Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information retrieval system, an information retrieval method, and a recording medium capable of accurately retrieving desired information from information published on a huge number of Web sites on the Internet.

[0002]

2. Description of the Related Art In recent years, with the development of computer networks and the like, users can use their own terminals to obtain desired information from distant computers. In particular, the spread of the Internet (higher usage)
This allows users to obtain information from various computers around the world. A user using the Internet generally uses a predetermined Web browser to open a huge Web on the WWW (World Wide Web).
URL (Uniform Resource Locator) from the home page (Web page) published on the site
Browse the specified homepage.

[0003] Recently, a Web site called a search engine capable of searching for a desired homepage from a huge number of homepages is also known. In general, this search engine searches a database or the like that stores homepage information that is an outline of the homepage of each website provided by the user according to a search keyword input by a user, and specifies a target homepage. Then, list information including the specified title of the homepage and the URL of the Web site is generated, and the generated list information is displayed. The user can easily browse the homepage by selecting a desired homepage from the displayed information list.

[0004]

However, since such a search engine simply searches for an input search keyword as a character string, the search intended by the user may not be accurately performed.

[0005] For example, when a user resident in Nagasaki Prefecture wants to browse a homepage about a hotel in the prefecture, simply use a conventional search engine and simply search for “hotel”.
A large number of list information including hotels irrelevant to Nagasaki will be displayed even if the search is performed using "" as a search keyword. Further, even if a search is performed by adding "Nagasaki" to the search keyword, a list of hotels including a place name other than Nagasaki Prefecture or "Nagasaki" used as a mere unique name is displayed. The same applies to a case where a user residing in Osaka Prefecture searches a homepage for a hotel in Nagasaki Prefecture, which is considered as a travel destination. That is, the conventional search engine has a drawback that it cannot accurately search for information on a specific area desired by the user.

The present invention has been made in view of the above situation, and provides an information retrieval system capable of accurately retrieving desired information relating to a specific area from information published on a huge Web site on the Internet.

Hereinafter, information search processing in the information search system according to the third embodiment will be described with reference to FIG. FIG. 11 is a flowchart for explaining the information search process. The information search process shown in FIG. 11 is performed by the user terminal 1 to the search server 23 in a state where the excluded area index table in which the user name, the area code and the address information are associated with each other in the excluded area DB 233 in advance. On the other hand, it starts when the search request information is sent.

First, the exclusion area management unit 232 acquires search request information including the user name sent from the user terminal 1 (step S31). That is, the excluded area management unit 2
32 acquires search request information including a user name as shown in FIG. 12A via the communication processing unit 31.

The exclusion area management unit 232 searches the exclusion area DB 233 according to the search request information, and obtains exclusion area information including an area code and address information corresponding to the user name (step S32). That is, the excluded area management unit 232 acquires the excluded area information as shown in FIG. 12B from the excluded area index table stored in the excluded area DB 233.

The excluded area management unit 232 supplies the obtained excluded area information and the search keyword included in the search request information to the information collection control unit 34 (step S33).

The information collection control unit 34 searches the Web site 2 using the obtained search keyword and the excluded area information (step S34). That is, the information collection control unit 34 includes a search keyword, for example, “Chinatown” from each Web site 2 and excludes area information, for example,
An HTML file not including “045 Yokohama City” is specified, and the URL and title information of the HTML file are acquired.

The information collection control unit 34 generates list information including the title information and the like acquired from the Web site 2 and the URL (step S35). That is, the information collection control unit 34 generates list information that does not include “Chinatown in Yokohama” as shown in FIG.

The information collection control unit 34 transmits the generated list information to the user terminal 1 (Step S36). That is, the information collection control unit 34, via the communication processing unit 31,
The URL of the home page that includes the search keyword specified by the user and does not include the exclusion area information registered in advance by the user and the list information including the title information of the home page are transmitted to the user terminal 1. User terminal 1
Receives the list information sent from the search server 23 and displays it on a predetermined display or the like. The user terminal 1 acquires a URL designated by the user from the list information, connects to the Web site 2 specified by the acquired URL, and displays a desired homepage.

As a result, a huge Web on the Internet
From the information published on the site b, desired information on a specific area can be accurately searched.

In the third embodiment, the information collection control unit 34 directly searches each Web site 2 by using a search keyword or the like. However, the information collection control unit 34 has home page information which is an outline of the Web site in each Web site 2 in advance. In advance, the homepage information may be searched.

The information retrieval system according to the embodiment of the present invention can be realized by using a general computer system without using a dedicated system. For example, a medium (floppy disk, CD-ROM) storing a program for executing any of the above in a computer
By installing the program from
An information search system that performs the above-described processing can be configured.

The medium for supplying the program to the computer may be a communication medium (medium for temporarily and fluidly storing the program, such as a communication line, a communication network, or a communication system). For example, the program may be posted on a bulletin board (BBS) of a communication network and distributed via the network. Then, by starting this program and executing it in the same manner as other application programs under the control of the OS, the above-described processing can be executed.

As described above, according to the present invention,
From information published on a huge number of Web sites on the Internet, desired information on a specific area can be searched accurately.
