Abstract

When registering a document of a page by dividing an original document, a headline included in the table of contents information is automatically used as a tag, so that a standard tag can be provided in a wide range without a drill-down search. The task is to increase efficiency. Using table of contents information included in an electronic document such as PDF, a tag of a heading related to a section such as a chapter or a section is used as a menu item of a menu used for a drill-down search of a page document divided into pages. . The chapter number uses the heading code tag as the menu item, and the chapter title uses the heading title tag as the menu item. In the search result list, the notation page in the original document is displayed together with the title of the page document. [Selection] Figure 28

Description

  The present invention relates to a technique for dividing an original document shared by a plurality of users into page documents, and performing tagging for use in a drill-down search of page documents based on table of contents information.

  Patent Document 1 discloses a content recommendation device and method using a tag cloud.

  In this example, a content recommendation server that provides a content recommendation service through a network constructs a tag cloud by analyzing a tag attached to each content. The tag used here is premised on the user directly assigning the content.

  As described above, it is common for a user to consciously set a tag used for content search or the like.

  However, users often find it cumbersome to determine and set tags themselves, and it is not always easy to tag documents shared by many users. is not.

  In addition, since judgments on the suitability of tags are different for each user, it is difficult to unify them into standard tags, and it is difficult to achieve stable operation in a structured search.

  FIG. 1 is a diagram showing a network configuration (part 1) according to the present invention. An example (Saas form) in which a document sharing system is provided outside a company (an example of an organization that shares documents) is shown. The document sharing system according to the present invention includes a document management server 101, a search server 102, and a shared file server 103. The document management server 101 creates and browses documents, registers an index table in the search server 102, and the like. The search server 102 performs a high-speed search using the index table and plays a role of guiding a user to desired document information. The shared file server 103 is a server that stores a shared document file. The document management server 101, the search server 102, and the shared file server 103 are connected by a system network (for example, LAN) in the document sharing system. The document management server 101, the search server 102, and the shared file server 103 are connected to the Internet via a system network. The user terminal 104 is a terminal used by a user who registers and browses a shared document, and is connected to an internetwork via a corporate network (for example, a LAN). Accordingly, the user terminal 104 is configured to be able to access the document management server 101, the search server 102, and the shared file server 103. The user terminal 104 has a browser, and can communicate with the document management server 101, the search server 102, and the shared file server 103 via the browser. From the viewpoint of security, it is desirable that communication data via the Internet is encrypted on the transmission side and decrypted on the reception side. The user terminal 104 may be used as a user who registers a document or may be used as a user who browses a document.

  Besides the form of Saas, a document sharing system can also be provided in the company. FIG. 2 is a diagram showing a network configuration (part 2) according to the present invention. The document management server 101, search server 102, shared file server 103, and user terminal 104 are connected to a corporate network (for example, a LAN). In this example, on the premise of an intranet, the user terminal 104 can communicate with the document management server 101, the search server 102, and the shared file server 103 via a browser as in the Saas form. Cooperation among the document management server 101, the search server 102, and the shared file server 103 is also performed through the corporate network.

  In any network configuration, when the document management server 101 or the search server 102 stores a shared file, the shared file server 103 can be omitted.

  First, an operation for registering a page document from the user terminal 104 to the document management server 101 will be described. The original document file to be divided is transferred, and the document management server 101 registers, as shared information, a page document obtained by dividing the original document into pages based on the table of contents information included in the original document file. The original document file is an electronic document including table of contents information. For example, a PDF: Portable Document Format document file is used.

  FIG. 3 is a diagram showing a data flow related to document registration. When the document management server 101 receives a document creation start from the user terminal 104, it returns a document type selection screen. The document type selection screen is configured to select a document type such as a manual page or a test specification page. The manual page is a document composed of manual pages, and the test specification page is a document composed of test specification pages. A document type designation (including a document type ID) is transmitted from the user terminal 104, and the document management server 101 returns a page document input form screen corresponding to the document type. The page document input form screen is configured to prompt input of entry data for each item, further prompt input of the original document file, and reply. At that time, the document type ID is also returned.

  FIG. 4 is a diagram illustrating a configuration of a document management server according to document registration start. The document management server 101 includes a document type selection screen distribution unit 401, a document type selection screen storage unit 402, a page document input form screen distribution unit 403, a page document input form screen storage unit 404, and a tag table 405. Subsequently, processing by these modules will be described.

