matrix is input.

  A tag matrix creation screen 410 shown in FIG. 7 is a screen for inputting tag matrix related information. The tag matrix creation screen 410 has input or display areas such as a title, creation date, expiration date, operation at the time of expiration, permission of a comment, use of a tag matrix, and the like.

  “Title” is an area in which a title input on the tag matrix creation screen 400 is displayed, and “creation date” is an area in which date information for creating the tag matrix is input.

  The “expiration date” is an area in which date information indicating a time limit when the browsing of the tag matrix is set as a fixed term is input.

  “Expiration when expired” includes an area for inputting a process to be executed when the expiration date specified for the expiration date is reached, “Allow comment”, an area for specifying whether other users' comments are permitted for the tag matrix, and “Tag The “use of matrix” is an area for designating preferential display of the tag matrix.

  Each area of the tag matrix creation screen 410 is additional. Further, the input of “operation upon expiration, permission of comment, use of tag matrix” may be specified by selecting a menu prepared in advance.

  For each tag matrix stored in the tag matrix storage unit 13, the item count totaling unit 14 uses a combination of row tags and column tags corresponding to each cell (intersection) of the tag matrix as a search condition, and the tag item storage unit 11 The tag item stored in is searched, the number of items to which a tag that matches the tag combination is calculated, and written to the cell total data corresponding to each cell.

  FIG. 8 is a diagram illustrating a data configuration example of the cell total data.

  Cell aggregation data is generated for the cells of the tag matrix. It has items of a first tag, a second tag, and the number of items. The “first tag” is a tag ID constituting a column tag of the tag matrix, the “second tag” is a tag ID constituting a row tag of the tag matrix, and the “number of items” is a column tag tag ID and a row tag tag Indicates the number of item IDs searched for in pairs with IDs.

  When the tag matrix output unit 15 receives a tag matrix display request from the user via the input device 2, the tag matrix output unit 15 extracts the tag matrix requested to be displayed from the tag matrix storage unit 13 and outputs the corresponding tag matrix to the output device 3. Output to.

  9 to 11 are diagrams showing display examples of the tag matrix.

  A tag matrix display screen 420 shown in FIG. 9 is a screen for displaying a tag matrix stored in the tag matrix storage unit 13, and displays areas of “a frequently browsed tag matrix” and “a recently browsed tag matrix”. Have.

  “Frequently viewed tag matrix” is an area in which the title or thumbnail of a tag matrix having a large number of browsing is displayed, and “Recently viewed tag matrix” is a title of a tag matrix having a large number of browsing in the most recent period. Or an area where thumbnails are displayed. The number of browsing of the tag matrix is obtained from a browsing log described later.

  A tag matrix display screen 430 shown in FIG. 10 is a screen for displaying the tag matrix selected in FIG.

  Tag matrix display screen when “Portal site, virtualization, server,…” is set in “Column tag” of tag matrix, and “Portal site, sales promotion, proposal,…” is set in “Row tag” Tags (words / phrases) registered in the column tag and row tag items are displayed in the tag matrix 430. In the cell that is the intersection of each item of the tag matrix, the number of items retrieved by the combination of the corresponding column tag and row tag is displayed.

  For example, the access number “50” displayed in the cell at the intersection of column tag = portal site and row tag = portal site is the number of items to which the tag “portal site” is added among the items stored in the database 4. Represents 50. Similarly, the access number “10” of the cell at the intersection of column tag = portal site and row tag = expansion sales indicates that the number of items to which the tags “portal site” and “sales expansion” are added is 10.

  Further, the tag matrix output unit 15 is extracted from the tag item storage unit 11 by the combination of the column tag and the row tag corresponding to the cell (intersection) selected on the tag matrix displayed on the tag matrix display screen 430. All the tags attached to each item from all the existing items, identify the tags other than the tags set in the tag matrix column tag and row tag among the acquired tags as the classification tags, and identify the specified classification tags Output a list of.

  Further, the tag matrix output unit 15 displays a list of items extracted by a search process using a combination of column tags and row tags corresponding to cells (intersection points) selected on the tag matrix displayed on the tag matrix display screen 430. Is output.

