JP5121194B2 - Organization information retrieval system and organization information retrieval program - Google Patents

Description

The present invention relates to an in-organization information search system and an in-organization information search program for efficiently searching for information shared in an organization such as a company.

  Traditionally, electronic documents (office formats such as plain text, HTML, Word, Excel, Powerpoint, PDF, etc.) stored in file servers and groupware within an organization such as a company, that is, contents are shared within the organization. In addition, tools for promoting creation / registration of content and for efficiently searching for content have been used.

  For example, in the in-company information registration promotion system described in Patent Document 1, statistics such as the number of accesses to contents and the number of downloads are performed and presented to employees in the organization. Motivation can be promoted. It is also possible to display the ranking of the number of accesses to the content.

  In addition, the information sharing support system described in Patent Document 2 can improve the motivation of employee content creation and registration by adding evaluation points according to the amount, quality, and utilization of content provided by employees.

  Further, in the related document search program, apparatus, and method described in Patent Document 3, a reference log for registered content is recorded, and the frequency with which the user refers to the content is indicated based on the log. A reference frequency score is calculated, and content having a high degree of matching can be displayed as a search result based on the reference frequency score when searching for content.

  However, such a content sharing search system and method have the following technical problems.

Japanese Patent Application Laid-Open No. 2002-2858808 JP 2001-222597 A JP 2005-332326 A

  The inventions described in Patent Document 1 and Patent Document 3 are characterized in that the usefulness of content is evaluated based on the number of accesses and logs. However, if the number of accesses is simply added, evaluation points are included in the evaluation. May be included in the form of access to the organization chart to increase the number of users, or may include the case where the same person simply clicked the content several times. It's hard to say. And searching and displaying content using such usefulness is also not effective for employees.

  In that respect, the invention described in Patent Document 2 gives weights when assigning points based on the amount, quality, and utilization of content provided by employees. This weighting is statically determined in advance. In the first place, if the weighting method is wrong, the point has no meaning and is unreliable.

  In addition, as a method of utilizing the content, it is conceivable to share the bookmark within the organization by using a bookmark function provided in an Internet web browser.

  However, content sharing is restricted within an organization based on the access rights of individual members. That is, since not all members can browse (display) all content, bookmarks of content that a certain member should not be able to browse or browse should not be shared.

  Thus, when sharing a bookmark within an organization, it is necessary to consider access authority unlike content sharing on the Internet.

The present invention has been made in view of such conventional problems, and the object of the present invention is to be effective and efficient while considering the access authority that is indispensable when sharing content within an organization. It is to provide an organization information retrieval system and an organization information retrieval program capable of sharing and retrieving contents.

In order to achieve the above object, the present invention provides an organization information search system for searching for content to be shared in a closed organization, wherein the organization information search system is a member for identifying a member in the organization. view ID, access rights which the members showing a viewing range that can be referenced content, and a first database that stores chromatic Yodo of the members, the content ID identifying the content, the location information of the content, the content access can refer members, a second database for storing at least including content additional information severity of the content, the member is applied to the content that matches the search conditions inputted to the client terminal using extract the access from the second database, the extracted con And access rights granted to Ntsu, the search executing means for specifying a content ID of the content to the access rights of the members that have been stored in the first database matches the string to a particular content ID in the search means The importance of the attached content is extracted from the second database, and part or all of the content additional information associated with the content ID is rearranged in order based on the extracted importance and the client Search result display means for displaying on the terminal, bookmark registration means for registering in the bookmark holder of the member when the input of bookmark registration is accepted from the client terminal among the contents displayed by the request from the client terminal, and the client terminal bookmarks from any member Upon receipt of the viewing reference request of Kuhoruda, said the members were viewing reference request from the client terminal, said in the case where the member that has received the viewing reference request does not match, the public flag of bookmarks holder that has received the viewing reference request Is set as information indicating disclosure, and when it is set as information indicating disclosure, the access authority of the content registered in the bookmark holder extracted from the second database, and the first if the access authority matches the databases members were previously stored the viewing reference request, and bookmarks display means for displaying the bookmark on the client terminal, the importance of the content, bookmark the content Calculated based on the number of members For each member, importance calculation means for calculating the usefulness and the number of contents registered by the member as bookmarks is provided.

  The internal organization information search program of the present invention is an internal organization information search program for causing a computer to realize functions such as creation registration / search / display of content to be shared among a plurality of members in an organization such as a company. The function of the in-organization information search system is realized by a computer.

  According to such an in-organization information search system and in-organization information search program, the importance of content is calculated by taking into account the usefulness of the member and the number of contents that the member has registered as a bookmark. The importance changes dynamically depending on the usefulness of the member and the bookmark registration status of the member, and a reliable importance is calculated. And since the content additional information of the content is displayed in the descending order of the importance of the content, in other words, the descending order of the content utilization by the member, the member who is the content searcher efficiently searches for the desired content. I can do it.

  Also, when the access authority of the client terminal member who requested the bookmark display or content display matches the access authority assigned to the content registered or requested to be displayed, the bookmark or content is displayed. Therefore, there is no fear that the member can know the content that the member cannot originally browse and refer to and the content additional information of the content.

  Further, the importance calculation means calculates the total number of members bookmarking the content for each content as the basic importance of the content, and for each member, the basic importance of all the content created and registered by the member The sum of the degrees is calculated as the usefulness of the member, and for each member, the usefulness of each member is divided by the number of the content that the member has bookmarked for all the members that have bookmarked the content. The sum of all members is updated as the importance level of the content, and for each member, the sum of the importance levels of all the contents created and registered by the member is updated as the usefulness level of the member. It repeatedly updates the importance of content, and the difference in usefulness before and after the update Difference between the importance of before and after the update are each to converge to a predetermined value may be updated of the usefulness and importance.

  According to this configuration, the usefulness of a member dynamically changes in accordance with the change in the importance of the content created and registered by the member, and the importance of the content also depends on the bookmark registration status of the content and the usefulness of the member. It changes dynamically according to the change. Furthermore, when the change converges, the usefulness and importance are adopted as reliable usefulness and importance, so that a more reliable search result is displayed.

  The search result display means may display the search results in descending order of the usefulness of the member who created and registered the content when the importance assigned to the searched content is 0.

  According to this configuration, even if the content has not been bookmarked, it is expected that the content created and registered by a highly useful member is more important. Therefore, the usefulness of the member who created and registered the content is expected. By sorting the search results of content in descending order, useful search results can be given to members who have searched for content.

