The service server 2 and the integrated service server 3 and the information input / output terminal 4 are connected to each other via a network 5. A user of this system can access one or more service servers 2. Further, it is assumed that the administrator can access all the service servers 2 and can register information on the user (user information), change the user information, and the like with respect to the service server 2.

  The service server 2 stores user information and shared information posted by the user in the shared information providing system 1. Details will be described later with reference to FIG.

  The integrated service server 3 integrates and aggregates user information and shared information stored in a plurality of service servers 2 and performs processing for the entire shared information. Details will be described later with reference to FIG.

  The information input / output terminal 4 allows a user using the shared information providing system 1 to access the service server 2 to post shared information, and to access the service server 2 or the integrated service server 3 for sharing. Information can be browsed. Details will be described later with reference to FIG. In the following description, when the information input / output terminal 4 accesses (logs in) the service server 2 or the integrated service server 3, the user accesses the service server 2 or the integrated service server 3 by operating the information input / output terminal 4 (login). ) Means to do.

[Service Server]
FIG. 2 is a block diagram showing a configuration of the service server 2. The service server 2 includes a service server control unit 21, a user information storage unit 22, and a shared associated information storage unit 23. The service server control unit 21 includes an information input unit 211, a user authentication unit 212, a user information generation unit 213, a shared accompanying information generation unit 214, a keyword extraction unit 215, and a shared information output unit 216.

  When there is an access from the information input / output terminal 4, the information input unit 211 outputs login information (authentication information such as a user name, user ID number, access information, and password) to the user authentication unit 212, and the user who is permitted access When the user information is input (posted) from the information input / output terminal 4, the input user information is output to the user information generation unit 213, and the shared information is input from the information input / output terminal 4 by the authorized user. Then, the input shared information is output to the shared accompanying information generation unit 214 and the keyword extraction unit 215, and when the shared information browsing request is input from the information input / output terminal 4 by the user who is permitted to access, the input sharing information The information browsing request is output to the shared information output unit 216. Here, the user information is information including a user name, a real name (full name), a user ID number, authentication information such as a password, and the organization to which the user who is a user of the service server 2 belongs. User information is set by an administrator, for example.

  The user information generation unit 213 generates user information for each user based on the data input from the information input unit 211 and stores the user information in the user information storage unit 22.

  The user information storage unit 22 stores a user information table including user information input from the user information generation unit 213. FIG. 3 shows an example of a user information table stored in the user information storage unit 22.

  When there is an access from the information input / output terminal 4, the user authentication unit 212 compares the user information input from the information input unit 211 with the user information stored in the user information storage unit 22, and performs user authentication. If it does, access is allowed. If they do not match, access is denied.

  When the user inputs the shared information, the user also gives a title of the shared information, a user to be browsed for the shared information, a keyword of the shared information, and the like. For each piece of shared information, the shared incidental information generation unit 214 performs the shared information identifier (for example, ID number), the creator of the shared information, and the creation time of the shared information for each piece of information input from the information input unit 211. The shared incidental information to which the information is added is generated and output to the shared incidental information storage unit 23.

And a related accumulated information output unit 317.

  When there is an access from the information input / output terminal 4, the information input unit 311 outputs access information (authentication information such as a user name, user ID number, access information and password) to the user authentication unit 312, and the user who is permitted to access When the user information is input from the information input / output terminal 4, the input user information is output to the user integrated information generation unit 313, and the related shared information is output from the information input / output terminal 4 by the service server 2 or the user permitted to access. When the browsing request is input, the input related shared information browsing request is output to the related accumulated information output unit 317. Here, the related shared information refers to shared information associated with a common keyword described later.

  Further, the information input unit 311 has a function of accessing each service server 2 using the user name of a user (administrator) who can access all the service servers 2. Only the designated service server 2 may be accessible. The information input unit 311 accesses the service server 2, acquires user information stored in the user information storage unit 22, and outputs the acquired user information to the user integrated information generation unit 313. In addition, the information input unit 311 accesses the service server 2 to acquire the shared incidental information stored in the shared incidental information storage unit 23 and outputs the acquired shared incidental information to the shared incidental integrated information generation unit 314.

  The user integrated information generation unit 313 acquires the user information accumulated in the user information storage unit 22 from each service server 2 via the information input unit 311 and integrates the acquired user information to obtain the user integrated information. It is generated and output to the user integrated information storage unit 32. Here, the user name, real name, and user ID number are common to each service server 2, but the authentication information and the organization to which the user belongs can vary depending on the service server 2 and the integrated service server 3 that can be used by each user. Therefore, the authentication information and the belonging organization are associated with each service server 2 and integrated service server 3.

