The portal timeline generating device 1 of the present invention generates a Web page (portal timeline page (see FIG. 6)) that displays posting information of a predetermined Web page in a timeline format. Here, the timeline-format Web page in the present embodiment refers to a Web page that automatically notifies posting information of a certain Web page (a predetermined Web page) along the time axis. Specifically, as will be described later with reference to FIG. 6, when a new information is posted on a certain Web page, it refers to a Web page that automatically notifies the posted information (that is, regardless of a user instruction). In this embodiment, as a certain Web page (predetermined Web page), a top page of a portal site with a high update frequency (see FIG. 11) is taken as an example, and notification is automatically made on the portal timeline page. As post information, description will be made with reference to table of contents information (table of contents information 101 to 104, personal information 107, 108, etc. in FIG. 11) displayed on the top page and set to a detailed page.
Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[First Embodiment]
First, the portal timeline generating device 1 according to the first embodiment will be described with reference to FIGS.

[Functional configuration of portal timeline generating device 1]
With reference to FIG. 1, the functional configuration of the portal timeline generating device 1 of the present invention will be described.

  The portal timeline generating device 1 of the present invention is communicably connected to a web server 2 that manages a predetermined web page (top page of a portal site) and a user terminal 3 that browses the portal timeline page, and acquires data. A unit 11 and a timeline page generation unit 12 are configured.

[Data acquisition unit 11]
Since the data acquisition unit 11 acquires post information from the top page of the portal site managed by the Web server 2, the Web page acquisition unit 111, the post information acquisition unit 112, the post information analysis unit 113, and the post information transmission unit 114, a page log database 115, and a posting information database 116.

The web page acquisition unit 111 accesses the top page of the portal site managed by the web server 2 at a predetermined timing and acquires the data (HTML data) of the top page. The timing at which the Web page acquisition unit 111 accesses the Web page can be arbitrarily set, but the access timing may be determined based on the scheduled update interval of the Web page as will be described later.
When the Web page acquisition unit 111 acquires Web page data, the Web page acquisition unit 111 stores the data in the page log database 115 in association with the acquired time.

  Here, the page log database 115 will be described with reference to FIG. The page log database 115 stores the Web page data (HTML data) acquired by the Web page acquisition unit 111 in association with the time when the data is acquired.

The posted information acquiring unit 112 acquires posted information newly posted on the Web page from the data acquired by the Web page acquiring unit 111. That is, the posting information acquisition unit 112 refers to the data of the Web page stored in the page log database 115, and more specifically, the posting information acquisition unit 112 detects a difference in data for each time, thereby newly posting on the Web page. Get posted information.
When the posted information acquisition unit 112 acquires posted information newly posted on the Web page, the posted information acquisition unit 112 stores the posted information in the posted information database 116 in association with the acquired time.

The posted information analyzing unit 113 analyzes the category of the posted information for each posted information acquired by the posted information acquiring unit 112.
Here, referring to the portal top page 100 of FIG. 11, a large amount of table of contents information is displayed on the portal top page 100. In FIG. 11, the portal top page 100 displays table of contents information 101 indicating earthquake early warning, table of contents information 102 indicating sports news, table of contents information 103 indicating economic news, and table of contents information 104 indicating weather forecast. ing. As an example, the posting information analysis unit 113 analyzes the tag information of the portal top page 100 and analyzes the category of the posting information from the ID information attached to the table of contents information 101 to 104. For example, for the table of contents information 101 indicating earthquake bulletin, the category is analyzed from the ID information “emergency bulletin” attached to the tag information, and for the table of contents information 102 indicating sports news, the ID information “news” attached to the tag information. (Sports) "category analysis.

Here, in the portal timeline page generated by the portal timeline generation device 1 of the present invention, newly posted information is automatically notified, so depending on the update frequency of the Web page, the user may soon know. New post information may be notified one after another on the portal timeline page. Therefore, in the portal timeline generating device 1 of the present invention, post information is notified again at a predetermined interval.
The posting information analysis unit 113 analyzes the re-notification interval (transmission interval) for each posting information. Specifically, a re-notification interval (transmission interval) is determined in advance for each category, and the posting information analysis unit 113 specifies a predetermined transmission interval for each analyzed category.
The transmission interval for each category can be set arbitrarily. For example, for highly urgent information such as earthquake early warning, the transmission interval is set short and the frequency of updating is low as in the weather forecast. For information with low urgency, the transmission interval can be set long.