In addition, when registering a bookmark of content, the bookmark registration unit registers the content additional information of the content to be bookmarked with a public flag indicating whether or not to disclose the content additional information to other members and registers it in the bookmark holder of the bookmark registered member. If the bookmark holder of any member is a bookmark holder of a member who uses the client terminal that requested the bookmark display, the bookmark display means stores all bookmarks created and registered in the bookmark holder. displaying said any member of bookmarks holder, if the bookmark holder is not a member who uses the client terminal, set as information disclosure flag of the content registered to the bookmark holder showing the public It was to display a bookmark if it is.

  According to this configuration, since the bookmark is displayed based on the presence / absence of the public flag, the privacy of the member is maintained when the other member does not want to know the bookmarked content.

Further, the bookmark registration means registers a pointer indicating a location where the content additional information of the content in the second database is stored in the bookmark holder when performing bookmark registration of the content . The information search system accesses the second database based on the pointer when displaying the content according to the request of the client terminal, and the access authority extracted from the content additional information in the second database; A match / mismatch with the access authority of the member using the client terminal may be confirmed.

  According to this configuration, the server does not directly access the database in which the content is created and registered and displays the content, but based on the pointer to the content additional information database registered in the bookmark holder. When the content additional information in the additional information database is accessed, the content is displayed when the access authority of the client terminal member who requested the bookmark display matches the access authority included in the content additional information. There is no fear that the member knows the content that the member cannot originally browse and refer to.

  Further, the bookmark registering unit registers a comment related to bookmark registration in the bookmark holder of the bookmark registering member when registering the bookmark of the content, and the bookmark display unit displays the comment. Also good.

  According to this configuration, by displaying a comment, it is possible to know what bookmark the displayed bookmark is and how it was bookmarked before the content is displayed. It can be used as a reference for searching for desired content.

  Further, the importance calculation means updates the importance of all the contents created and registered and the usefulness of all members in the organization, and then changes the bookmark registration contents to any one of the bookmark holders. If there is a change, only the importance of the content in the bookmark holder that has been changed and the usefulness of the member who created and / or registered the content may be updated.

According to this configuration, the importance of the content added / deleted as a bookmark and the usefulness of the member who created or registered the bookmark are updated, and recalculation is repeated until the content converges. This calculation can be performed efficiently in a short time without impairing reliability.

  According to the in-organization information search system and the in-organization information search program of the present invention, the importance of content is calculated by taking into account the usefulness of the member and the number of contents registered by the member. The importance changes dynamically depending on the usefulness of the member and the bookmark registration status of the member, and a reliable importance is calculated. And since the content additional information of the content is displayed in the descending order of the importance of the content, in other words, the descending order of the content utilization by the member, the member who is the content searcher efficiently searches for the desired content. I can do it.

Also, when the access authority of the client terminal member who requested the bookmark display or content display matches the access authority assigned to the content registered or requested to be displayed, the bookmark or content is displayed. Therefore, there is no fear that the member can know the content that the member cannot originally browse and refer to and the content additional information of the content.

  The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an overall configuration of an in-organization information search system according to the present invention. In the figure, a server 1 is connected to a plurality of client terminals 2 via a network 3 such as an in-house LAN or an in-house intranet.

  In FIG. 1, there are two client terminals 2, but in reality, a plurality of members in the organization create, register, and search for electronic documents (hereinafter referred to as contents) that should be shared within the organization such as a company. , There is a necessary number (for example, one for each member, or one for a plurality of members).

  The server 1 and the client terminal 2 each have a configuration (CPU not shown) necessary for executing and using a predetermined program including the in-organization information search program 1a and connecting to the network 3 to transmit / receive data. ROM, RAM, hard disk, communication means, input / output means, etc.), and any ordinary computer or server computer may be used.

  The hard disk included in the server 1 desirably has a large capacity because of the nature of the server, and the server 1 may include a management program such as database management software. Further, the server 1 may be configured by a plurality of servers connected via a network, depending on storage capacity and management.

  Further, the server 1 has an in-organization information search program 1a in addition to the general components as the server computer described above, and databases 1b to 1f used in these programs are also included in the server 1. . When the server 1 is composed of a plurality of servers connected via a network, the in-organization information search program 1a and the databases 1b to 1f may be distributed on different servers according to the processing load. Absent.

  Furthermore, the server 1 receives a content creation registration / search / browse reference (display) request from the client terminal 2 and transmits the processing result of the request to the client terminal 2.

  The network 3 may be the Internet in addition to an in-house LAN and an in-house intranet, or may have a dedicated line or other connection form (regardless of wired wireless).

  Authentication data and other communication data exchanged between the server 1 and the client terminal 2 via the network 3 are preferably encrypted in consideration of security problems. In this case, the server 1 and the client terminal 2 are encrypted. Each communication means and program includes an encryption means.

  In particular, for example, when the client terminal 2 is used at an employee's home or on a business trip and accesses the server 1 via the Internet, the risk of information leakage is higher than that of other networks. Data encryption is highly recommended. For encryption, a known method or means such as SSL (Secure Socket Layer) or VPN (Virtual Private Network) can be used.

  The in-organization information search program 1a is a component that plays a central role in the in-organization information search system of the present invention, and should be shared within the organization from each of the client terminals 2 used by a plurality of members in the organization such as a company. Processes content creation registration / change / deletion requests, content search / browse reference (display) requests, bookmark registration / change / delete requests, bookmark browsing reference (display) requests. Is a program for managing data such as content to be shared, content additional information, search index, and bookmark holder in association with each other.

  The in-organization information search program 1a may be configured not only to operate on the server 1 but also on each client terminal 2, or on both the server 1 and the client terminal 2. It may be configured to operate. Further, middleware may operate on the OS of the server 1 and the client terminal 2, and what is installed on the server 1 may operate on the web browser of the client terminal 2.

  Further, for example, when the organization information search program 1a includes a program for generating display data of a Web page, the client terminal 2 uses a known Web browser program included in its own terminal to display the Web page. Although it will be used, it is conceivable that some functions of the in-organization program 1a, such as a form printing program, are incorporated in the client terminal 2 in advance as a program that complements the Web browser program.

  2 and 3 are diagrams showing a detailed configuration of the in-organization information search program 1a. The in-organization information search program 1a is mainly used for a maintenance function executed automatically by a server 1 at a timing intended by an administrator of the in-organization information search system 1 or an operation from the client terminal 2. The client function executed based on the program can be realized by reading and executing the program by hardware (computer).