  FIG. 5 is a diagram showing a document type selection screen distribution processing flow. When the document type selection screen distribution unit 401 waits for reception of the document creation start (S501) and receives the document creation start from the user terminal 104, the document type selection screen storage unit 402 stores the document type selection screen stored in the document type selection screen storage unit 402. Is returned to the transmitting user terminal 104 (S502). The document type selection screen is configured to display a list of document types, prompt selection of the document type, and return a document type specification including the ID of the selected document type to the document management server 101 by clicking or the like. . Upon receiving this screen, the user terminal 104 displays this screen on the browser and accepts selection of the document type created by the user. For example, the document creation start and the document type designation are respectively predetermined URLs, and the document type ID is added to the URL as a parameter.

  FIG. 6 is a diagram showing page document input form screen distribution processing. When the page document input form screen distribution unit 403 waits for the reception of the document type designation (S601) and receives the document type designation from the user terminal 104, the page document input form screen distribution unit 403 inputs the page document corresponding to the document type ID included in the document type designation. The form screen is read from the page document input form screen storage unit 404 and sent back to the user terminal 104 that has sent the form screen (S602). The page document input form screen is provided with a character code input field for an item to be entered or tag selection means in accordance with the document data structure for each document type. In addition, a file designating unit for designating a file that can be read by the user terminal 104 as an original document is provided. A file designated by the file designation means is read as an original document file and transferred to the document management server 101.

  FIG. 7 is a diagram showing a page document input form screen for manual pages. In the example of the manual page, in addition to the creator, entry items such as a document title, a theme, an original document file, and a notation page start position are provided. The creator specifies from the user ID at the time of login and is set in advance, but the user may input a code or select a tag. A character code can be freely input for the document title. The theme is configured to select a preset tag name. Tag names are displayed in a pull-down list. When a tag is selected, a tag ID is returned. When the document management server 101 specifies the tag ID from the tag name, the tag name may be returned. The original document file is designated from a directory in a drive in the user terminal 104 or a directory in a server connected to the corporate network.

  The notation page start position is a constituent page where the notation page starts. The written page is a page written in the document, that is, a page for user recognition guided in the table of contents. The component page is a page managed as an electronic document, that is, an actual page that can be displayed or printed. The notation page start position means the number of constituent pages corresponding to the first page of the notation page. For example, if the cover page is 1, the foreword is 1 page, the table of contents is 1 page, and the text is 10 pages, the total number of pages is 10 and the number of constituent pages is 13 pages. The notation page start position is page 4. 1 is added to the number of pages before the text. Regardless of this example, the number of pages before the text may be input, and 1 may be added to obtain the notation page start position. If there is no previous page of the text and the notation page matches the constituent page, it may be omitted. Also, the case where the correspondence between the notation page and the constituent page can be calculated from the management information of the original document can be omitted.

  These entry data are transmitted by instructing by clicking the transmission icon. At the same time, the designated original document file and document type ID are also transmitted. When the document type ID can be specified on the document management server 101 side, the document type ID can be omitted.

  Management of document types is facilitated by providing a document type management table. FIG. 8 is a diagram showing a document type management table. For each document type, a record that associates the document type ID 801, the document type name 802, and the fields of the page document input form screen 803 is provided.

  The creator is registered in advance as a person name tag. The theme is also preset as a theme tag. FIG. 9 is a diagram showing a tag table. For each tag, a record for associating the fields of tag ID 901, tag type 902, and tag name 903 is provided. A tag ID 901 is unique for a combination of a tag type 902 and a tag name 903. The page document input form in the page document input form screen storage unit 404 is set to match the information in the tag table 405. Alternatively, the page document input form screen distribution unit 403 is set to match. A header code and a header title, which will be described later, are also registered as a header code tag and a header title tag.

  FIG. 10 is a diagram showing the configuration of the document management server related to the page document registration process. In addition to the tag table 405, the document management server 101 includes an entry data reception unit 1001, an original document reception unit 1002, an original document storage unit 1003, a table of contents acquisition unit 1005, a table of contents storage unit 1006, a page document generation unit 1007, and a page document storage unit. 1008, a document data structure storage unit 1009, and a document management server 1010. Although the original document storage unit 1004 is assumed to be provided in the shared file server 103, it can also be provided in the document management server 101.