  The tag matrix display screen 440 shown in FIG. 11 shows the items displayed as the number of items = 10 in the cell when the intersection of “portal site” and “expansion” in the tag matrix shown in FIG. 10 is selected. This is a screen for displaying a list.

  The tag matrix display screen 440 has a display area for a combination of selected tags, a list of items, and a list of other tags.

  “Selected tag combination” is an area in which column tags and row tags corresponding to cells (intersection points) selected on the tag matrix displayed on the tag matrix display screen 430 are displayed.

  The “item list” is an area in which items specified as the number of cells written in a selected cell, that is, items to which corresponding column tags and row tags are added are displayed as a list. In the example shown in FIG. 11, the item title and the creation date / update date / time are stored in the database 4 as information specifying each item to which the two tags “portal site” and “sales expansion” are added. It is displayed.

  In the “item list”, descriptions of items stored in the database 4 as item related information may be displayed together with the titles of each item and the generation date / update date.

  The “other tag list” is a tag other than the column tag and the row tag of the tag matrix among all the tags added to the cell (intersection) selected in the tag matrix displayed on the tag matrix display screen 430. This is an area where a list of classification tags is displayed. The classification tag is the third and subsequent tags other than the column tag and the row tag added to the item.

  When a tag is selected in the “other tag list” on the tag matrix display screen 440, the tag matrix output unit 15 selects the item displayed on the “item list” on the tag matrix display screen 440. Refine search by tag. Then, the item to which the selected tag is added is extracted, and a list of the items is displayed in the tag matrix display screen 440. Further, when another tag is selected in the “other tag list” on the tag matrix display screen 440, the tag matrix output unit 15 performs the same narrowing process on the selected tag.

  Further, the tag matrix output unit 15 accumulates display processing log information in the display log storage unit 17 each time the tag matrix is displayed. Furthermore, the number of browsing for a predetermined period is totaled and the number of browsing of the corresponding tag data is updated.

  FIG. 12 is a diagram illustrating a data configuration example of the browsing log accumulated in the display log storage unit 17.

  The browsing log has items such as tag ID, user ID, creation date and time. "Tag ID" is the tag ID of the tag added to the viewed item, "User ID" is the user ID of the user who viewed the item, and "Creation date" is information indicating the date and time when the browsing log was generated .

  The display log storage unit 17 performs a known log information accumulation process, and a detailed description thereof will be omitted.

  When an item of “item list” on the tag matrix display screen 440 is selected, the item output unit 16 takes out the corresponding item from the database 4 using the item ID and displays it on the output device 3.

  The tag editing unit 18 adds, updates, and deletes tags added to the items in the database 4.

  When the user requests input of a tag, the tag editing unit 18 displays a tag input screen and adds the input tag to the specified item.

  FIG. 13 is a diagram illustrating a display example of the tag input screen 450.

  The tag input screen 450 includes an item title, a registered tag, a tag input area, a registration button area, a clear button area, and the like.

  The “item title” is an area for displaying an item (item title) to which a tag is added, and the “registered tag” is an area for displaying a tag (user input word) input by the user. “Tag input” is an area in which a word / phrase (character string) added as a tag is input. The “registration button” is a button for requesting tag input by a word / phrase input for tag input, and the “clear button” is a button for canceling the tag input request.

  When the user inputs a word or phrase to the tag input on the tag input screen 450, the tag editing unit 18 displays the tag input word and phrase (user input word), the item ID and item type of the item displayed in the item title. And a user ID are acquired. If the tag item having the same user ID and user input word is not stored in the tag item storage unit 11, the tag editing unit 18 generates a tag item having the data configuration shown in FIG. If tag items having the same user ID and user input word are already stored in the tag item storage unit 11, the tag editing unit 18 adds the item ID and item type to the tag item having the same user input word. Then, the update date is rewritten to the current date.

  Further, the tag editing unit 18 takes out tag data (see FIG. 3) having the same tag ID from the tag item storage unit 11, adds 1 to the registered number, and rewrites the update date and time to the current date and time.

  When the user requests to delete the tag added to the item, the tag editing unit 18 is a screen similar to the tag input screen 450 and displays the tag added to the specified item. Display a screen (not shown), delete the item ID and item type of the specified item from the tag item corresponding to the tag to be deleted (user input word) specified in this screen, and set the update date and time. rewrite.

