It is a figure explaining the flow of a process until it determines a life event from a user's usage history, and produces | generates a menu in the case where a user terminal is PC. It is a figure explaining the flow of the process which updates service DB.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a configuration of a concierge apparatus that provides a concierge service on an Internet portal. User 2 accesses each service via a concierge device on the portal. A concierge device 10 shown in FIG. 1 includes an access history collection unit 11, an access history DB (access history database) 12, a life event estimation unit 13, a life event DB (life event database) 14, and a service presentation / collection unit. 15 and a service DB (service database) 16. The concierge device 10 can be configured as a computer, and a program describing processing contents for realizing each function of the concierge device 10 is stored in a storage unit of the computer, and a central processing unit (CPU) of the computer is stored. This can be realized by reading and executing this program. Note that the access history DB 12, the life event DB 14, and the service DB 16 may be provided outside the concierge device 10 instead of inside.

The access history collection unit 11 is connected to the web pages of the service providers 3 _{1 to} 3 _N , and collects the access history of the user 2 to the web page. In the access history DB 12, the access history collected by the access history collection unit 11 is recorded for each user. For the access history, the user 2 uses a different type of user terminal such as a personal computer (PC), a mobile phone terminal, an Internet-compatible TV, an Internet-compatible street terminal, etc., with different communication means and communication paths. Access history when accessing the page is included. When collecting the access history, pre-registration from the user 2 is not particularly required.
Further, the access history collection unit 11 refers to the access history DB 12 and extracts keywords from the collected access history.

  In the life event DB 14, keywords and life events (marriage, retirement, illness, etc.) are associated and recorded in advance. The life event estimation unit 13 searches the life event DB 14, extracts the life event associated with the keyword extracted by the access history collection unit 11 from the life event DB 14, and the life event that the user is currently encountering (Marriage, retirement, illness, etc.) Since the life event is estimated only from the access history, no prior registration or the like by the user 2 is required.

In the service DB 16, life events and services are associated and recorded in advance. The service presentation / collection unit 15 searches the service DB 16, extracts a service associated with the life event estimated by the life event estimation unit 13 from the service DB 16, and links and procedures to the service on the portal screen. Present. In addition, the service presentation / collection unit 15 is connected to the 4 ₁ to 4 _N web pages of the local governments that provide the service and the web pages of other public services 5.

  In addition, the concierge device 10 stores user attribute information 17 in a storage unit (not shown), and the service presentation / collection unit 15 uses the user attribute information 17 to create a local government related to the user 2 or the like. Collect links from web pages to services related to life events. The user attribute information 17 is information such as the residence, age, and sex of the user 2 and is assumed to be included in the identity confirmation information at the start of the service. Pre-registration by the user 2 other than the attribute information is not particularly required.

  When a user accesses a Web page, the user goes through a concierge device that constructs the portal 1. This makes it possible to determine which Web page has been accessed even for different types of user terminals with different communication means and communication paths. For example, it is possible to collect access histories not only from a personal computer (PC) but also from a mobile phone terminal or an Internet-compatible television. Although a service for converting the format of a Web page for a PC to a mobile phone is provided, it is assumed that the concierge device 10 is incorporated into an extension of such a service for a plurality of access means. ing.

FIG. 2 is a diagram for explaining the flow of processing from when a user terminal is a mobile phone terminal until a life event is determined from the user's usage history and a menu is generated. Here, it is assumed that the identity of the user has been confirmed.
When a portal screen providing a concierge service is displayed on a mobile phone terminal (user terminal), and a user 2 inputs a URL from the mobile phone terminal on the portal screen (S101) and accesses the Web (S102), The access history collection unit 11 of the concierge device 10 records the accessed URL and time in the access history DB 12 for each user (S103), and is provided by the service providers 3 _{1 to} 3 _N with the URL input by the user 2 The web page to be accessed is accessed (S104). Upon obtaining the access result from the service provider (S105), the access history collection unit 11 of the concierge device 10 records the content and time of the access result in the access history DB 12 (S106), and shapes the access result according to the terminal type and carries it. It is displayed on the portal screen of the telephone terminal (S107). The user 2 browses the access result displayed on the screen of the mobile phone terminal (S108).

  The access history collection unit 11 of the concierge device 10 is recorded in the access history DB 12 after the above operation is repeated to complete the access of the user 2 or in parallel behind the access of the user 2. Then, the full text search is performed on the content of the Web page accessed by the user 2 with a long stay time (viewing time), and a keyword having a high appearance frequency is extracted (S109). The keyword extraction function such as the existing Japanese full-text search system is used for keyword extraction. The appearance frequency is calculated for the extracted keyword.

  When calculating the appearance frequency, synonyms are also counted. The access history collection unit 11 passes keywords having a high appearance frequency to the life event estimation unit 13. As a method for determining a keyword to be transferred depending on the magnitude of appearance frequency, a method of adding keywords from the top to occupy 60% of the whole, a method of using keywords from the top of appearance frequency to the middle value, an average value of appearance frequency One of the methods for calculating and calculating a keyword equal to or higher than the average value is adopted.

The content of the Web page as a keyword extraction target is made different for each type of user terminal in consideration of the characteristics of the user terminal. In the case of mobile phone terminals and TVs, the amount of information that can be displayed at one time is limited due to restrictions on screen size, screen resolution, and operation means, and information that users are seeking is included in pages with long viewing times. Focusing on the fact that there is a high probability that the page has transitioned, the page transition time is recorded, prioritized according to the length of stay time within the range of a series of operations, and then a Web page with a high priority (for example, , The top three, etc.) are to be extracted. By eliminating Web pages with a short stay time, the processing time can be shortened, and an irrelevant page that has transitioned due to an erroneous operation can be excluded from the target, and an effect of improving the accuracy in life event estimation described later can be expected.
In addition, in mobile phone terminals, there are cases where notices not related to the contents of the text and page operations such as “next” and “previous” are inserted in the first and last lines, so the first and last lines Lines including links before and after the first line and the first line are omitted from the extraction target.