  The user integrated information storage unit 32 stores a user integrated information table including user integrated information input from the user integrated information generating unit 313. FIG. 6 shows an example of a user information integration table stored in the user integrated information storage unit 32. The user integrated information storage unit 32 also stores administrator user information.

  When accessed from the information input / output terminal 4, the user authentication unit 312 compares the user information input from the information input unit 311 with the user integrated information stored in the user integrated information storage unit 32 to authenticate the user. If they match, access is permitted, and if they do not match, access is denied.

  The shared accompanying integrated information generation unit 314 acquires the shared accompanying information (excluding shared information) accumulated in the shared accompanying information storage unit 23 from each service server 2 via the information input unit 311, and uses the shared accompanying information as the shared accompanying information. Then, the shared associated integrated information in which the name (for example, URL) of the service server that stores the shared associated information is associated is generated and output to the shared associated integrated information storage unit 33.

  The shared associated integrated information storage unit 33 stores a shared associated integrated information table including shared associated integrated information input from the shared associated integrated information generation unit 314. FIG. 7 shows an example of the shared associated integrated information table.

  The synonym search unit 315 acquires a keyword in the shared associated integrated information table accumulated in the shared associated integrated information storage unit 33, searches for a synonym of the keyword, and outputs it to the keyword classification information generating unit 316. The synonym search unit 315 searches a synonym by accessing a synonym search server (not shown). For example, a synonym dictionary site (for example, http://thesaurus.weblio.jp/) published on the Internet is accessed to search for synonyms.

  The keyword classification information generation unit 316 acquires the keywords in the shared associated integrated information table stored in the shared associated integrated information storage unit 33 and the synonyms of the keywords searched by the synonym search unit 315, and is common to the keywords or the keyword synonyms. Extract words as common keywords. Then, the keyword classification information generation unit 316 associates the extracted common keyword with the keyword of the shared information having the common keyword, the name of the service server storing the shared information, and the ID number of the shared information. Classification information is generated and output to the keyword classification information storage unit 34.

  The keyword classification information storage unit 34 stores a keyword classification information table including keyword classification information input from the keyword classification information generation unit 316. FIG. 8 shows an example of the keyword classification information table stored in the keyword classification information storage unit 34. The common keyword “abcdef” in FIG. 8 conceptually indicates that it is a synonym for the keyword “abc”, a synonym for the keyword “def”, and a synonym for the keyword “bcf”.

  FIG. 9 is a flowchart showing the operation of common keyword extraction. The synonym search unit 315 searches for and lists synonyms for each keyword of each shared information ID number in the shared associated integrated information table (step S11). When the process of step S11 is completed for all pieces of shared information ID numbers, the keyword classification information generation unit 316 passes through all shared information ID numbers and all keywords appearing over a plurality of shared information ID numbers and their synonyms. Are extracted as common keywords (step S12). Then, the keyword classification information generation unit 316 generates keyword classification information by associating each common keyword extracted in step S12 with a keyword, a service server name storing the keyword, and a shared information ID number ( Step S13). Here, the operations in steps S11 to S13 can be activated by the user, or can be automatically activated at certain time intervals.

  The related accumulation information output unit 317 stores the related shared information browsing request designating the keyword from the information input / output terminal 4 or the service server 2 via the information input unit 311 and stores it in the keyword classification information storage unit 34. The common keyword associated with the designated keyword is selected with reference to the keyword classification information table, and the list information of the service server name and the shared information ID number associated with the common keyword is acquired. Subsequently, the related accumulated information output unit 317 refers to the shared associated integrated information table stored in the shared associated integrated information storage unit 33 and associates it with the service server name and the shared information ID number acquired from the keyword classification information table. Obtained browsing target user. Then, the related accumulated information output unit 317 refers to the user integrated information table stored in the user integrated information storage unit 32, and whether or not the user who requests browsing of the shared information corresponds to the browsing target user. If the service server name and the shared information ID number acquired from the keyword classification information table are extracted as the related accumulated information, it is determined. That is, the related storage information is information indicating in which service server 2 the related shared information that can be viewed is stored. The related stored information output unit 317 sends the related stored information to the service server 2 or the information input / output terminal 4.

