Description

  The present invention relates to a technique for providing a portal page in which portlets are arranged.

  One of services on the web (World Wide Web) is called a portal system. The portal system provides a web page as an entrance / entrance for a user to access content on the web. In many portal systems, one or more portlets can be arranged on such a web page. A portlet is a detachable user interface component placed on a web page. Hereinafter, a web page on which such a portlet is arranged is referred to as a portal page.

  In recent years, such portlets have frequently used client processing such as JavaScript (registered trademark) in order to improve the operability of GUI (Graphical User Interface) and emphasize design. The portal server transmits a portal page generated by combining a plurality of such portlets to the client device. Then, the client device executes client processing included in each portlet of the received portal page, and displays each portlet on the portal page.

  At this time, if a portlet that uses a lot of client processing is arranged on the portal page, it takes time for the client processing of the portlet, and there is a problem that the display performance of the portal page in the client device is deteriorated.

  As a technology related to the display performance of such a portal page, there is one that displays an alternative portlet on a portal page for a portlet whose response waiting time in a client device exceeds a threshold (see, for example, Patent Document 1). In this related technology, for each portlet placed on the portal page, the response waiting time in the client device of the portlet is recorded. This related technology replaces the portlets placed on the portal page of each user whose response waiting time exceeds the threshold with other portlets belonging to the same category as the portlet with the shortest response waiting time. .

  In addition, as another technology related to the display performance of such a portal page, there is one that observes information indicating the popularity of a portlet and generates a portal page that preferentially synthesizes a portlet with a high popularity (for example, , See Patent Document 2). This related technique observes the number of connections established between a server that provides portlet content and a portal server that provides a portal page, for example, as the popularity of portlets arranged on the portal page. In this related technique, the portlet having the number of connections equal to or less than the threshold is regarded as low in popularity, and the composition process for including the portlet in the portal page is omitted.

  However, the device described in Patent Document 1 records the time from the request start time of the portlet from the client device to the time when the client device receives the portlet as the response waiting time. Therefore, this related technology does not consider the time required for client processing after the client device receives the portlet. For this reason, in this related technology, when a terminal with low hardware performance, such as a smartphone or a mobile phone, accesses a portal page including a portlet that frequently uses client processing, there is a problem that hardware resources for client processing are insufficient. Arise. As a result, there arises a problem that the display time of the entire portal page becomes slower than expected on the side of providing the portal system.

  In addition, what is described in Patent Document 2 observes the number of connections established between a server that provides portlet content and a portal server that provides a portal page as popularity. Therefore, this related technology also does not consider the time required for portlet client processing. For this reason, also in this related technology, when a terminal with low hardware performance as described above accesses a portal page including a portlet that frequently uses client processing, the display performance of the entire portal page is degraded.

  The display setting information acquisition unit 18 acquires the display setting information of each portlet included in the portal page generated by the portal page generation unit 17 from the display setting information storage unit 14.

  The portal page response transmission unit 19 sends a portal page response including the portal page generated by the portal page generation unit 17 and the display setting information of each portlet acquired by the display setting information acquisition unit 18 to the client device. Send.

  The operation of the portal server 10 configured as described above will be described with reference to FIG.

  Here, first, the portal page request receiving unit 15 receives a portal page request from the client device (step S1). As described above, the portal page request includes information requesting the portal page and display time history information of each portlet included in the portal page.

  Next, the display setting information updating unit 16 displays the display time of the portlet stored in the display time condition storage unit 13 with the display time indicated by the display time history information of each portlet included in the portal page request received in step S1. It is verified whether or not the time condition is satisfied (step S2).

  If it is determined that the display time condition is satisfied, the display setting information update unit 16 updates the display setting information of the portlet stored in the display setting information storage unit 14 to indicate that the portlet is to be displayed in a simplified manner (step S3).

  On the other hand, if it is determined that the display time condition is not satisfied, the display setting information update unit 16 updates the display setting information of the portlet stored in the display setting information storage unit 14 to indicate that the portlet is normally displayed (step) S4).

  Next, the portal page generation unit 17 refers to the portal page definition information storage unit 12 to obtain a list of portlet IDs indicated by the portal page definition information related to the portal page that is the target of the portal page request (step S5). ). At this time, if the layout information is included in the portal page definition information, the portal page generation unit 17 also acquires the layout information.