  When the life event estimation unit 13 receives a keyword from the access history collection unit 11, the life event estimation unit 13 searches the life event DB 14 based on the received keyword, extracts a life event containing many matching keywords including synonyms, The life event is estimated as the life event that the user is currently encountering (S110). For example, if the keyword is “baby” or “milk”, the life event estimation unit 13 estimates “childcare” as the life event. In the life event DB 14, in order to identify a life event from a keyword, a keyword related to each life event is recorded in advance. The life event estimation unit 13 passes the estimated life event information to the service presentation / collection unit 15.

When the service presentation / collection unit 15 receives the life event information from the life event estimation unit 13, the service presentation / collection unit 15 searches the service DB 16 based on the received life event information, and local governments related to the life event information 4 ₁ to 4. Administrative services provided by _N are extracted (S111). Then, the service presentation / collection unit 15 generates a user presentation menu for the next access including the extracted service information for each user (reflects the search result) (S112). For example, if the life event is “childcare”, the service presentation / collection unit 15 searches for “childcare allowance” or the like as the service information, and adds a link and a procedure to the service such as “childcare allowance” to the portal screen. .
The above processing is performed after the user's access is completed (when no access is made for a certain period of time) or periodically (immediately after updating the service DB described later).

FIG. 3 is a diagram for explaining the flow of processing from when a user terminal is a PC until a life event is determined from a user's usage history and a menu is generated. Here, it is assumed that the identity of the user has been confirmed. The only difference from the case of FIG. 2 is the keyword extraction target, and the rest is the same as in FIG.
When the user 2 inputs the URL from the PC on the portal screen (S201) and accesses the Web (S202), the access history collection unit 11 of the concierge device 10 accesses the access URL and time for each user. The data is recorded in the DB 12 (S203), and the Web page provided by the service providers 3 _{1 to} 3 _N is accessed using the URL input by the user 2 (S204). When the access history collection unit 11 of the concierge device 10 obtains the access result from the service provider (S205), the content and time of the access result are recorded in the access history DB 12 (S206), and the access result is shaped according to the terminal type and carried. It is displayed on the portal screen of the telephone terminal (S207). The user 2 browses the access result displayed on the PC screen (S208).

  The access history collection unit 11 of the concierge device 10 is recorded in the access history DB 12 after the above operation is repeated to complete the access of the user 2 or in parallel behind the access of the user 2. Then, a full text search is performed for a paragraph including a link to a Web page with a long stay time (viewing time) accessed by the user 2, and a keyword having a high appearance frequency is extracted (S209).

  In the case of a PC, since a large amount of information is displayed on one page, extra information is included. Therefore, in order to eliminate this, a paragraph (blank line) including a link to a Web page accessed by the user is included. A keyword having a high appearance frequency is extracted with a segmented range as a paragraph). Note that a paragraph including a link and paragraphs before and after the link may be extracted. In this way, the present invention improves the accuracy of life event estimation, which will be described later, by making the extraction target when extracting keywords different for each type of user terminal in consideration of the characteristics of the user terminal. ing.

  Furthermore, as in the case of a mobile phone terminal, the time at the time of transition is recorded, prioritized according to the length of the stay time after the transition, and then a web page with a high priority (for example, the top three) Etc.) are included in the extraction target. By eliminating paragraphs that contain links to web pages with short stays, the processing time will be shortened, and paragraphs that contain links to pages that have no relationship due to misoperation will be excluded from the life events described below It can also be expected to improve the accuracy of estimation.

When the life event estimation unit 13 receives a keyword from the access history collection unit 11, the life event estimation unit 13 searches the life event DB 14 based on the received keyword, extracts a life event containing many matching keywords including synonyms, The life event is estimated as the life event that the user is currently encountering (S210). When the service presentation / collection unit 15 receives the life event information from the life event estimation unit 13, the service presentation / collection unit 15 searches the service DB 16 based on the received life event information, and local governments related to the life event information 4 ₁ to 4. Administrative services provided by _N are extracted (S211). Then, the service presentation / collection unit 15 generates a user presentation menu for the next access including the extracted service information for each user (reflects the search result) (S212).

FIG. 4 is a diagram for explaining the flow of processing for updating the service DB. The local governments 4 ₁ to 4 _N advertise the new administrative service on the Web page provided by the local governments (S301). The service presentation / collection unit 15 of the concierge device 10 uses the user attribute information 17 to select a local government where the user lives or works, and periodically accesses the local government web page ( S302) The presence or absence of a new administrative service is checked from the posting date, new arrival display, etc., and new arrival information is acquired (S303). Then, the contents of newly arrived information are searched in full text, and keywords with high appearance frequency are extracted (S304). For extraction of keywords from new arrival information and calculation of appearance frequency, the same method as in the case of extraction of keywords from user access history and calculation of appearance frequency described in FIG. 2 is used.
Next, the service presentation / collection unit 15 searches the life event DB 14 based on the extracted keywords having a high appearance frequency, extracts life events including many synonyms and matching keywords (S305), The service information is recorded in the service DB 16 using as a key to update the service DB 16 (S306).
