  The association management unit 117 acquires other portlets related to the portlet included in the portal screen requested to be displayed from the screen portlet relationship table 103, and sets a query restriction corresponding to the acquired other portlets. It is acquired from the relevance master table 104.

  The query generation unit 118 generates an acquisition condition that integrates the document information acquisition condition of the portlet and the document information acquisition conditions of other portlets related to the portlet. Further, when a query restriction is acquired from the relevance master table 104 by the relevancy management unit 117, an acquisition condition in which the acquired query restriction is added to the generated acquisition condition is further generated.

  The document management server connection unit 119 transmits / receives document information to / from the document management server 400. The document management server connection unit 119 is used when the screen processing unit 113 acquires information to be displayed on the portlet.

  The document management server 400 manages document information using a document table 401 and a document attribute management table 402. The document table 401 is a table that stores document information itself, and is a table in which document IDs that uniquely identify document information are associated with document information.

  The document attribute management table 402 is a table for storing attributes of document information, and is referred to by the portlet processing unit 115 when a condition for acquiring the attribute is specified in the document information acquisition condition.

  FIG. 7 is an explanatory diagram showing an example of the data structure of the document attribute management table 402. As shown in the figure, the document attribute management table 402 represents the document ID, the document title, the file name, the creator, the updater, the document classification indicating the document type, and the name of the related project. The project name, creation date, update date, and abstract are stored in association with each other.

  Note that the document information storage method is not limited to the table format as described above, and the document information may be stored in an XML format including the document information and attributes.

  Next, a configuration example of the information portal screen will be described. FIG. 8 is an explanatory diagram illustrating an example of an information portal screen displayed in the first embodiment.

  In this embodiment, since it is assumed that a portal screen is mainly created for each project, the information portal screen 801 includes a plurality of portlets for displaying information related to a certain project (project A). The figure shows an example in which two document management portlets for displaying document information acquired from the document management server 400 and other portlets for displaying information acquired from the business application server 500 are displayed. Has been.

  FIG. 9 is an explanatory diagram for explaining an example of the configuration of the information portal screen displayed in the first embodiment. As shown in the figure, the information portal screen 901 can include a plurality of document management portlets 911, 912, 913, and 914. Each document management portlet corresponds to the document management server 400 from which the document information is acquired. As in the document management portlets 911 and 912, document information may be acquired from the same document management server 400b.

  Next, information providing processing by the document portal management apparatus 100 according to the first embodiment configured as described above will be described. FIG. 10 is a sequence diagram illustrating an overall flow of the information providing process in the first embodiment.

  First, a portal screen request including the portal screen ID of the portal screen to be displayed is transmitted from the client PC 200 to the document portal management apparatus 100 (step S1001). The portal screen request is transmitted to the screen management unit 112 via the transmission / reception unit 111 (step S1002).

  The screen management unit 112 acquires screen information of the portal screen corresponding to the portal screen ID included in the received portal screen request from the screen management table 101, and transmits the screen information to the transmission / reception unit 111 (step S1003).

  Next, the transmission / reception unit 111 transmits a portal screen information request for requesting specific information to be displayed in the portal screen to the screen processing unit 113 (step S1004). The portal screen information request mainly requests acquisition of information in which information to be displayed on each portlet is embedded in portal screen information of the screen management table 101. Accordingly, the screen processing unit 113 receives the received portal screen information request, acquires information to be displayed on each portlet, and generates and returns portal screen information. Details of this processing will be described below.

  First, the screen processing unit 113 transmits a portlet information request for requesting information about each portlet in the portal screen to the portlet management unit 114 (step S1005). The portlet information request includes a portlet ID.

  Next, the portlet management unit 114 acquires the portlet information corresponding to the portlet ID included in the portlet information request from the portlet management table 102 and transmits it to the screen processing unit 113 (step S1006).