  Next, the document registration process will be described. FIG. 11 is a diagram showing a page document registration process flow. The entry data receiving unit 1001 receives entry data and a document type ID from the user terminal 104 while waiting for reception of entry data and a document type ID (S1101).

  Subsequently, in the original document receiving process of the original document receiving unit 1002 (S1102), the original document file is received. In the original document storage process (S1103), the original document storage unit 1003 stores the received original document file in a predetermined position (server, drive, directory) of the original document storage unit 1004 with a predetermined file name. FIG. 12 shows the original document storage processing flow. The original document location in the original document storage unit 1004 is determined (S1201), and the original document file is stored in the original document location (S1202). Normally, the original document file name is changed to a management file name, but the original document file name may be used as long as there is no duplication.

  The table of contents acquisition unit 1005 acquires table of contents information from the original document file in the table of contents acquisition process (S1104). FIG. 13 is a diagram showing a table of contents acquisition processing flow. The original document file is read from the original document location (S1301), and the table of contents information is specified from the original document file (S1302). The table of contents information may be a part of the document information (for example, a predetermined configuration page), or a system that is held as management information. The procedure for acquiring the table of contents information depends on the storage method of the configuration of the electronic file and the document editing rules. Then, for each heading, the heading number, the heading title, and the description page range are associated with each other and stored in the table of contents storage unit 1006 (S1303).

  FIG. 14 is a diagram showing an example of the table of contents information (XP service manual) of the original document. The heading number is a character code for identifying the constituent part (document classification) by the user, and is generally expressed by a chapter, a section, an item, an eye, or the like. The headline title is a character code indicating the content and purpose of the component. The range of the description page is a start page and an end page of the range included in the constituent parts.

  In the page document generation process (S1105), the page document generation unit 1007 divides the original document to generate a page document file and registers management document information. The page document file is not information for the user to browse but information for generating an index by the search server 102. The user is configured to browse each page of the original document file in the original document storage unit 1004.

  FIG. 15 is a diagram showing a page document generation processing flow. A description page is specified from the table of contents information, and the following processing is repeated for each description page (S1501). A new registered document ID is assigned and set in the document information (S1502). Subsequently, a common item setting process (S1503) and a page-specific item setting process (S1504) are performed, and the process ends when all the description pages are processed (S1505).

  Common items and page-specific items are defined in the document data structure. FIG. 16 is a diagram illustrating a document data structure of a manual page. The document type ID has information on a plurality of document items. Each item associates a document item ID, a document item name, a document item type, and a text text flag. The document item ID is unique for the item in the document, and the document item name is used for identifying the contents of the item and displaying the screen. The document item type defines a data format. The name tag and the theme tag are tags and define the tag type. The body text flag is set so that an item to be body text displayed in the search result list is distinguished as ON. The document item information is divided into items common to each page and items different for each page.

  An example of generated document information is shown. FIG. 17 is a diagram illustrating an example (first page) of document information of a manual page. FIG. 18 is a diagram illustrating an example (third page) of document information of a manual page. These are page documents generated from a common original document file. In the header, in addition to the registered document ID and the document type ID, a creation date and an update date are stored as properties. In addition, document item data is stored for each document item ID. In the tag item, the received tag ID is stored. When a tag name is received as entry data, the document generation unit 1007 specifies a tag ID corresponding to the tag name based on the tag table 405. The character string stores the received character code. The original document file storage location (original document storage unit 1004) is stored in the original document location, and the page document location storage location (page document storage unit 1008) is stored in the page document location.

  The common item setting process (S1503) will be described in detail. FIG. 19 is a diagram showing a common item setting process flow. The document type ID is specified and set in the document information (S1901), the property is acquired and set in the document information (S1902). The entry data corresponding to the creator's item is specified (S1903). Then, the entry data is written in this creator item of the document information (S1904). At this time, the entry data is a tag ID of a person name. Next, entry data corresponding to the document title item is specified (S1905). The entry data is written in the document title item of the document information (S1906). The entry data is a character code. The original document location is acquired from the original document storage unit 1003 (S1907), and the original document location is written in the item of the document information (S1908). Entry data corresponding to other items included in the document data structure corresponding to the document type ID is specified (S1909). It is an item after IT04. The entry data is written in the item of the document title of the document information (S1910).