  FIG. 2 shows the configuration of a maintenance program for realizing the maintenance function and the databases 1b to 1f in which data is read and written by the function realized by the maintenance program.

  As shown in FIG. 2, the means for realizing the maintenance function by hardware includes member additional information registration / updating means 10, content fetching means 11, index creating means 12, content additional information registration / updating means 13, importance calculation. It consists of means 14.

  FIG. 3 shows the configuration of a client program for realizing the client function and the databases 1b to 1f from which data is read and written by the function realized by the client program. The databases 1b to 1f are the same as those shown in FIG.

  As shown in FIG. 3, the hardware means for realizing the client function includes a login unit 20, a content registration unit 21, a search execution unit 22, a search result display unit 23, a content display unit 24, a bookmark registration unit 25, It comprises bookmark display means 26.

  Hereinafter, the details of each means in the in-organization information search program 1a will be described together with the detailed description of data stored in each of the databases 1b to 1f.

  When the member starts using the in-organization information search system using the client terminal 2, the login unit 20 displays a login screen on the client terminal 2 of the member and accepts input of the member ID and password. Then, the authentication process is performed based on the comparison with the member data stored in the server 1, and after the member authentication process is completed, the client terminal 2 performs various processes (in this embodiment, content creation registration, search execution, bookmark A main screen (not shown) for selecting (display) is displayed, and content registration means 21, search execution means 22, and bookmark display means 26 to be described later are called in accordance with various processing selection instructions from the client terminal 2.

  The screen such as the main screen is an ASP type in which the organization information search program 1a is installed in the server 1, and it is assumed that the processing content is displayed on the Web browser of the client terminal 2, and the screen is redisplayed. The button for closing the screen and the function for uploading and downloading data use the functions of the Web browser or operating system, but the screen does not necessarily have to be displayed by the Web browser, and the Web browser and operating system The function need not be used.

  The server 1 prevents the leakage of data stored in the server 1 by preventing the use of the organization information search system by an unauthorized member who is not given the member ID and password by performing the login process of the member. I can do it.

  Note that the member ID and password are assigned to each member in advance and are stored in a member database (not shown). The member database may be an existing database in the organization. In addition to the member ID and password, member information such as a member name, department name, and access authority may be stored in association with each other.

  The password is preferably encrypted and stored in the server 1 in consideration of security. Further, it is desirable that means for displaying a password change screen (not shown) and changing the password by the member himself / herself is provided in the in-organization information search management program 1a.

  Furthermore, the log-in means 20 of the present embodiment extracts member additional information recorded in association with the member ID of the logged-in member from the member additional information database 1b after the authentication is completed.

  The member additional information is data including at least identification information (member ID) that can identify a member who uses the in-organization information search system.

  The member additional information registration / updating means 10 is a means for registering and updating this member additional information in the member additional information database 1b.

  The member additional information of the present embodiment includes a member ID, an access authority indicating a range in which the member can browse the content, a pointer to the bookmark holder of the member, and the member creating, registering and browsing the useful content. It is a record in which a value is recorded in each item of usefulness indicating the degree of whether or not.

  For example, in the access authority item, member attributes (for example, department status: 1, department manager: 2, supervisor: 3, others: status within the organization, level of processing authority, department, etc.) are recorded. Is done.

  Although details of the bookmark holder and usefulness will be described later, in the usefulness item, “0” is recorded in the initial state and in the state where the bookmark is not registered, and the importance calculation means 14 described later is useful. When calculating the degree, the member additional information registration / updating means 10 updates the value based on the calculation result of the importance degree calculating means 14.

  Further, the member additional information database 1b and the previous member database may be integrated, and in this case, a password or the like is added to the item of member additional information. The member additional information may include a member name or the like.

  As described above, when the member database and the member additional information database 1b are integrated, the login unit 20 directly refers to the data stored in the member additional information database 1b for the authentication process. If they are not integrated, both databases have a common key such as a member ID to search for member additional information related to member data in the member database from the member additional information database 1b. There is a need.

  The content registration unit 21 displays a content registration screen (not shown) on the client terminal 2, and the content created by the members in the organization, that is, an electronic document (plain text, HTML, Word, Excel, Powerpoint, PDF, etc.) The office system format, multimedia electronic files such as sound and images) are stored in the search target content database 1c placed on the server 1. In the present specification, the process of storing the created content in the search target content database 1c is referred to as “content creation registration”.

  The search target content database 1c is a common electronic document storage used in the organization, and need not be a storage prepared specifically for the present invention. Therefore, in general, file servers, groupware, intranet Web servers, document management systems, RDBMS, and the like that are already used in the organization are used. There may be a plurality of different types.

  Further, when creating and registering content, the content registration means 21 accepts designation of access authority (member ID or access authority of a member who can browse the content) from the client terminal 2 of the member, and this access authority information Is associated with the content and recorded.

  If the access authority information can be recorded as header information of the content, such as office format, there is no need to specify it. However, there is a database that links the contents and access authority information by ignoring the header information. It may be prepared separately.

  Further, the recording format of the access authority recorded as the content additional information may be a list of member IDs, the same type of information as the access authority recorded as the member additional information, or includes a plurality of member IDs. (For example, group according to position within the organization such as department manager class, section manager class, group according to department such as sales department, engineering department, etc.) )

  Also, in this header information, the values of various items such as the member name that created and registered the content, the member ID of the member, the content creation registration date, the content file name, and the file format are recorded. It will be used when registering additional information.

  The content registration means 21 can not only create and register content but also delete the already created content and change the content file name and access authority. Of course, these deletions and changes are later reflected in the update of the content additional information in the content additional information registration / updating means 13.

  The content fetching unit 11 is a unit that fetches the content created and registered by the content registration unit 21 from the search target content database 1c and extracts content additional information from the content header information and the like. be called.

  The content is taken in periodically, for example, once a day. This may be such that the content fetching means is automatically activated at the time designated by the timer, or the content fetching means is activated by the operation of the administrator of the in-house information search system. It may be.

  In addition, an enormous amount of content is accumulated in the search target content database 1c, and in order to avoid duplication, for example, content within a range specified based on the content creation registration date in the content header information, or changes Make sure that only the content that was found is captured.

  Here, the content additional information is data including at least identification information (content ID) that can identify the content in the search target content database 1c.

  The content additional information registration / updating means 13 is means for registering and updating the content additional information in the content additional information database 1d.

