Description

  When a user of a mobile terminal device in an area searches for information related to the area using the mobile terminal device, the present invention searches for a search keyword useful for the user in the area. The present invention relates to an information search apparatus and an information search program that can be provided based on a result.

  In an information search service provided by a portal site on the Internet, when a user accesses the portal site using a terminal device such as a PC (personal computer) or a mobile phone, a keyword input field and a search are displayed on the display screen of the terminal device. A button is displayed. When the user inputs a keyword and clicks the search button, the search is executed by the search server on the portal site, and a list of hit information summaries (title, summary, etc.) is displayed on the display of the terminal device. When the user selects an arbitrary one from the list and clicks on the title etc., the information selected by the user is displayed on the display of the terminal device by jumping to the URL linked to the title etc. Is done.

  Here, in the portal site, when a keyword is entered in the keyword input field, a list of search candidate keywords including the keyword is displayed under the keyword input field, thereby assisting keyword input for narrowing down. There is something to do. That is, for example, when the area name “Shinjuku” is entered in the keyword input field, search candidate keywords including “Shinjuku” include “Shinjuku Gyoen”, “Shinjuku Station”, “Shinjuku Ward”, “Shinjuku Lunch”, “ Search candidate keywords such as “Shinjuku Hotel” are displayed. This search candidate keyword is obtained by collecting past search requests including the search keyword and search results for the search keyword into a database, and extracting a large number of keywords from the database. For example, when the user places a cursor on “Shinjuku lunch” and clicks, a restaurant that provides lunch in Shinjuku is searched, and the list is displayed on the display of the terminal device.

  However, the above search candidate keywords (“Shinjuku Gyoen”, “Shinjuku Station”, “Shinjuku Ward”, “Shinjuku Lunch”, “Shinjuku Hotel”, etc.) are based on the aggregation of search results that include “Shinjuku” in the keyword. Because it is not based on the aggregation of search results in response to search requests from people who were actually in “Shinjuku”, it is possible to know what kind of search was actually performed by people who were in “Shinjuku”. There is no problem. Also, if you do not know the search results of people who have been in "Shinjuku" in the past, and you search for the same reason as those who have been in "Shinjuku" in the past, you can easily search if you know the search results However, there are cases where useful search results cannot be obtained, or even if search results are obtained, it takes time, and search efficiency is poor.

  The present invention has been made to solve such a problem, and its purpose is to be in an area when a user of a mobile terminal device in a certain area searches for information using the mobile terminal device.

<Operation of information retrieval system>
The operation of the information search system having the above configuration will be described using the flowchart shown in FIG. The processing in this flowchart is performed by the CPU 211 executing a program stored in the ROM 212.

  First, the user of the mobile terminal device 4 performs an operation for starting an application for using the information search server 2. In response to this operation, the mobile terminal device 4 transmits a connection request signal to the information search server 2 (step S1). This connection request signal includes the mobile terminal device ID of the mobile terminal device 4.

  In the information search server 2, the communication unit 22 receives the connection request signal and sends it to the control unit 21. When the control unit 21 acquires the mobile terminal device ID in the connection request signal and stores it in the RAM 213 and confirms that the mobile terminal device ID exists in the user information DB 51, the control unit 21 asks the mobile terminal device 4 for search. The web page 20 is transmitted (step S11). At this time, user attribute information is read from the user information DB 51 and stored in the RAM 213.

  The mobile terminal device 4 receives and displays the search web page 20 (step S2). When the user performs a predetermined operation on the screen, the mobile terminal device 4 transmits the current position information acquired by the built-in GPS receiver to the information search server 2 (step S3).

  In the information search server 2, the communication unit 22 receives the current position information and sends it to the control unit 21. The control unit 21 acquires the portable terminal device ID and stores it in the RAM 213, performs statistical processing using the current position information, the attribute information previously stored in the RAM 213, and the clock information acquired from the clock, and searches history Keywords that are highly likely to be searched by the user of the mobile terminal device 4 are extracted from the information DB 52 and set as search candidate keywords (step S12).

  Here, the statistical processing is performed as follows, for example. First, in an area including the current position (for example, Shinjuku), a list is created by extracting a predetermined number of keywords searched in the past by a user registered in the user information DB 51 in descending order of the number of searches. Next, the list is reconfigured in consideration of user attribute information (age, gender, occupation, hobby, preference, etc.), clock information, and the characteristics of the mobile terminal device 4 to obtain a search candidate keyword list. For example, if the user of the mobile terminal device 4 is a 28-year-old office worker and it is 6 pm on Friday, the search keyword is izakaya or a restaurant, and the user of the mobile terminal device 4 is a 20-year-old female student. Yes, if it is 0:00 on Saturday, a bookstore, karaoke, cake shop, etc. can be considered as search candidate keywords.

  Next, the information search server 2 transmits the search candidate list to the mobile terminal device 4 (step S13). The mobile terminal device 4 receives this search candidate keyword list and displays it on the display unit (step S4). When the user of the mobile terminal device 4 selects one of the displayed search candidate keywords, the keyword is transmitted to the information search server 2 (step S5).

  When the information search server 2 receives the keyword, the information search server 2 stores the keyword in the search history information DB 52 and refers to the Web page information DB 53 to search for information related to the keyword (for example, if the keyword is a tavern, a list of nearby taverns). ) And the URL of the link destination are acquired and used as search result information and transmitted to the mobile terminal device 4 (step S14).

  The mobile terminal device 4 receives and displays the search result information (step S6). When the user selects any one of the displayed search result lists, the user is connected to the linked WWW server 3 of the mobile terminal device 4 and the browsing web page 30 is displayed.

  As described above, according to the information search system of the embodiment of the present invention, the totals of user search histories registered in the user information DB 51 are stored in the search history information DB for each area that was in the search. When a user of the mobile terminal device 4 performs a search, the search history at the current position is statistically processed using the attribute information of the user, the identification information of the mobile terminal device 4 and the clock information, thereby the user Can be displayed on the mobile terminal device 4 as a list of search candidate keywords.

  In FIG. 4, the mobile terminal device 4 transmits the current position information after receiving the search Web page from the information search server 2, but transmits it together with the mobile terminal device ID when a connection request is made to the information search server 2. You can also

  In FIG. 4, the mobile terminal device 4 directly accesses the information search server 2 and the information search server 2 searches the DB 5, but the mobile terminal device 4 accesses the information search server 2 via the WWW server 3. You may comprise.

  In FIG. 4, when the mobile terminal device ID in the connection request signal does not exist in the user information DB 51, the information search server 2 specifies the connection request date and time, and based on conditions such as day of the week, time, and location. In addition, an optimum keyword may be extracted from information stored in the search history information DB 52.

  Furthermore, in the above embodiment, the mobile terminal device 4 has a built-in GPS receiver, but the GPS receiver may be externally attached. Further, without using a GPS receiver, the current location can be specified from location registration information for a mobile phone base station or an IP address set when communication is performed.