By the way, if posting information posted in the past was re-notified for many hours, the posting information notified on the portal timeline page will increase. It is preferable to increase the re-notification interval.
Therefore, the posted information analyzing unit 113 analyzes the elapsed time (staleness) after posting, and updates the transmission interval of the posted information having a longer elapsed time.
At this time, the transmission interval updated for a long time can be arbitrarily set. For example, the change in the length of the transmission interval (drop of the transmission interval) may be made different for each category. By the way, for post information such as weather forecast, the drop in the need for information in time units is small (depending on the content, it is required during the day), but for post information such as breaking information, There is a large drop in the need for information in time units (for example, the baseball bulletin “1st bulletin” is no longer necessary when the “4th bulletin” is posted). Therefore, the posted information analysis unit 113 may vary the drop in the transmission interval for each category, more specifically, for each freshness of the posted information (scheduled update interval).

The posted information analyzing unit 113 analyzes the freshness (scheduled update interval) of such posted information for each posted information acquired by the posted information acquiring unit 112. Specifically, the freshness (scheduled update interval) is determined in advance for each category of the posted information, and the posted information analysis unit 113 analyzes the freshness (scheduled update interval) from the analyzed category.
For example, post information such as weather forecasts do not need to be updated frequently, so the freshness (scheduled update interval) may be set longer. For information that is in time (timely), the freshness (scheduled update interval) may be set short.

These pieces of information analyzed by the posted information analyzing unit 113 are stored in the posted information database 116 as appropriate.
Here, the post information database 116 will be described with reference to FIG. The posted information database 116 is associated with the posted information acquired by the posted information acquisition unit 112, and includes the category, freshness (scheduled update interval), staleness (elapsed time), transmission interval, link destination URL, and the like of the posted information. Various types of information are stored.
At this time, various types of information stored in the posted information database 116 are appropriately updated by analysis of the posted information analysis unit 113. As an example, the posting information “postponement of professional baseball” in the category “News (Sports)” and the posting information in the category “News (Economy)” “Measures to save electricity for companies” are freshness (scheduled update interval) Although the same, the transmission interval of the category “news (sports)” is set shorter. This is because the transmission interval of the posting information of the category “News (Economy)” has been updated longer due to the update of the transmission interval based on the degree of obsolescence (elapsed time).

Here, the predetermined timing when the Web page acquisition unit 111 accesses the Web page will be described with reference to the posting information database 116 of FIG.
As shown in FIG. 3, in the present embodiment, the freshness (scheduled update interval) is stored for each acquired post information. Therefore, the Web page acquisition unit 111 may access the Web page based on this freshness (scheduled update interval). Specifically, the Web page may be accessed at the interval of the shortest freshness (scheduled update interval) stored in the posted information database 116.
In FIG. 3, since the freshness (scheduled update interval) of the category “Emergency Early Warning” is the shortest, the Web page acquisition unit 111 accesses the Web page at this interval and acquires data.

In addition, when acquiring the Web page, the Web page acquisition unit 111 may acquire only the portion of the Web page where the posting information is described, instead of acquiring the entire Web page. The Web page acquisition unit 111 acquires data of only the portion in which the corresponding post information is described with the freshness (schedule update interval) for each post information. Note that the acquisition of data only for the portion where the posting information is described can be arbitrarily performed. For example, the position of the tag information is stored for each posting information or category, and the data is based on the position. Can be obtained.
In FIG. 3, the Web page acquisition unit 111 acquires data at intervals of 1 minute for the portion where the category “Emergency Bulletin” is described, and at intervals of 10 minutes for the portion where the category “News (Sports)” is described. Get the data.

  Returning to FIG. 1, each time the posting information acquisition unit 112 acquires new posting information, the posting information transmission unit 114 transmits the new posting information to the timeline page generation unit 12 and stores it in the posting information database 116. The corresponding posting information is retransmitted to the timeline page generation unit 12 at the transmitted interval.

[Timeline page generator 12]
In response to receiving the posted information from the posted information transmitting unit 114, the timeline page generating unit 12 generates a portal timeline page that displays the received posted information. In other words, the timeline page generation unit 12 newly adds the received posting information to the portal timeline page. At this time, when receiving post information, the timeline page generating unit 12 automatically generates a portal timeline page regardless of a user instruction. In addition, the link based on the link destination URL of FIG. 3 is set in the posted information to be added, and when the user selects, the transition from the portal timeline page to the detailed page is performed.
The portal timeline page generated by the timeline page generation unit 12 is transmitted to the user terminal 3 and viewed by the user of the user terminal 3.