  The content additional information of the present embodiment includes content ID, content location information (also referred to as a URI and content storage location in the search target content database 1c), access authority (access authority of members who can display / view the content), This is a record in which a value is recorded in each item of the member ID of the member who has registered and created the content, and the importance indicating the degree of utilization of the content by the members in the organization.

  The content ID is given to the content when the content additional information registration / updating means 13 registers the content additional information of the new content. The content ID may be assigned when the content registration unit 21 creates and registers content in the search target content database 1c. In addition, when the target content to be registered with the bookmark is not yet captured by the content capturing unit 11, that is, when it is not crawled and does not yet have the content additional information, the content additional information is newly added for the content. The content ID may be assigned simultaneously with the generation.

  In addition, the content additional information may include a content creation registration date, a content file name, and the like. Although the details of the importance of the content will be described later, in the initial state and in the state where the bookmark is not registered, “0” is recorded in the importance item, and the importance calculation means 14 described later determines the importance. At the time of calculation, the content additional information registration / updating means 13 updates the value based on the calculation result of the importance degree calculating means 14.

  The content additional information, except for the importance item, is registered and updated in the content additional information database 1d as it is extracted from the content by the content fetching means 11. In the case where information other than the member ID, such as the member name, is extracted from the content, another database (for example, member additional information) in which the member ID is associated with the member name is extracted. It is desirable to convert it into a member ID with reference to the database 1b or member database.

  The index creating means 12 extracts a keyword from the file name / text of the content fetched by the content fetching means 11 to create a content search index, and links the content ID to the search index database 1e. It is a means of recording.

  In addition, in the search index database 1e, in addition to a character string extracted from a file name or text of a body, a so-called keyword, content additional information itself may be recorded as one type of keyword. As a result, not only general word search but also content creation registrant search, content creation registration date search, etc. can be performed at the time of content search described later.

  The search execution means 22 displays a search screen (not shown) on the client terminal 2, receives an input of a search expression from the client terminal 2, and selects content that matches the input search condition based on the input search expression. This is a means for searching from the search index database 1e and delivering the value of the content ID of the content as the search result to the search result display means 23.

  The search result display means 23 displays a search result display screen (not shown) on the client terminal 2, and the content search result based on the content additional information associated with the content ID handed over from the search execution means 22. It is means for displaying a list on the client terminal 2. The search result list displays a part or all of the content additional information.

  The content display unit 24 displays a content display screen (not shown) on the client terminal 2, and in the content additional information associated with the content ID delivered from the search result display unit 23 by an operation from the client terminal 2. This is means for displaying the content itself on the client terminal 2 based on the URI (content position information).

  When displaying the content itself, the content display means accesses the content additional information database 1d, extracts the URI (content position information) from the content additional information associated with the delivered content ID, and extracts it. Based on the URI, the search target content database 1c is accessed and the content is displayed on the client terminal 2.

  Further, as will be described later, the content display unit 24 accesses the content additional information database 1d based on the pointer value to the content additional information database 1d delivered from the bookmark display unit 26 by an operation from the client terminal 2. Then, the URI of the bookmarked content can be extracted and the content can be displayed in the same manner as described above.

  There is a possibility that the bookmark registration means 25 is frequently browsed and referenced by members who use the client terminal 2 (logged in) out of the contents displayed by the content display means 24 based on an operation from the client terminal 2. A content is registered as a bookmark, a pointer for accessing content additional information associated with the content ID of the content to be registered in the bookmark holder provided for each member in the bookmark holder database 1f, It is means for recording a bookmark disclosure flag indicating whether or not to disclose to a member, and a comment by a member who has performed bookmark registration.

  Further, the bookmark registration means 25 also deletes a bookmark once registered from the bookmark holder or changes the recorded contents (bookmark release flag, comment) of the bookmark holder based on an operation from the client terminal 2.

  In the bookmark holder of this embodiment, not a content ID but a pointer for accessing content additional information of the content registered in the bookmark in the content additional information database 1d is recorded.

  This is because, as will be described later, when the content display unit 24 displays the bookmarked content, whether or not to display is determined based on the access authority given to the content. This is because if the content ID itself is recorded, the search target content database 1c can be directly accessed, and the content may be displayed without considering the access authority.

  The bookmark holder is preferably created in advance for each member ID of the member, and is associated with the member ID. Moreover, the bookmark holder does not necessarily need to be created for each member ID, and a bookmark holder for a group of a plurality of members (for example, a department to which a sales department belongs) may be created. In this case, the bookmark holder is associated with the member IDs of all members included in the group, and the bookmark holder can be shared between the groups.

  The bookmark display means 26 displays a bookmark display screen (not shown) on the client terminal 2, and the content additional information is based on the pointer of the content additional information database 1d recorded in the bookmark holder in the bookmark holder database 1f. This is a means for accessing the database 1d, extracting a part or all of the content additional information of the bookmarked content from the content additional information database 1d and displaying it as a bookmark list.

  Hereinafter, displaying the bookmark list by the bookmark display means 26 may be referred to as “displaying a bookmark”.

  The bookmark display means 26 can also display the comment recorded in the bookmark holder along with the content additional information. By displaying the comment, it is possible to know what the bookmark being displayed is, and how the bookmark has been bookmarked before the content display means 24 displays the content, This is a reference for searching for the desired content.

  The content display unit 24 accesses the content additional information in the content additional information database 1d on the basis of the pointer to the content additional information database 1d delivered from the bookmark display unit 26, and stores the content having the content additional information. It is also possible to display on the client terminal 2.

  The importance level calculation means 14 is a means for calculating the importance level of the content and the usefulness level of the members based on the recorded contents of the bookmark holder stored in the bookmark holder database 1f.

  The importance level calculation means 14 determines the importance levels of all contents created and registered, and all members in the organization at the timing intended by the administrator of the in-organization information search system or automatically by the server 1 at predetermined intervals. The member additional information registration / updating means 10 calculates the usefulness of the member additional information in the member additional information database 1b, and the content additional information registration / updating means 13 determines the importance of the content additional information in the content additional information database 1d. Update each degree.

  Here, the characteristic part of this invention is demonstrated in detail hereafter. First, when the bookmark display means 26 displays the URI of the bookmarked content and the comment recorded at the time of bookmarking based on the bookmark browsing reference request from the client terminal 2, it is stored in the bookmark holder. The bookmark is displayed based on the public / private flag of the bookmark holder in question and the access authority of the member using the client terminal 2 that has made the bookmark browsing reference request.