  The page-specific item setting process (S1504) will be described in detail. FIG. 20 is a diagram showing a page-specific item setting process flow. The number of difference pages is obtained by subtracting 1 from the notation page start position. The number of difference pages corresponds to the number of pages before the text. The difference page number is added to the description page number, and the corresponding constituent page number is specified (S2001). Further, the page document location is determined (S2002). In this example, a configuration page is added to the end of the file name. The constituent pages of the original document file are copied to generate a page document file at the page document location (S2003). At this time, the previously determined file name is used. Then, the description page, configuration page, and page document location of the document information are written in each item (S2004). Furthermore, entry data corresponding to the item of the heading number included in the document data structure corresponding to the document type ID is specified (S2005). In this example, IT14. The heading number of the page is obtained from the table of contents information and written in the heading number item of the document information (S2006). At this time, the tag name that matches the heading number is searched from the tag table 405, the corresponding tag ID is specified, and the tag ID is written. Further, entry data corresponding to the heading title item included in the document data structure corresponding to the document type ID is specified (S2007). In this example, IT15. The entry data is written in the heading title item of the document information (S2008). At this time, the tag name that matches the heading title is searched from the tag table 405, the corresponding tag ID is specified, and the tag ID is written.

  In this way, document registration is completed. Next, an index registration operation for making a document registered in this way a search target will be described.

  FIG. 21 is a diagram showing a configuration of a document management server related to index registration. In addition to the tag table 405, the document data structure storage unit 1009, and the document management server 1010, the document management server 101 includes an index table generation unit 2101, a menu tag correspondence table 2102, an index table storage unit 2103, and an index generation command activation. Part 2104. The index table generation unit 2101 generates an index table for the registered document. The index table generation unit 2101 may be configured to be activated in conjunction with document registration, or may be configured to process a group of documents by batch processing.

  FIG. 22 shows an index table. For each index target document, the document title 2201, creator 2202, creation date 203, body text source 2204, first menu item (field) 2206, second menu item (section number) 2207, third menu item (section title) 2208, a fourth menu item (personnel) 2209, a location 2210, a configuration page 2211, and a description page 2212 are associated with the record. The document title 1701 and the body text 1704 are displayed as a search result list and a search area for keyword search. The menu item is a selection candidate belonging to the menu (field, section number, section title, personnel, etc.). Here, the character code string is set. The location indicates location information accessed during document display. The configuration page is specified after the file name. That is, the position of the constituent page in the original document is designated. As a result, the page is directly displayed on the browser. Although omitted in this example, it is also effective to include the update date and time.

  An index registration operation on the document management server 101 side by the index table generation unit 2101 and the index generation command activation unit 2104 will be described. FIG. 23 is a diagram showing an index registration processing flow. The index table generation unit 2101 identifies unregistered document information from the document management server 1010, and repeats the following processing for each unregistered document information (S1801). Unregistered methods include a method of determining a document having a creation date or an update date since the previous index registration process, or a method of determining by turning on a creation / update flag at the time of creation / update. Not only unregistered documents but all documents may be targeted.

  The index table generation unit 2101 performs processing for generating additional records in the index table storage unit 2103 (S2302) for all document information (S2303). Then, the index generation command starting unit 2104 transfers the index table in the index table storage unit 2103 to the search server 102 together with the index generation command by the index generation command starting process (S2304).

  FIG. 24 is a diagram showing a record generation processing flow. The document title is read from the document information of the document management server 1010, the creator is read, the creation date and time are read, and written into the index records (S2401 to S2403). For the creator, the tag ID of the document item data is converted into a tag name using the tag table 405. Also, the item of the body text flag ON of the document information is specified (S2404), and the data of the item is written in the body text (S2405). Further, for each menu (S2406), the tag type corresponding to the menu is specified (S2407), the document item whose document item type is the tag type is specified (S2408), and the data of the document item is stored in the menu. The item is written (S2409).

  The tag type is specified using the menu tag correspondence table 2102 (S2407). FIG. 25 is a diagram showing a menu tag correspondence table. A tag type 2501 and a drill-down item ID 2502 are associated with each drill-down item.

  The document item is specified based on the document data structure storage unit 1009 (FIG. 14) (S2408). For example, in the document data structure corresponding to the document type ID, the item whose document item type is a theme tag, the item whose document item type is a header code tag, the item whose document item type is a header title tag, and the document item type is The item which is a person name tag is determined.