  Next, the screen processing unit 113 refers to the document information acquisition condition included in the portlet information, and issues a portlet screen information request, which is a request for acquiring specific information (portlet screen information) to be displayed on the portlet. The data is transmitted to the processing unit 115 (step S1007).

  Next, the portlet processing unit 115 executes portlet screen information generation processing for generating portlet screen information in conjunction with the portlet management unit 114, the relationship management unit 117, the query generation unit 118, and the document management server connection unit 119. (Step S1008). Details of the portlet screen information generation process will be described later.

  Next, the portlet processing unit 115 transmits the generated portlet screen information to the screen processing unit 113 (step S1009). Subsequently, the screen processing unit 113 determines whether all portlets included in the portal screen have been processed (step S1010).

  If all the portlets have not been processed (step S1010: NO), the screen processing unit 113 transmits a portlet information request for the next portlet and repeats the processing (step S1005).

  When all the portlets have been processed (step S1010: YES), the screen processing unit 113 sends a business application information request, which is a request for acquiring information related to the business application, to the business application server 500 via the application connection unit 116. Transmit (step S1011, step S1012).

  Note that the processing in steps S1011 and S1012 is executed only when a dedicated portlet for displaying information such as business processing results by the business application server 500 is present in the displayed portal screen.

  The business application server 500 executes business processing according to the request and transmits the business application information as a result to the application connection unit 116 (step S1013). In addition, the application connection unit 116 transmits the received business application information to the screen processing unit 113 (step S1014).

  Next, the screen processing unit 113 generates portal screen information in which the portlet screen information of each portlet and business application information are embedded (step S1015). Subsequently, the screen processing unit 113 transmits the generated portal screen information to the client PC 200 via the transmission / reception unit 111 (steps S1016 and S1017).

  The client PC 200 displays the portal screen on a display unit such as a WEB browser in accordance with the received portal screen information (step S1018).

  Next, details of the portlet screen information generation processing in step S1008 will be described. FIG. 11 is a sequence diagram showing the overall flow of the portlet screen information generation process.

  First, the portlet processing unit 115 transmits an acquisition request for a document information acquisition condition for a portlet to the portlet management unit 114 (step S1101). The acquisition request includes the portlet ID. The portlet management unit 114 acquires the document information acquisition condition corresponding to the portlet ID included in the received acquisition request from the portlet management table 102 and transmits it to the portlet processing unit 115 (step S1102).

  Next, the portlet processing unit 115 transmits a list of portlets related to the portlet to be displayed and a request for acquiring the relationship type to the relationship management unit 117 (step S1103). The acquisition request includes the portlet ID of the portlet to be displayed.

  Next, the relationship management unit 117 acquires the portal screen, portlet, and relationship type corresponding to the portlet ID included in the received acquisition request from the screen portlet relationship table 103 (step S1104). The reason why not only the corresponding portlet but also the corresponding portal screen is acquired is to further acquire the portlets and the like included in the acquired portal screen.

  Specifically, the relevancy management unit 117 displays the To type, ToID, and relevance type of the relevance information that matches the portlet type and the portlet ID included in the acquisition request received from the ID. From the sex table 103. Based on the acquired To type, it is possible to determine whether the related object (related object) is a portal screen or a portlet.

  Next, when the association target acquired in step S1104 is a portal screen, the association management unit 117 further acquires a list of portlets related to the portal screen from the association table 103 (step S1105). As described above, this embodiment can be configured to link associations between three or more portlets or portal screens. Also in this case, a condition obtained by combining the document information acquisition conditions of three or more related portlets can be generated, so that more appropriate information can be easily displayed.

  Next, the association management unit 117 transmits the acquired list of portlets and the association type to the portlet processing unit 115 (step S1106). Next, the portlet processing unit 115 transmits a corresponding query restriction acquisition request to the relationship management unit 117 for each received relationship type (step S1107). The acquisition request includes a relevance type ID.

  Next, the relationship management unit 117 acquires the query restriction corresponding to the relationship type ID included in the received acquisition request from the screen portlet relationship table 103, and transmits it to the portlet processing unit 115 (step S1108).