  Specifically, when a public flag is set in the bookmark holder that has been requested to be browsed from the client terminal 2, the access authority of the member logged in from the login means 20, and the bookmark holder that the member wants to browse and browse If the access authority in the content additional information of the content matches, the bookmark is displayed.

  As described above, since the bookmark is displayed based on the presence / absence of the public flag, the privacy of the member is maintained when it is not desired to know what the bookmarked content is.

  When the content display unit 24 and the bookmark display unit 26 access the content additional information in the content additional information database 1d based on the pointer to the content additional information database 1d recorded in the bookmark holder, the bookmark and the bookmark Since the bookmark and the content are displayed when the access authority of the member using the client terminal 2 who has requested to browse the registered content matches the access authority included in the content additional information, the member is displayed. However, there is no fear that the member knows the content additional information of the content that cannot be browsed and the comment of the bookmark.

  The second feature of the present invention is that the search result display means 23 displays a list of content search results based on the importance level of the content calculated by the importance level calculation means 14.

  Specifically, the search result display means 23 acquires the importance in the content additional information of the content included in the search result from the content additional information database 1d, and sends the search result list to the client terminal 2 in descending order of importance. Is displayed.

  In this way, the content additional information of the content is displayed in descending order of importance of the content, in other words, in descending order of utilization by the member, so that the member who is a content searcher efficiently searches for the desired content. I can do it.

  The third feature of the present invention resides in the importance and usefulness calculation method by the importance calculation means 14. The following description will be specifically made with reference to the flowchart of the importance / usefulness calculation method in FIG. 4 and the relationship diagram of members, contents, and bookmarks in FIG.

  FIG. 5 shows four members A to D using the in-organization information search system, and contents A-1 to A-4 to be shared within the organization, which are created and registered by the members in the search target content database 1c. Relationships between B-1 to B-3, C-1 to C-3, and D-1 to D-4 are shown.

  In FIG. 5, solid arrows indicate the relationship between each member A to D and the content created and registered by each member, and dotted arrows indicate each member A to D and the content each bookmark registered from the bookmark registration means 25. Represents the relationship. Note that bookmark registration can be performed not only on content created and registered by other members, but also on content created and registered by itself.

  For example, in FIG. 5, there are a total of four contents A-1 to A-4 created and registered by the member A, and the number of contents registered by the member A is A-2, B-1, and C-2. It can be seen that there are a total of three.

  Similarly, the content created and registered by member B is three in total, B-1 to B-3, and the number of content that member B has bookmark-registered is two in total, A-2 and A-4. I understand.

  Similarly, there are a total of three contents C-1 to C-3 created and registered by the member C, and the total number of contents registered by the member C is two, A-2 and B-3. I understand.

  Similarly, there are a total of four contents D-1 to D-4 created and registered by member D, and a total of three contents A-4, C-2, and D-2 are registered by member D as bookmarks. It turns out that it is.

  Based on the premise as described above, the importance level calculation unit 14 requests the content additional information registration / updating unit 13 to update registration of the importance levels of all the contents that are currently created and registered (S100).

  The importance level of the content is the total number of members who bookmarked the content only when it is calculated for the first time in the in-house information search system, and this is called the basic importance level of the content. Here, the basic importance of the content is calculated based on the number of bookmarks registered. The content is bookmarked by many members. This means that the content is attracting attention or used by more members. This means that the importance of the content is high. The basic importance of each content is a number shown in the content frame in FIG.

  As described above, the search result display unit 23 displays the search results in descending order of importance of the content. Since the content bookmarked by many members has a higher importance level, the higher the importance level of the content means that the content is more utilized.

  However, the basic importance of the content obtained at this stage is merely the total number of bookmark registrations, and it is not considered which member registered the bookmark. That is, the basic importance does not depend on individual members and is not weighted differently depending on the members.

  However, if different weights are not given to each member, it is assumed that all of their own contents are registered as bookmarks in order to increase the importance of the contents created and registered by themselves. It ’s hard to say. In addition, since the amount of content creation / registration, quality creation / registration status, utilization status, and system usage status vary depending on the member, the importance of content is originally calculated considering these statuses of the member. Should.

  Therefore, in the present invention, the importance of content is calculated in consideration of the usefulness of each member and the number of contents registered by the member as bookmarks. In other words, the importance of the content is calculated by taking into account the usefulness of the member and the number of content that the member has registered as a bookmark. Therefore, the degree of reliability is calculated dynamically.

  Here, after S100, the importance calculation unit 14 requests the member additional information registration update unit 10 to update registration of the usefulness levels of all members at the present time (S110).

  The usefulness of a member is the sum of the importance of all contents created and registered by the member. The fact that the content created and registered by the member has a large number of bookmarks registered means that the content is attracting attention or used by more members, that is, the member creates and registers content with higher importance. This means that the probability of doing is high.

  In FIG. 5, for example, the usefulness of the member A is that the usefulness of the content A-2 is 3 and the importance of the content A-4 is 2 among the 4 contents created and registered by the member A. 3 + 2 = 5. Similarly, the importance of member B is 2, the usefulness of member C is 3, and the usefulness of member D is 1. When the step of S110 is executed for the first time, S110 is a step for obtaining the sum of the basic importance of the content obtained previously.

  Then, the importance level calculation means 14 determines the importance level of the content based on the usefulness of the member who bookmarked the content and the number of the content registered by the member for each content. Update. Specifically, for each member who bookmarks the content, the usefulness of the member is divided by the number of contents registered by the member, and this is added for all the members (S120).

  For example, the second content from the upper level created and registered by member A in FIG. 5 is bookmarked from member A, member B, and member C. In this case, the importance of the content is 5/3 + 2/2 + 2/2.

  That is, here, the importance of the content is not simply set as the number of bookmarked members × 1, but the weight of the members is reflected by obtaining the sum of the numerical values different for each member.

  Thus, by dividing the usefulness of a member by the number of bookmark registrations and adding it to the importance of each bookmarked content, the usefulness of the member can be reflected evenly on the importance of each content. .

  For example, a member who has a high degree of usefulness but has a small number of content that he / she has bookmarked is recognized by other members as creating and registering useful content, and himself / herself is Since the bookmark is carefully registered for the content that is particularly necessary without registering the bookmark indiscriminately, the influence on the importance of the content of the member can be said to be great. Therefore, the weight (usefulness) of this member is set high, and the importance of the content is also high.