  Next, the portal page generation unit 17 acquires the display content information of each portlet indicated by the list acquired in step S5 by requesting the portlet storage unit 11 (step S6).

  Next, the portal page generation unit 17 generates a portal page including display content information of each portlet (step S7). If the layout information of each portlet has been acquired in step S5, the portal page generation unit 17 may generate a portal page in which the display content information of each portlet is arranged according to the layout information.

  Next, the display setting information acquisition unit 18 acquires the display setting information of each portlet included in the portal page generated in step S7 from the display setting information storage unit 14 (step S8).

  Next, the portal page response transmission unit 19 transmits a portal page response including the portal page generated in step S7 and the display setting information of each portlet acquired in step S8 to the client device (step). S9).

  Thus, the portal server 10 ends the operation. The display branching process and the display time measurement process in the portal page included in the portal page response transmitted in step S9 are executed by the client device when the portal page is displayed. As a result, the client device simply displays the portlet whose display setting information included in the portal page response indicates the simplified display, and normally displays the portlet whose display setting information indicates the normal display. Furthermore, the client device measures the display time of each normally displayed portlet, updates the display time history information, and includes the updated display time history information in the next portal page request.

  An example of the portal page A displayed on the client device A by the portal server 10 operating as described above is shown in FIG. In FIG. 8, portlet C is minimized in accordance with an example of the display setting information shown in FIG.

  Next, effects of the first exemplary embodiment of the present invention will be described.

  The portal server as the first embodiment of the present invention can provide a portal page on which a portlet including client processing is arranged without lowering its display performance even to a client device having low performance. it can.

  The reason is that the display time condition storage unit stores the display time condition with respect to the display time in the client device of the portlet placed on the portal page, and the portal page request reception unit, together with the request for the portal page from the client device, Display time history information indicating the past display time of each portlet of the portal page is received, and the display setting information update unit is based on whether or not the display time indicated by the received display time history information satisfies the display time condition. This is because the display setting information indicating whether the portlet is displayed simply or normally on the client device is updated. In addition, the portlet storage unit outputs the display content information of the portlet including the display time measurement process and the display branch process, and the portal page generation unit displays the portal page on which the display content information of each portlet including these client processes is arranged. This is because the generated portal page is transmitted to the client device together with the display setting information of each portlet.

  Thus, the client device executes the display branching process and the display time measurement process when displaying the portal page transmitted together with the display setting information. Therefore, the client device simply displays a portlet indicating that the display setting information is simply displayed. Such a portlet is determined to satisfy the display time condition in the past display time in the client device. Therefore, the client device can simply display a portlet that has taken a long time for display processing in the past. As a result, the portal server as an embodiment of the present invention can prevent a decrease in portal page display performance in the client device.

  Further, let us consider a case where the portlet display content information includes client processing for improving operability and design in addition to the above-described display branch processing and display time measurement processing. In such a case, such a portlet is likely to have a long display time in a low-performance client device. The client device stores the display time history information of such a portlet by executing the display time measurement process, and transmits it together with the next portal page request. Therefore, the portal server as the present embodiment can update the display setting information of the portlet to the simplified display when the portal page request is next received from the client device. Then, the portal server as the present embodiment transmits display setting information indicating that such a portlet is simply displayed together with the requested portal page to the client device. As a result, the client apparatus can simply display a portlet that has a heavy display process due to the client process for improving the operability and the design.

The display time measurement process in this embodiment calculates a statistical value related to the display time for each portlet, counts the cumulative number of times each portlet has been displayed in the client device 30 in the past, and displays the display time. This is client processing in which the statistical value and the cumulative display count are included in the display time history information and stored in the client device 30.

  The display setting information update unit 26 determines whether or not the cumulative number of displays indicated by the display time history information included in the portal page request received from the client device 30 satisfies a predetermined condition. Then, for the portlet whose accumulated display count satisfies the predetermined condition, the display setting is verified by verifying the display time indicated by the display time history information in the same manner as the display setting information updating unit 16 in the first embodiment of the present invention. The information storage unit 14 is updated.

  Next, each functional block of the client device 30 will be described.