  Next, the portlet processing unit 115 transmits a document information acquisition condition acquisition request for each portlet included in the portlet list received in step S1106 to the portlet management unit 114 (step S1109). The acquisition request includes a portlet ID.

  The portlet management unit 114 acquires the document information acquisition condition corresponding to the portlet ID included in the received acquisition request from the portlet management table 102, and transmits the acquired document information acquisition condition to the portlet processing unit 115 (step S1110).

  Next, the portlet processing unit 115 obtains the document information acquisition condition for the portlet to be displayed received in step S1102, the document information acquisition condition for the related portlet received in step S1110, and the query restriction received in step S1108. It transmits to 118 (step S1111).

  Next, the query generation unit 118 generates a query condition from the document information acquisition condition of the portlet to be displayed (step S1112). The query condition is generated using a query language such as SQL (Structured Query Language) or XQuery (XML Query) according to the document management server 400 of the reference destination.

  Next, the query generation unit 118 integrates the document information acquisition conditions of the related portlets with the generated query conditions (step S1113). For example, the document information acquisition condition is “reference destination = search module document portlet, refinement condition = reference refinement condition / document of the last month, acquisition item = document title / updater / update date, number of acquisitions = 5, sort Assume that the condition is specified as “condition = descending date”. In this case, the query generation unit 118 replaces the “reference target narrowing condition” portion in the narrowing condition with the narrowing condition specified in the document information acquisition condition of the “search module document portlet” that is the related portlet. To do.

  Next, the query generation unit 118 adds a query restriction to the query condition (step S1114). For example, when “document title, only disclosure of update date” corresponding to the related information (relevance type ID = 5) in FIG. 6 is transmitted as a query restriction, “document title / update” is acquired as an acquisition item in the document information acquisition condition. Even if “updater / update date” is specified, the query condition is changed so that “updater” is not acquired.

  In this way, the acquisition conditions can be changed in consideration of not only the document information acquisition conditions for the reference destination portlet but also the relevance information with the reference destination portlet. Appropriate information can be displayed. In addition, this makes it possible to control the display contents according to the user, so that access right management for each user on the document management server 400 requiring complicated work is not required. There is an advantage that you can.

  Next, the query generation unit 118 transmits the generated query condition to the portlet processing unit 115 (step S1115). The portlet processing unit 115 transmits a document information acquisition request including the received query condition to the document management server 400 via the document management server connection unit 119 (steps S1116 and S1117).

  The document management server 400 retrieves necessary information from the document table 401 and the document attribute management table 402 according to the query condition included in the received document information acquisition request, and sends the document information as a retrieval result to the document management server connection unit 119. Transmit (step S1118). Further, the document management server connection unit 119 transmits the received document information to the portlet processing unit 115 (step S1119).

  The document management server 400 manages access rights for each user, and the portlet processing unit 115 determines whether or not the received document information display authority is satisfied according to the user access rights acquired from the document management server 400. The document information may be displayed only when it is determined and the authority is satisfied. Thereby, it is possible to display appropriate information according to the access right of the user.

  Next, the portlet processing unit 115 determines whether all portlets have been processed (step S1120). If all portlets have not been processed (step S1120: NO), document information about the next portlet The acquisition request for the acquisition condition is transmitted and the process is repeated (step S1109).

  If all portlets have been processed (step S1120: YES), the portlet processing unit 115 generates portlet screen information in which the acquired document information is embedded (step S1121), and ends the portlet screen information generation process.

  Next, an example of association between a portal screen and a portlet will be described. FIG. 12 is a conceptual diagram for explaining an example of association between a portal screen and a portlet.

  As shown in the figure, the document portal management apparatus 100 manages a plurality of information portal screens, and each information portal screen includes one or more portlets. An information portal screen that does not include a portlet may be associated.