  On the other hand, members who have a low level of usefulness but have a large number of content that they have bookmarked are not recognized by other members as creating and registering useful content, and Since the content tends to be bookmarked even for content that is not so important, it can be said that the influence on the importance of the content of the member is small. Therefore, the weight (usefulness) of this member is set low, and the importance of the content is also low.

  In this way, by assigning weights to all members who have bookmarked a certain content and calculating the sum of the weights, this sum is updated as the importance of the content, that is, the new importance of the content is calculated. Is done.

  As the importance of the content is updated, that is, as the new importance is calculated, the usefulness of the member is naturally recalculated (updated) (S130). Since the usefulness of the member is the sum of the importance of the contents created and registered by the member, the new usefulness of the member is the sum of the new importance of the contents.

  As described above, in the present invention, the usefulness of a member dynamically changes according to the creation / registration status of the content created and registered by the member and the importance of the content, and the importance of the content also changes. It changes dynamically according to the bookmark registration status of the content and the change of the usefulness of the member.

  Furthermore, the present invention not only dynamically changes the importance of the content and the usefulness of the members, but the usefulness and the importance become the final usefulness when the change of the importance and the usefulness converges. The feature is that it is adopted as the importance.

  That is, when the new usefulness of the member and the new importance of the content are calculated, the difference between the usefulness before and after the update and the importance are calculated (S140).

  After calculating the difference (change) between the importance (usefulness) and the new importance (new importance), the importance of the content and the usefulness of the members are changed to the previous new importance and new usefulness respectively. Update (S150).

  Then, it is determined whether the larger one of the two differences (changes) obtained in S140 is sufficiently smaller than a predetermined value (K) determined in advance (S160).

  That is, the importance calculation means 14 repeatedly updates (recalculates) the usefulness of the member and the importance of the content, and the difference in usefulness before and after the update and the difference in importance before and after the update each converge within a predetermined value. Until it is done, the usefulness and importance are updated.

  Here, if the difference is not sufficiently small, the new usefulness of the member and / or the new importance of the content at the present time have not converged, and it cannot be said that the new importance is stable and reliable. Even if the search result list is displayed using such importance, there is a possibility that the search result list is not effective.

  Therefore, if the new usefulness of the member and the new importance of the content do not converge, that is, until the difference becomes sufficiently small with respect to the predetermined value (K), that is, until the convergence, the process returns to S120 and is useful. When the degree and the importance are recalculated and converged, finally, the usefulness and importance that are effective and reliable for displaying the search result list are obtained.

  As described above, according to the present invention, the importance level of the content is not only calculated based on the usefulness level of the member, but also dynamically changes depending on the bookmark registration status in the content and the change of the usefulness level of the member. Further, when the change converges, the importance is adopted as the reliability importance, so that a more reliable search result list is displayed.

  Conventionally, when sharing a bookmark on the Internet or the like, it is impossible to assign different weights to each user or content creation registrant due to the anonymity of Internet users and content creation registrants. Even if there is a link between contents, there is no link between the contents and people, and the importance of the contents can only be calculated based on the number of accesses to the contents.

  However, in the in-house information retrieval system of the present invention, it is clear who the system user and content creation / registration person is. For example, if employee A creates and registers content S and employee B bookmarks the content S, here, employee A → content S → employee B, so to speak, content (content ID) and member (member) ID) is formed. This link between the content and the member demands more effective and reliable content importance and member usefulness.

Furthermore, unlike the Internet environment in which an unspecified number of contents can be shared, the contents created and registered in the information retrieval system within the organization are, of course, limited to use within a closed organization, and the contents are created. Since registrants are also limited to members within the organization, when changing the importance of content and the usefulness of members to more reliable ones, calculation of convergence of importance and usefulness impossible in the Internet environment Is possible.

  Hereinafter, using the in-house information search system of the present invention, a plurality of employees in a certain company share the created and registered content within the company, search for content, browse reference, bookmark registration, bookmark browse reference A detailed embodiment in the case of performing the above will be described based on the flowcharts of FIGS. 6 to 8 and the configuration diagrams of FIGS.

  In addition, it is assumed that data stored in the databases 1b to 1f are already recorded and accumulated in the server 1 when the employee uses the system.

  In addition, the content registration unit 21 creates and registers content to be shared within the company in the search target content database 1c based on the operation of each employee from the client terminal 2.

  The content fetching unit 11 fetches the content created and registered in the search target content database 1c periodically, for example, once a day, outside the working hours of the employee, and adds content from the header information of the content. Information is extracted and delivered to the content additional information registration / updating means 13, the content additional information is recorded in the content additional information database 1 d, or the captured content and content additional information are delivered to the index creating means 12 to create a search index Then, the search index is recorded in the search index database 1e.

  The content is identified by the content ID, and the data in the search target content database 1c, the content additional information database 1d, and the search index database 1e all include the content ID. The search index database 1e can access the search target content database 1c only through the content additional information database 1d. This is because the presence or absence of display changes based on the access authority in the content additional information database 1d when displaying the content search result or the content itself.

  For the same reason, the content ID is not recorded in the bookmark holder database 1f, and a pointer to the content additional information database 1d for accessing the content additional information of the bookmarked content is recorded. Become. Similarly to the bookmark holder database 1f, a pointer to the content additional information database 1d may be recorded in the search index database 1e.

  Further, the member additional information registration / updating means 10 creates member additional information for each employee in advance and records it in the member additional information database 1b. The case of new registration or change of member additional information will be dealt with each time.

  The importance level calculation means 14 calculates the importance level of the content and the usefulness level of the employee based on the data stored in the content additional information database 1d, the member additional information database 1b, and the bookmark holder database 1f. The registration update unit 13 and the member additional information registration update unit 10 are requested to update registration of importance and usefulness. The flow of importance and usefulness calculation is as described with reference to FIGS.

The employee member ID and password are stored in a member database (not shown).

  The login means 20 of the in-organization information search program 1a displays a login screen (not shown) on the employee's client terminal 2 and accepts the input of the employee's member ID and password. Therefore, when the employee inputs the member ID and password on the login screen and clicks the login button with the mouse, the login means 20 uses the entered member ID value as a key to search the member ID from the member database. The member data whose value matches the key is read, and it is checked whether or not the input password value matches the password of the read member data.

  Here, when there is no member data that matches the key or when the password does not match, the login unit 20 displays an error message or the like on the client terminal 2 and prompts the user to input the login ID and password again. When the login ID and the password match, the login unit 20 acquires the member ID of the employee and permits the use of the organization information search system of the employee (S200).