  The display time history information storage unit 31 stores display time history information for each portlet included in the portal page. For example, the display time history information includes a statistical value of display time when the corresponding portlet has been displayed in the past, and the cumulative display count of each portlet. The statistical value of the display time may be, for example, an average value of past display times.

  For example, an example of the display time history information stored in the display time history information storage unit 31 is shown in FIG. The display time history information in FIG. 11 indicates that, for example, the cumulative display count of the portlet A included in the portal page A in the client device 30 is 3 times, and the average display time so far is 4 seconds. .

  The portal page request transmission unit 32 transmits a portal page request to the portal server 20. At this time, the portal page request transmission unit 32 receives the portal page request in response to the portal page request, and the display time history information stored in the display time history information storage unit 31 for each portlet included in the portal page. To include.

  The portal page response receiving unit 33 receives a portal page response from the portal server 20. The portal page response includes a portal page including display content information of each portlet and display setting information regarding each portlet.

  The display setting information extraction unit 34 extracts display setting information regarding each portlet from the portal page response received by the portal page response reception unit 33.

  The client process execution unit 35 executes various client processes included in the portal page response received by the portal page response reception unit 33. These various client processes are included in the display content information of each portlet included in the portal page response.

  Specifically, the client process execution unit 35 refers to the display setting information extracted by the display setting information extraction unit 34 to execute a display branch process for each portlet included in the portal page. As a result, the client process execution unit 35 simply displays a portlet indicating that the display setting information is simply displayed, and normally displays a portlet indicating that the display setting information is normally displayed.

  In addition, the client process execution unit 35 executes a display time measurement process for each portlet included in the portal page. Thereby, the client process execution unit 35 measures the display time required for the display process of the portlet that is normally displayed. And the client process execution part 35 calculates the statistical value of the display time measured in the past including the measured display time. For example, the client process execution unit 35 acquires the statistical value of the past display time stored in the display time history information storage unit 31, and uses the acquired statistical value and the display time measured this time to create a new statistic. A value may be calculated. The statistical value may be an average value. In addition, the client process execution unit 35 counts the cumulative display count of the corresponding portlet. For example, the client process execution unit 35 may acquire the display cumulative number of times of the corresponding portlet from the display time history information storage unit 31 and set a value obtained by adding 1 to the acquired display cumulative number as the new display cumulative number. Then, the client process execution unit 35 causes the display time history information storage unit 31 to store the display time history information of each portlet including the new statistical value of the display time and the new display cumulative count.

  In addition, if the display content information of the portlet that is normally displayed includes other client processes, the client process execution unit 35 also executes the client process.

  The portal page display unit 36 displays a portal page including each portlet subjected to display branch processing by the client process execution unit 35.

  The operation of the portal system 2 configured as described above will be described with reference to FIG.

  Next, the display setting information update unit 26 performs display setting information update processing based on the display time history information of each portlet included in the portal page request received in step S13 (step S15). Details of this step will be described later.

  In addition, the process of step S14 and step S15 is random.

  Next, the display setting information acquisition unit 18 acquires the display setting information of each portlet included in the portal page generated in step S14 from the display setting information storage unit 14 (step S16).

  Next, the portal page response transmission unit 19 transmits a portal page response including the portal page generated in step S14 and the display setting information of each portlet acquired in step S16 to the client device 30 (step S17). ).

  Next, the portal page response receiving unit 33 of the client device 30 receives the portal page response (step S18).

  Next, the display setting information extraction unit 34 extracts display setting information of each portlet included in the portal page response received in step S18 (step S19).

  Next, the client process execution unit 35 executes a simplified display or normal display process for each portlet in the portal page included in the portal page response received in step S18 based on the display setting information extracted in step S19. (Step S20). Details of this step will be described later.

  Next, the portal page display unit 36 aggregates the display content information of each portlet generated by the client process execution unit 35 into one and displays it as a portal page (step S21).

  Thus, the portal system 2 ends the operation.

  Next, the portal page generation operation in step S14 will be described with reference to FIG.

  Here, first, the portal page generation unit 17 acquires a list of portlet IDs and layout information arranged on the requested portal page from the portal page definition information storage unit 12 (step S31).