  Further, the tag editing unit 18 detects the fluctuation of the user input word input by each user and stored in the tag item for each predetermined trigger or period, and a plurality of notations are mixed in the tags representing the same meaning. Find out what you are doing. Then, the largest number of notations are selected, and tags based on the selected notation are set in the tag words of the corresponding tag data. The notation fluctuation is presence / absence of a long sound symbol, a kana character, uppercase / lowercase letters, full / half-width differences, etc., for example, “server, server”, “window, window”, “Internet, internet, Internet, internet”, etc. is there.

  Note that the tag editing unit 18 performs known notation fluctuation detection processing, and thus detailed description thereof is omitted.

  Thereby, the tag matrix output unit 15 can display the display of the tag matrix and the classification tag by adopting the maximum number of notations.

  Hereinafter, the processing flow of the data search device 1 will be described with reference to FIGS.

  FIG. 14 is a diagram illustrating a processing flow example of the tag editing process.

  The tag editing unit 18 of the data search apparatus 1 receives a tag editing request from the user, specifies an item for editing the tag (step S1), and specifies the editing operation content (step S2).

  If the editing operation content is “add” (“add” in step S2), the tag editing unit 18 accepts the tag to be added (step S3), and whether there is tag data having the same tag word as the accepted tag. (Step S4).

  If there is corresponding tag data (Y in step S4), the tag editing unit 18 updates the registered number of the corresponding tag data (step S5), and if there is no corresponding tag data (N in step S), the tag Data is generated and stored in the tag item storage unit 11 (step S6).

  Further, the tag editing unit 18 searches for a tag item using the tag ID and user ID of the corresponding tag data, and if there is a corresponding tag item (Y in step S7), the item ID, item type is included in the corresponding tag item. Is updated by adding (step S8). If there is no corresponding tag item (N in step S7), a tag item storing the tag ID, the user ID, the tag (user input word), the item ID of the specified item, and the item type is generated and the tag item storage unit 11 (step S9).

  If the editing operation content is “deletion” in the process of step S2 (“deletion” in step S2), the tag editing unit 18 accepts the tag to be deleted input by the input device 2 (step S10), The specified item ID and item type are deleted from the tag item of the corresponding tag stored in the tag item storage unit 11. If only the specified item is added to the tag item of the tag to be deleted, the tag item itself may be deleted (step S11). Then, the number of registered tag data of the tag to be deleted is updated (step S12).

  If the editing operation content is “edit related information” in the process of step S2 (“edit related information” in step S2), the tag editing unit 18 identifies a tag item corresponding to the user ID and item ID. Then, the information to be edited is received via the input device 2 (step S14), and the tag item is updated (step S15).

  FIG. 15 is a diagram illustrating a processing flow example of the tag matrix editing process.

  When the tag matrix editing unit 12 receives a tag matrix editing request from the user, the tag matrix editing unit 12 specifies the editing operation content (step S20).

  If the editing operation content is “Generate” (“Generate” in Step S20), the tag matrix editing unit 12 accepts input of tags for each of the column tag and the row tag (Step S21), and selects the column item. For each tag in the column tag group, a tag matrix is generated in which the row item is composed of each tag in the row tag group (step S22), and related information of the tag matrix is generated from the other input information (step S23). ), The tag matrix is stored in the tag matrix storage unit 13 (step S24).

  If the editing operation content is “deletion” in the processing of step S20 (“deletion” in step S20), the tag matrix editing unit 12 specifies and extracts the tag matrix to be deleted from the tag matrix storage unit 13 (step S20). S25), the tag matrix is deleted (step S26).

  If the editing operation content is “editing” in the process of step S20 (“editing” in step S20), the tag matrix editing unit 12 specifies the corresponding tag matrix and related information from the tag matrix storage unit 13. Extraction (step S27), information to be edited is received (step S28), and the tag matrix or related information is updated with the received information (step S29).

  FIG. 16 is a diagram illustrating a processing flow example of the tag matrix item count processing.