  Further, the login unit 20 extracts the member additional information corresponding to the member ID from the member additional information database 1b based on the member ID acquired in S200, and stores it in the temporary memory (S210). Note that it is not always necessary to store all of the member additional information in the temporary memory at this login stage, and the member additional information database 1b is accessed and extracted as necessary. Also good.

  The employee who is permitted to use the in-organization information search system by the login unit 20 is hereinafter referred to as an employee who is logged in. Hereinafter, the client terminal 2 appearing in the embodiment is a client terminal used by a logged-in employee.

  The log-in means 20 displays a main screen (not shown) that allows the client terminal 2 to select various processes (in this embodiment, content creation registration, search execution, bookmark display), and selects various processes from the client terminal 2. In accordance with the instruction, the content registration means 21, search execution means 22, and bookmark display means 26 can be called.

  Here, when the client terminal 2 selects search execution, the login unit 20 calls the search execution unit 22 and displays a search screen (not shown) on the client terminal 2. The client terminal 2 inputs a search expression in the search expression input field on the search screen. Then, the search execution means 22 acquires the input search formula (S220).

  The search execution means 22 searches the search index database 1e for content that matches the previously obtained search expression. Next, the content ID of the searched content is extracted from the search index database 1e, and the access authority given to the content having the content ID is extracted from the content additional information database 1d based on the content ID. Further, based on the member ID of the employee logged in from the login means 20, the access authority of the employee having the member ID is extracted from the member additional information database 1b.

  Then, it is determined whether or not the access authority of the content extracted in this way matches the access authority of the logged-in employee (S230).

  In this way, the content having the same access authority becomes the search result in the search execution means 22, and the content ID of the content is delivered to the search result display means 23. Then, the search result display means 23 acquires the content additional information associated with the content ID from the content additional information database 1d based on the content ID of the content (S240).

  The search result display unit 23 rearranges the contents in descending order of importance based on the importance of the contents included in the acquired content additional information (S250). Then, content additional information of the content is displayed on the search result display screen (not shown) of the client terminal 2 in the rearranged order (S260). The content additional information displayed in the present embodiment is a URI (content location information), access authority, member ID of the content creation registrant, and importance of the content.

  In this way, content search is performed based on both the search formula and the match / non-match of the access authority of the logged-in employee and the access authority granted to the content. Even when the search result is displayed, only the content additional information of the content that the searcher can originally browse and display is displayed.

  Therefore, if the content does not match the access authority, for example, the logged-in employee only has the access authority as a general employee, but the content itself can be browsed and browsed by the person with the access authority as the general manager. In addition, there is no worry about the additional information of the content being known to general employees.

  In addition, since the search results are displayed in descending order of the importance of the content, the logged-in employee can efficiently search for the desired content.

  After the search result is displayed, when it is desired to browse and refer to the actual content based on the displayed content additional information, the client terminal 2 specifies the URI of the content to be browsed and referenced from the input unit. The display unit 24 accesses the specified URI in the search target content database 1c, and displays the content in the URI on the client terminal 2 (S270).

  If it is desired to register the displayed content as a bookmark (S280), the process proceeds to the bookmark registration flow of FIG.

  When the client terminal 2 wants to bookmark-register the content displayed by the content display means 24, the bookmark registration means 25 receives the input from the input means such as a keyboard, and the member additional information database A pointer to the bookmark holder associated with the member ID of the logged-in employee is acquired from the member additional information in 1b, and the bookmark holder of the employee in the bookmark holder database 1f is accessed (S600).

  The member ID is a member ID input in advance when the client terminal 2 logs in with the login unit 20.

  Next, the client terminal 2 determines whether or not to open the bookmark to be registered to other members, and sets the bookmark public flag to ON (public) or OFF (non-public) from the input means. Such information is input (S610). In response to the input, the bookmark registration unit 25 writes the value of the public flag in the bookmark holder accessed earlier.

  The bookmark registration unit 25 acquires a pointer to content additional information corresponding to the content ID of the content displayed on the client terminal 2 by the content display unit 24 from the content additional information database 1d, and uses the pointer as a bookmark holder. Write (S620).

  In this flowchart, whether or not to publish is set for the entire bookmark holder, but whether or not to publish may be set for each bookmark holder in the bookmark holder. . In that case, the pointer to the content additional information of the content to be bookmarked and the value of the public flag are written in the bookmark holder in association with each other.

  In addition, when setting whether or not to open the entire bookmark holder as in this embodiment, it is not necessary to go through S610 every time a bookmark is registered, and whether or not to open is set or changed as necessary. Also good.

  The display of the client terminal 2 returns to a search result display screen (not shown), and if there is other content to be browsed, the content display means 24 is requested to display the content. If the displayed content is to be bookmarked, bookmark registration is performed in the same manner as before.

If the logged-in employee wants to search using another search formula (S290), the search means displays a search screen on the client terminal 2 and accepts the input of the search formula (S220). Repeat step S260.

  Next, the flow in the case where the logged-in employee performs browsing reference to the bookmark will be described based on the flowchart of FIG. As a premise of the flowchart of FIG. 8, it is necessary that the log-in means 20 permits the authentication of the employee as in the case of content search (S200 in FIG. 6).

  The bookmark display means 26 receives a browsing reference command for a bookmark holder of a specific member from the client terminal 2, accesses the bookmark holder database 1 f, and bookmark holder associated with the member ID of the member designated from the client terminal 2. Is read (S300).

  Here, it is confirmed whether or not the read bookmark holder belongs to the logged-in employee (S310). As a confirmation method, it is only necessary to confirm whether or not the member ID of the owner of the read bookmark holder matches the member ID of the logged-in employee. The member ID of the logged-in employee is the member ID input when logging in by the login means 20.

  If the member ID of the owner of the bookmark holder does not match the member ID of the logged-in employee, that is, if the bookmark holder does not belong to the logged-in employee, the value of the public flag recorded in the read bookmark holder is It is determined whether it is ON or OFF (S320).

  If the public flag is ON, this bookmark holder indicates that it is a public bookmark holder, and the bookmark in the bookmark holder is read (S330). Specifically, the bookmark display means 26 reads a pointer to the content additional information of the content recorded in the bookmark holder.

  Then, the bookmark display means 26 accesses the content additional information database 1d based on the pointer to the content additional information, extracts the access authority included in the content additional information of the access destination, and this is the member of the logged-in employee It is determined whether or not it matches the access authority included in the member additional information associated with the ID (S340).