  When writing, the tag ID is converted into a tag name using the tag table 405 (S2409). When there are a plurality of tags, a delimiter code (for example, a blank code) is inserted.

  When all the menus are processed (S2410), an instruction to display the constituent page is added to the original document location, and a location is generated and written (S2411). Finally, the configuration page and the description page are written (S2412).

  Next, the operation on the search server side will be described. FIG. 26 is a diagram illustrating a configuration of a search server related to search screen distribution. The search server 102 includes an index generation unit 2601, an index database 2602, a search screen distribution unit 2603, and a search screen generation unit 2604.

  When receiving the index generation command from the document management server 101, the index generation unit 2601 reads the received index table and additionally registers it in the index database 2602. Duplicate existing documents are deleted. The index database 2602 is configured to hold index information for each document while maintaining the correspondence between the fields of the index table. At this time, the page document location set in the document text source of the index is accessed, the page document file is acquired, and the body text is extracted from the page document file. Then, the extracted body text is held as an index.

  In this state, an operation for distributing a search screen in response to a search request will be described. FIG. 27 is a diagram showing a search screen distribution processing flow. When the search screen distribution unit 2603 receives the search request (search URL indicating the search server 102) from the user terminal 104 of the user browsing the document while waiting for the search request (S2701), the search screen generation unit 2604 A search screen is generated (S2702), and the search screen is returned to the user terminal 104 that has transmitted the search request (S2703).

  FIG. 28 is a diagram showing a search screen. On the left is the drill-down search area. The upper right is the keyword search area. The lower right is the search result list display area. The drill-down search area displays, for each menu, a menu item included in the menu in a state where an instruction operation (clicking) is possible. The number of documents corresponding to the menu item is added to the menu item. In the search result list display area, the document title of the searched document is displayed in a state where it can be instructed (clicked), and the head part (predetermined number of characters range) of the body text is displayed.

  In the XP normal test collection in FIG. 28, the chapter of data registration starts from page 9. FIG. 29 is a diagram showing an example of the table of contents information (XP normal test collection) of the original document.

  In the search screen generation process by the search screen generation unit 2604, a drill-down search area and a search result list are generated for the search screen in the initial state. FIG. 29 is a diagram showing a search screen creation process flow. Drill-down search area generation processing (S2901) and search result list generation processing (S2902) are performed.

  FIG. 31 is a diagram showing a drill-down search area generation processing flow. The following processing is repeated for each menu (S3101). A menu item included in the menu is specified (S3102). The menu items of the index group in the menu tag correspondence table 2102 are read, and the menu items are sequentially specified without duplication and omission. For each menu item, the number of documents including the menu item is counted (S3103). When all the menus are processed (S3104), for each menu again (S3105), first, menu names are arranged (S3106). Subsequently, the menu items are sorted in descending order of the number of documents (S3107), and according to the order, the menu item name and the number of documents are arranged for each menu item (S3108). Further, a search request URL pointing to the search server 102 is set as a link destination to be accessed when the menu item is instructed (clicked) on the browser. A menu item (information that can identify a menu item such as a menu item name or menu item number) is added as a parameter to the search request URL (S3109). When all menus have been processed, the process ends (S3110).

  FIG. 32 is a diagram showing a search result list generation processing flow. If there is a menu item parameter in the search request URL at the time of access, the following processing is performed (S3201). If there is a keyword parameter, the keyword search is performed. If there is no parameter, the search is not performed.

  A document including menu items is searched from the index database 2602 (S3202), and the following processing is repeated for each searched document (S3203). A document title and a description page are arranged (S3204), and a location included in the index is set as a link destination to be accessed when the document title is instructed (clicked) on the browser (S3205). Further, the body text is arranged within a predetermined range (S3206). Repeat until the limit of the number of displayed documents is reached (S3207). The limit is determined by the display area and the number of displayed documents.

  When a document in the search result list is instructed on the browser of the user terminal 104, a location indicating the original document storage unit 1004 is accessed. In this example, the shared file server 103 is assumed. The shared file server 103 delivers a screen displaying the document page to the user terminal 104 in response to the document display request by this access.

  The document management server 101, the search server 102, the shared file server 103, and the user terminal 104 are computers, and each element can execute processing by a program. Further, the program can be stored in a storage medium so that the computer can read the program from the storage medium.