  The item count totaling unit 14 extracts tag matrices one by one from the tag matrix storage unit 13 and performs the following processing.

  The item count totaling unit 14 specifies a tag matrix to be extracted (step S30), and generates a pair of a corresponding column tag and row tag for each cell of the tag matrix. Then, the database 4 is searched using the generated pair as a search key, and the corresponding item is extracted (step S32). The number of items included in the search result is totaled and written to the cell total data of the corresponding cell (step S33).

  If all the cells have been searched (Y in step S34), the process ends. If not (N in step S34), the process returns to the process in step S32, and the processes in steps S32 to S33 for the next cell. I do.

  FIG. 17 is a diagram illustrating a processing flow example of the tag matrix display processing.

  The tag matrix output unit 15 takes out the selected tag matrix from the tag matrix storage unit 13 and displays it on the output device 3 (step S40).

  Next, when a cell is selected in the displayed tag matrix, the tag matrix output unit 15 specifies a column tag and a row tag corresponding to the selected cell (step S41), and searches by the specified tag pair. An item is acquired (step S42). Further, all the tags of the retrieved item group are acquired as classification tags, and the number of items is totaled for each classification tag (step S43).

  The tag matrix output unit 15 displays a list of the searched item groups in a predetermined order (for example, in descending order of the number of browsing, newest update date, etc.), and lists the classification tags in order of the number of items (step S44). ).

  Thereafter, the tag matrix output unit 15 detects whether or not the user has selected from the displayed tag matrix, item list, and classification tag list (step S45), and if the selected target is a “classification tag”. If the tag is selected ("tag" in step S45), the item displayed in the list is searched with the selected classification tag, the item to which the selected classification tag is added is extracted, and the narrowed item is displayed (step). S46).

  If the selected target is “item” (“item” in step S45), the item output unit 16 extracts the content of the selected item from the database 4 and displays it on the output device 3 (step S47). .

  The data retrieval apparatus 1 shown in FIG. 1 can be implemented by computer hardware and a computer-executable program. In this case, a program describing the processing contents of functions that the data retrieval apparatus 1 should have is provided. Provided. When the provided program is executed by the computer, the processing function of the data search device 1 described above is realized on the computer.

  The above-mentioned computer can also read a program directly from a portable recording medium and execute processing according to the program. Alternatively, each time the program is transferred from the server computer, the computer sequentially follows the received program. Can also be executed. Furthermore, this program can be recorded on a computer-readable recording medium.

  In the above description, the case where the present invention is applied to the data search processing of the data sharing system, which is the technical field behind the above, has been described. However, the present invention is not limited to this, and is within the scope of the description. Naturally, various modifications are possible.

  Further, the tag matrix processed by the data search device 1 can be handled as items stored in the database 4. In this case, the database 4 stores the tag matrix storage unit 13 configured inside the data search device 1. I can also serve.

  Further, another tag matrix can be included in the item list searched and displayed by the tag matrix.

  Moreover, you may include the item which shows the tag which set the relationship of the parent or the child in tag data. Thereby, tags can be hierarchized.

  As described above, the present invention has the following effects.

  According to the present invention, a user can classify data stored in a database by setting an arbitrary character string and an arbitrary number of tags.

  Furthermore, the user can set the conditions for searching the data in the database with two or more tag groups that include an arbitrary number of arbitrary tags.

  The user can change and save the search conditions used in the search operation when the search conditions are partially changed to obtain a related search result or a search result to be compared. The user can easily repeat the search process using the same search condition simply by specifying the matrix, and can easily obtain the search result.

  In addition, since the user can simultaneously obtain the number of searched items as a search result corresponding to each cell of the tag matrix, it is possible to see at a glance what classification data is stored in the database. Can be grasped.

  For example, as two tag groups, a tag matrix of a tag group indicating a customer's business type (tags for medical, finance, manufacturing, etc.) and a tag group indicating a business phase (tags for sales, design, operation, etc.) are set. In this case, the user can easily determine the situation (information uneven distribution) as to whether the information is enriched or short in which business field for which customer field, depending on the number of matrices retrieved by the combination of each tag group. I can know. Furthermore, users can be encouraged to actively register data on fields with a small number of items, and the database can be enhanced.