  As types of portlets, there are a document management portlet for acquiring and displaying document information from the document management server 400, a portlet for acquiring and displaying information such as business processing results from the business application server 500, and the like. . Note that the types of portlets are not limited to this, and any conventionally used portlet can be included in the division portal screen.

  In the figure, solid arrows represent associations between portlets, between information portal screens, or between portlets and information portal screens. The types of association are as described above. In the same figure, screen transitions, related information, and related projects are shown as examples of association.

  Next, another example of association between a portal screen and a portlet will be described. FIG. 13 is an explanatory diagram showing an example of association between two information portal screens.

  The figure shows an example in which an information portal screen 1302 corresponding to project B, which is a related project of project A, is associated with the information portal screen 1301 corresponding to project A as the relationship type “related project”. ing.

  The information portal screen 1301 includes portlets 1303 and 1304 as document management portlets, and among these, the portlet 1304 is set with document information acquisition conditions so as to display information about the project B.

  On the other hand, the information portal screen 1302 includes portlets 1305 and 1306 as document management portlets. Of these, the portlet 1305 corresponds to the portlet 1304 in the information portal screen 1301.

  That is, in the portlet 1304, document information acquisition conditions are set such that the project name 1311 of the project B and the date 1312 and the title 1313 from the portlet 1305 displaying the conflict information of the project B are displayed.

  In this way, even when similar information is displayed on multiple information portal screens, there is no need to execute processing such as pasting links to information on individual portal screens as in the past. If the information is changed, the information displayed on the reference source portlet can be dynamically changed at the same time.

  Next, a specific example of document information acquisition condition integration processing will be described. FIG. 14 is an explanatory diagram showing an example of document information acquisition condition integration.

  In the figure, an example is shown in which an information portal screen 1402 of a related project is associated with an information portal screen 1401 and a relevance type 1422 is associated as “related project”.

  The information portal screen 1401 includes portlets 1403 and 1404 as document management portlets. Among these, the portlet 1404 has document information acquisition conditions set so as to display information of search module document portlets in the related project. . In the figure, for convenience of explanation, the document information acquisition conditions are described in a tabular format in the portlet. However, the actual portal screen does not display the document information acquisition conditions in this way. The acquired document information is displayed.

  On the other hand, the information portal screen 1402 includes portlets 1405 and 1406 as document management portlets, and the portlet 1405 corresponds to a search module document portlet corresponding to the portlet 1404 in the information portal screen 1401. The portlet 1406 is associated with the portlet 1403 in the information portal screen 1401.

  The portlet 1404 includes “reference destination = search module document portlet, filtering condition = reference filtering condition / document of the last month, acquisition item = document title / updater / update date, number of acquisitions = 5, sorting condition = date. The document information acquisition condition “descending order” is set.

  The reference destination 1411 (search module document portlet) can specify that the reference destination portlet is the portlet 1405. Further, since the refinement condition includes reference information 1412 (reference condition refinement condition) indicating that another portlet condition is referred to, the acquisition condition is integrated by embedding the other portlet condition in the reference information 1412 portion. It becomes possible to generate the query condition 1421.

  Furthermore, a document information acquisition condition for acquiring an item not included in the acquisition item of the reference portlet, such as a part 1413 (updater, update date) of the acquisition item, can be set. In this case, document information is acquired according to the set document information acquisition condition as long as the query restriction 1423 corresponding to the relevance type 1422 (document title, updater, update date, only abstract is disclosed) is satisfied.

  Similarly, in the portlet 1406, the reference destination 1414 can specify that the reference destination portlet is the portlet 1403. In addition, since the refinement condition includes reference information 1415 indicating that a condition of another portlet is referred to, a query condition in which the acquisition condition is integrated is generated by embedding the condition of the other portlet in the reference information 1415 portion. It becomes possible.

  Next, a specific example of association between a portal screen and a portlet will be described. FIG. 15 is an explanatory diagram showing a specific example of association between a portal screen and a portlet.