  If they match, the content additional information of the content having this content ID may be browsed and referred to by the logged-in employee. Therefore, the URI (content location information) extracted from the content additional information and In the bookmark holder, a comment recorded in association with the previous pointer is set and displayed as a bookmark on the client terminal 2 (S350).

  If there is still a bookmark in the bookmark holder (S360), the process returns to S330, and steps S330 to S350 are repeated.

  If the member ID of the owner of the bookmark holder matches the member ID of the logged-in employee in S310, that is, if the bookmark holder to be browsed is the bookmark holder of the logged-in employee itself, S320. This step is skipped, and the process proceeds to step S330 without confirming whether the disclosure flag is ON or OFF.

  If there are other bookmark holders to be browsed (S370), the process returns to S300, and ends when the bookmark holder to be browsed is terminated.

  As described above, when displaying a bookmark, as in the case of displaying the search result of the content, the access authority given to the content matches the access authority of the member who uses the client terminal 2 that wants to display the bookmark. Since the bookmark is displayed only when it is confirmed whether or not it matches, there is no concern that a bookmark that should not be known is displayed.

Moreover, since it is possible to set whether to make a bookmark public or private for each bookmark holder, the privacy of the member having the bookmark holder is maintained.

  Another embodiment of the organization information retrieval system of the present invention will be described below. The difference between this embodiment and the previous embodiment lies in the importance and usefulness calculation method of the importance calculation means 14.

  The importance and usefulness calculation method in this embodiment is characterized in that, after calculating the importance of all contents and the usefulness of all members, there is a change in the contents stored in the bookmark holder (that is, the bookmark is Newly registered or existing bookmarks are deleted), the content related to the changed bookmark and the member related to the content, that is, the content is limited to the changed range. The recalculation of importance and usefulness is performed only for members registered and / or bookmarked.

  By configuring in this way, it is not necessary to recalculate the importance and usefulness for every content and every member every time, and the efficiency of the processing of the in-organization information retrieval program 1a can be improved.

  A specific embodiment will be described below with reference to the flowchart of FIG. The flowchart of FIG. 9 replaces the steps S120 to S160 of FIG. Since the flow other than the importance and usefulness calculation and the configuration other than the importance calculation means 14 are the same as those in the previous embodiment, the description thereof will be omitted.

  As a premise for calculating importance and usefulness in this embodiment, a data area for a recalculation flag (ON, OFF) is newly provided for each of the member additional information and the content additional information. Note that the value of the recalculation flag is all recorded as OFF in the initial state.

  When registering or deleting a bookmark, the bookmark registering means 25 delivers the pointer of the bookmark holder (which member's bookmark holder) to which the registered or deleted bookmark belongs to the content additional information registration updating means 13.

  The content additional information registration updating means 13 accesses the bookmark holder in the bookmark holder database 1f based on the received bookmark holder pointer, and further, based on the pointer of the content additional information recorded in the bookmark holder, The content additional information database 1d is accessed, and the recalculation flag of the content additional information of all the contents registered as bookmarks is turned ON (S400).

  The importance calculation means 14 calculates the new importance of the content only for the content for which the recalculation flag is ON. The new importance calculation method is the same as S120 in FIG. 4, and for each member who bookmarks the content, the usefulness of the member is divided by the number of contents registered by the member and bookmarked. Add for all members.

  When the recalculation of the new importance level of the content is completed, the content additional information registration / updating unit 13 turns off the recalculation flag of the content (S420).

  The importance level calculation means 14 compares the new importance level of the content calculated in S410 with the importance level recorded as the content additional information of the content, and the content creation registration of the content whose difference is equal to or greater than a predetermined value K The recalculation flag of the member additional information of the user (recorded as one item of the content additional information) is turned ON (S430). Also, the importance level is updated with the new importance level.

  Here, if the recalculation flag of the member additional information is ON (S440), the importance calculation means 14 recalculates the new usefulness only for the member whose recalculation flag is ON (S440). S450). The method for calculating the new usefulness of the member is the same as S130 in FIG. 4, and is obtained as the sum of the new importance of the content.

  When the recalculation of the member's new usefulness is completed, the member additional information registration / updating means 10 turns off the recalculation flag of the member (S460).

  The importance calculation means 14 compares the new usefulness of the member calculated in S450 with the usefulness recorded as the member additional information of the member, and if the difference is equal to or greater than a predetermined value K, the importance of the member The recalculation flag in the content additional information of all the contents registered as bookmarks in the bookmark holder is turned ON (S470). Also, the usefulness is replaced with a new usefulness.

  If the recalculation flag of the content additional information is ON (S480), the importance calculation means 14 returns to S410 and recalculates the new importance only for the content for which the recalculation flag is ON.

  In this way, steps S410 to 480 are repeated until the recalculation flags of all contents and all members are turned off.

  As described above, in this embodiment, when recalculating the usefulness of content and members, the new importance is calculated only for the content that has been added to or deleted from the bookmark holder. At this time, if the difference between the new importance level and the importance level (old importance level) is larger than K, the importance level of the content has not converged, and it cannot be said that the importance level is a reliable value.

  Further, the usefulness of the member who is the content creation registrant may not be converged in the same manner, so this is also recalculated.

  In this way, by recalculating the importance of the content added / deleted as a bookmark and the usefulness of the member who created and registered the content, and repeating the recalculation until they converge, the importance and usefulness This calculation can be performed efficiently in a short time without impairing reliability.

In addition, by providing a recalculation flag as one item of member additional information and content additional information, importance and usefulness can be recalculated with certainty.

  This embodiment is another embodiment when sorting the content search results in descending order of the importance of the content and displaying them on the client terminal 2 as described in the previous embodiment.

  When the search results of content are sorted and displayed in descending order of the importance of the content, the content that has not been bookmarked by any member has an importance of 0, and the sort using the importance is reflected Not. In this case, the content that has just been created and registered will remain at the bottom of the search results indefinitely, regardless of the quality of the content, and will not be visible to members searching for the content.

  Therefore, this embodiment is characterized in that the search result display means 23 sorts the search results in consideration of the usefulness of the member who created and registered the content. Even if the content is not bookmarked, the content created and registered by a highly useful member is more important, and the search results useful for the member who searched the content by sorting in the order of the member's usefulness Can be given.

  Specifically, description will be made below based on the flowchart of FIG. The flowchart in FIG. 9 is an alternative to S250 in FIG. 6.