  Next, the portal page generation part 17 performs step S32-S33 about each portlet which the acquired list shows.

  Here, the portal page generation part 17 requests | requires the display content information of this portlet first from the portlet storage part 21 (step S32).

  Next, the portlet storage unit 21 outputs display content information of the requested portlet and returns it to the portal page generation unit 17 (step S33). For example, the portlet storage unit 21 may output the corresponding display content information by executing a computer program stored for the requested portlet. The display content information includes various client processes including at least a display branch process and a display time measurement process.

  Next, the portal page generating unit 17 generates a portal page in which the display content information of each portlet obtained by executing steps S32 to S33 for each portlet is arranged according to the layout information acquired in step S31 ( Step S34).

  This is the end of the description of the portal page generation operation in step S14.

  Next, the display setting information update operation in step S15 will be described with reference to FIG.

  Here, first, the display setting information update unit 26 acquires display time history information of each portlet included in the portal page request received in step S13 (step S41).

  Next, the display setting information update unit 26 performs the following processes of steps S42 to S47 for each portlet.

  Here, first, the display setting information updating unit 26 extracts the cumulative number of displays included in the display time history information (step S42).

  Next, the display setting information updating unit 26 determines whether or not the cumulative display count of this portlet satisfies a predetermined condition (step S43). For example, the display setting information update unit 26 may determine whether or not the cumulative display count of this portlet has exceeded a threshold value.

  Here, when it is determined that the display cumulative number satisfies the predetermined condition, the display setting information updating unit 26 extracts the display time statistic value from the display time history information acquired in step S41 (step S44).

  Next, the display setting information updating unit 26 determines whether or not the statistical value of the portlet display time satisfies the portlet display time condition stored in the display time condition storage unit 13 (step S45). For example, the display setting information updating unit 26 may determine whether or not the average value of the display time exceeds a display time threshold determined for the portlet.

  Here, when it is determined that the display time statistic satisfies the display time condition, the display setting information update unit 26 updates the display setting information of the portlet to indicate that the display is simplified (step S46).

  On the other hand, when it is determined that the display time statistic value does not satisfy the display time condition, the display setting information update unit 26 updates the display setting information of the portlet to indicate normal display (step S47).

  In step S43, when the display accumulation count does not satisfy the predetermined condition, the display setting information update unit 26 repeats the processing from step S42 for the next portlet.

  This is the end of the description of the display setting information update operation in step S15.

  Next, the display processing operation of each portlet in step S20 will be described with reference to FIG.

  In FIG. 15, the client process execution unit 35 performs the following steps S51 to S58 for each portlet.

  First, the client process execution unit 35 determines whether the display setting information extracted by the display setting information extraction unit 34 in step S19 represents simple display or normal display for this portlet (step S51).

  Here, when the display setting information represents a simplified display, the client process execution unit 35 generates information representing a simplified display area by hiding at least a part of the display content of the portlet (step S52). For example, the client process execution unit 35 may generate information representing a display area in which the portlet is minimized.

  On the other hand, when the display setting information indicates normal display, the client process execution unit 35 starts measuring the display time of the portlet (step S53).

  Next, the client process execution unit 35 generates information representing a display area representing the display content of the portlet in a normal display format (step S54). For example, the client process execution unit 35 may generate information that displays the display content of the portlet in an area of a predetermined size. At this time, the client process execution unit 35 also executes the client process if the display content information of the portlet includes another client process.

  Next, the client process execution unit 35 ends the measurement of the display time of the portlet (step S55).

  Next, the client process execution unit 35 calculates a new statistical value for the display time of this portlet (step S56). Here, the client process execution unit 35 refers to the display time measured in step S55 and the statistical value of the past display time of this portlet stored in the display time history information storage unit 31 for the calculation process. To do so.

  Next, the client process execution unit 35 counts the cumulative display count of this portlet (step S57). Here, the client process execution unit 35 may execute the count process by referring to the past display cumulative number of the portlet stored in the display time history information storage unit 31.

  Next, the client process execution unit 35 displays the display time history information including the new statistical value of the display time calculated in step S56 and the new display cumulative count counted in step S57, as the display time history information storage unit 31. (Step S58).

  This is the end of the description of the display processing operation for each portlet in step S20.