  This figure shows a specific example of the association between the six information portal screens and the portlets included in each information portal screen. Note that a part of the relevance information representing the association in the figure corresponds to the example of the relevance information shown in the screen portlet relevance table 103 in FIG. Further, the SID in the figure means a portal screen ID, and the PID means a portlet ID.

  As shown in the figure, a portal system that creates an information portal screen for each project and displays related project information such as a list of related projects and a list of usage documents in the portlets in each information portal screen. In addition, the document portal management apparatus 100 according to the present embodiment can be applied.

  As described above, in the document portal management apparatus 100 according to the first embodiment, when the portlet information in the other portal screen is displayed on the portlet in the portal screen, the portlet in the other portal screen is acquired. Information can be acquired with the acquisition conditions incorporating the conditions. Further, at that time, it is possible to add a restriction according to the relevance between other portal screens or portlets in other portal screens.

  Accordingly, it is possible to provide an information portal system that can easily display appropriate information including related information according to a project, a project, a purpose of use, and the like. In addition, it is not necessary to paste a related document on each information portal screen, and it is possible to present related information dynamically. Further, even when the access right is not given on the document management server side, it is possible to control information to be appropriately disclosed by restrictions according to acquisition conditions and relevance.

(Second Embodiment)
When the user newly creates an information portal screen or when a predetermined portlet is associated with another portal screen, the information providing apparatus according to the second embodiment is connected to the related existing portal screen. Relevance information is determined and saved in the screen portlet relevance table.

  In the second embodiment, the screen management unit 112 performs processing for determining relevance information between a newly created portal screen and an existing portal screen, and the portlet management unit 114 performs predetermined portlet or A screen portlet relevance table is used to perform processing for determining relevance information between a portal screen including a predetermined portlet and the portal screen, and the relevancy information determined by the relevance management unit 117 by the screen management unit 112 The point stored in 103 is different from the first embodiment.

  Other configurations and functions are the same as those in FIG. 1 which is a block diagram showing the configuration of the document portal management apparatus 100 according to the first embodiment, and a description thereof will be omitted here. The screen management unit 112 and the portlet management unit 114 correspond to the determination unit of the present invention.

  Next, relevance information registration processing by the document portal management apparatus 100 according to the second embodiment configured as described above will be described. FIG. 16 is a sequence diagram illustrating an overall flow of the relevance information registration process according to the second embodiment.

  First, login information including a user ID, a password, and the like input by the user is transmitted from the client PC 200 to the authentication / directory service 301 via the transmission / reception unit 111 (steps S1601 and S1602).

  The authentication / directory service 301 performs authentication processing with reference to the received login information, and transmits authentication information including a user ID, a user name, an authentication result, and the like to the transmission / reception unit 111 (step S1603). Further, the transmission / reception unit 111 transmits the authentication information to the client PC 200 (step S1604).

  Next, a new information portal screen creation instruction input by the user on the client PC 200 is transmitted to the screen management unit 112 via the transmission / reception unit 111 (steps S1605 and S1606). The creation instruction includes information to be stored in the screen management table 101 such as portal screen ID, creator, creation date, etc., in addition to portal screen information defining the display content of the created portal screen.

  Next, the screen management unit 112 acquires creator information from the authentication information (step S1607). Specifically, the screen management unit 112 acquires authentication information received by the transmission / reception unit 111, and acquires a user name included in the acquired authentication information as creator information.

  Next, the screen management unit 112 acquires a portal screen created by the same creator as the creator obtained in step S1607 from the screen management table 101 (step S1608). Subsequently, the screen management unit 112 sets the relevance information “same creator” between the acquired portal screen and the newly created portal screen (step S1609). It is assumed that the relevance information “same creator” is registered in the relevancy master table 104 in advance and appropriate query restrictions are set.

  Next, the screen management unit 112 transmits the set relevance information to the relevance management unit 117 (step S1610). The relevancy management unit 117 registers the received relevance information in the screen portlet relevance table 103 and transmits the registration result to the screen management unit 112 (step S1611).