[Information input / output terminal]
FIG. 10 is a block diagram showing a configuration of the information input / output terminal 4. The information input / output terminal 4 includes an information input unit 41, a display unit 42, and a control unit 43. The information input unit 41 receives input from the user and outputs the input information to the control unit 43. The control unit 43 performs processing according to information input by the user, and exchanges information with the service server 2 and the integrated service server 3 via the network 5. The control unit 43 controls the display unit 42 to display the shared information acquired from the service server 2 and the related accumulated information acquired from the integrated service server 3.

[System Operation]
Next, the operation of the shared information providing system 1 as a whole will be described. FIG. 11 is a flowchart showing an operation (initial setting and posting of shared information) in the shared information providing system 1. As an initial setting, the administrator sets user information for the service server 2 of each user in each service server 2, and sets user information for the integrated service server 3 in the integrated service server 3 (step S21). Each service server 2 uses the user information generation unit 213 to create the user information table shown in FIG. When the user information is added or changed, the administrator adds or changes it. For example, the affiliation information is changed by the administrator when the affiliation organization is changed. It is also possible to create a virtual belonging organization according to the user's request through the operation of the administrator.

  The integrated service server 3 accesses each service server 2 to acquire user information, and the user integrated information generation unit 313 creates the user information integrated table shown in FIG. 6 (step S22). This operation is automatically performed at regular intervals, or the administrator instructs the integrated service server 3 to perform this operation.

  In response to the request of the entire system, the integrated service server 3 limits the range of the service server 2 that aggregates the shared information as necessary (step S23). For example, it is limited to implementation on an intranet. Thereby, the accuracy of the shared user information and the shared information related to the user can be improved.

  The user operates the information input / output terminal 4, inputs a user name, a user ID number, and authentication information, and accesses (logs in) the service server 2 connected to the network 5 (step S24). After the access to the service server 2 is successful, the user posts shared information to the service server 2 through the information input / output unit 41 (step S25).

  When the user inputs the shared information, the user also gives a title of the shared information, a user to be browsed for the shared information, a keyword of the shared information, and the like. In addition to the keyword being given by the user, the keyword extraction unit 215 can extract the keyword from the input shared information. In addition, the browsing target user (publication range) may be specified by a user name or by an organization to which the user belongs.

  The shared information providing system 1 also includes the shared information stored in the other service server 2 regarding the shared information to be input and the keywords of the information to be browsed when the user performs the operation of step S25. The feature is that it can be browsed. Specific operations for providing shared information are shown below.

[First operation example of system]
FIG. 12 is a flowchart illustrating a first operation example of providing shared information in the shared information providing system 1. The integrated service server 3 generates shared associated integrated information by the shared associated integrated information generation unit 314 at regular intervals, searches for synonyms of keywords in the shared information by the synonym search unit 315, and shares the common information by the keyword classification information generation unit 316. Keywords are extracted to generate keyword classification information (step S101). The user operates the information input unit 41 to access (log in) the service server 2-a and post shared information (step S102). Alternatively, a browsing request for shared information is made by designating a keyword or a title (step S104). In order to distinguish between the plurality of service servers 2, the code of the service server accessed by the user in steps S102 and 103 is denoted as 2-a, and the sign of other service servers described later is denoted as 2-b.

  When the shared information is posted in step S102, the service server 2-a causes the shared accompanying information generation unit 214 to share the shared information, the shared information identifier (for example, ID number), and the shared information for each shared information to be posted. Sharing-related information including the viewing target user and the keyword of the sharing information is generated. Further, the service server 2-a performs a morphological analysis process on the shared information posted in step S102 by the keyword extraction unit 215, and extracts keywords (step S103).

  The service server 2-a provides corresponding shared information in response to the shared information browsing request in step S104 (step S105).

  When the user designates a keyword and makes a sharing information browsing request in step S104, the service server 2-a makes a request for browsing the related shared information by designating the keyword to the integrated service server 3. This is performed (step S106). In addition, when the user designates a title and requests viewing of the shared information in step S104, the service server 2-a refers to the shared incidental information table stored in the shared incidental information storage unit 23, and the user The keyword associated with the title designated by is acquired, and the relevant shared information is requested to be browsed by designating the keyword (step S106). Note that the common keyword extraction processing by the keyword classification information generation unit 316 may be performed immediately before the keyword classification information extraction processing in step S108 described below (step S107).

  Next, the related accumulated information extraction process in step S108 will be described.