  The above is an example in which the relevance information is determined and registered based on the information of the user who created the portal screen, but the relevance information determination method is not limited to this. For example, the relevance information may be determined based on the main department of the created portal screen. Below, the sequence of the process which determines relevance information based on a supervisory department is demonstrated.

  First, the main department of the information portal screen created by the user on the client PC 200 is input, and the input information is transmitted to the screen management unit 112 via the transmission / reception unit 111 (steps S1612 and S1613).

  Next, the screen management unit 112 acquires a portal screen associated with the same supervisory department as the received supervisory department from the screen management table 101 (step S1614). Subsequently, the screen management unit 112 sets the relevance information “same supervisory department” between the acquired portal screen and the newly created portal screen (step S1615). It is assumed that the relevance information “same supervisory department” is registered in advance in the relevance master table 104 and appropriate query restrictions are set.

  Next, the screen management unit 112 transmits the set relevance information to the relevance management unit 117 (step S1616). The relevancy management unit 117 registers the received relevance information in the screen portlet relevance table 103 and transmits the registration result to the screen management unit 112 (step S1617).

  Next, another example (modification) of the relevance information registration process will be described. In this modification, when another portal screen is associated with a predetermined portlet, the portal screen including the portlet is associated with another associated portal screen. FIG. 17 is a sequence diagram illustrating an overall flow of the relevance information registration process in the modification of the second embodiment.

  First, information on another portal screen (SID = 2) is added to a predetermined portlet (PID = 1) on a certain portal screen (SID = 1) input by the user on the client PC 200. The instruction is transmitted to the portlet management unit 114 via the transmission / reception unit 111 (steps S1701 and S1702).

  Next, the portlet management unit 114 adds information on the portal screen with SID = 2 to the portlet with PID = 1 in accordance with the received instruction (step S1703). For example, the above processing is executed when information for transitioning to a portal screen corresponding to a certain project is added to a portlet displaying a “related project list”.

  Next, the portlet management unit 114 sets relevance information “screen transition” between the portlet with PID = 1 and the portal screen with SID = 2 (step S1704). Note that the relevance information to be set is not limited to “screen transition”, and any relevance information corresponding to a predetermined portlet can be set.

  Next, the portlet management unit 114 transmits the set relevance information to the relevance management unit 117 (step S1705). The relevance management unit 117 registers the received relevance information in the screen portlet relevance table 103 and transmits the registration result to the portlet management unit 114 (step S1706).

  Next, the portlet management unit 114 transmits a portal screen acquisition request including a portlet with PID = 1 to the relevancy management unit 117 (step S1707). In response to the received acquisition request, the association management unit 117 acquires a portal screen including a portlet with PID = 1 from the screen portlet relationship table 103, and transmits the acquired portal screen to the portlet management unit 114 (step S1708). ).

  Next, the portlet management unit 114 sets the relationship information “related project” between the acquired portal screen and the portal screen with SID = 2 (step S1709).

  Next, the portlet management unit 114 transmits the set relevance information to the relevance management unit 117 (step S1710). The relevance management unit 117 registers the received relevance information in the screen portlet relevance table 103 and transmits the registration result to the portlet management unit 114 (step S1711).

  As described above, in this modification, when a predetermined portlet is associated with another portal screen, not only the relationship information is set between the portlet and the other portal screen (step S1704), Relevance information can be set between all portal screens including portlets and other portal screens (step S1709).

  As the predetermined portlet, as described above, a “related project list” portlet that displays a list of related projects, a “subproject list” portlet that displays a list of related subprojects, and the like can be specified.

  As described above, in the information providing apparatus according to the second embodiment, when a user newly creates an information portal screen or when a predetermined portlet is associated with another portal screen, a related existing Information related to the portal screen can be determined and stored in the screen portlet relationship table. For this reason, it is possible to easily set association, and when displaying the created portal screen, it is possible to obtain appropriate information with reference to the determined relevance information.
