Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document search service providing method and apparatus, a document search service providing program, and a storage medium storing the document search service providing program. The present invention relates to a document search service providing method and apparatus for collecting a set of documents to be searched, a document search service providing program, and a storage medium storing the document search service providing program in a search system that searches for documents that match a condition.

[0002]

2. Description of the Related Art Conventionally, a method of creating a page called a link collection has been adopted in order to share information about which WWW site has what information among people who are interested in a particular topic. Has been. The link collection is as shown in Fig. 10. Using the hyperlink function of WWW,
Links to related WWW sites are placed, and the titles, logos, and brief introductions of the links are added. The user can judge which site has desired information by looking at this introduction.

However, in the conventional method using the link collection, it becomes difficult to find a desired site from the link collection as the number of related sites increases. Then, a directory-type search service represented by "Yahoo" was considered. This is a system for manually categorizing WWW sites and inputting explanations, and searching for WWW sites based on this. It can be said that a directory-type search service is, in a sense, a large collection of links that deal with all topics, with a search function added.

On the other hand, as a service for searching for an ever-increasing number of WWW pages, a search service called robot type search is also widely used. The robot-type search service automatically follows the WWW page links
It uses a program called "information gathering robot" or "crawler" that collects WW pages.
Since they collect information mechanically, they cannot provide categories or introductory sentences like link collections and directory-type search services, but they are new to WW.
W pages can be automatically discovered,
WWW that cannot be found by the directory-type search service because the WWW page itself is the search target
You can also find the page. Also, since the information collecting robot constantly updates the information, it is possible to perform a search based on the latest information.

While making use of such advantages of the robot type search service, it is also provided to provide a search service specialized only for a specific topic. This is a WWW site where robots travel around, and a WW related to a specific topic.
It is realized by limiting to W site only.

[0006]

However, in the above-described conventional link collections and directory search services, since updating is manually performed, information is apt to become old, and so-called link destinations no longer exist. It is easy for a situation such as a disconnection or the absence of new WWW site information. In particular, since the directory service targets the information at the time of data registration as a search target, it is often impossible to search by the recent keywords.

Further, in the robot type search service, although information is updated frequently, the search target cannot be limited to a specific topic, and a large number of WWW pages that are not needed by the user are included in the search results. Will be included. Moreover, since there is no additional information such as an introduction sentence and a category, it is difficult for the user to determine which link should be selected from the search results.

[0008] Further, in the method of limiting the WWW sites that the robot crawls to identify a topic, the function of discovering a new WWW site, which is a feature of the robot type search service, does not work, and information also becomes old. To do.

The present invention has been made in view of the above points, and makes it easy for people who are interested in a particular topic to share the latest WWW page information recommended by each person, and An object of the present invention is to provide a document search service providing method and apparatus for constructing a specialized WWW page search service, a document search service providing program, and a storage medium storing the document search service providing program.

Then, in addition to the page ID that distinguishes the page, it has a site ID indicating which WWW site the page is included in. The site ID is used for grouping at the time of search.

Next, the processing at the time of retrieval will be described.

FIG. 7 is a flowchart of the search operation according to the embodiment of the present invention.

Step 201) First, it is confirmed whether or not a search keyword is given to the access from the search user terminal 40. If no search keyword is given, the process proceeds to step 211.

Step 202) When a search keyword is given, the full-text search engine 162 is used to obtain a set of page IDs of WWW pages including the given search keyword.

Step 203) If there is a search result in Step 202, move to Step 204,
If not, the process proceeds to step 221.

Step 204) If there is a search result, each page ID is grouped by site ID using the WWW page DB 161.

Step 205) The score of the site is calculated for each site ID. This score may be the sum of the scores returned by the full-text search engine for each WWW page,
It may be simply how many WWW pages are hits included in the WWW site.

Step 206) The site information is sorted in descending order of the score obtained in Step 205.

Step 207) The search results are truncated to the maximum number that can be displayed on the search result screen. It is desirable to construct the number of WWW pages that can be displayed on one screen so that the number can be changed by setting.

Step 208) The display data concerning the WWW site and WWW page remaining in Step 207 is W
WW site information DB 151 and WWW page DB 161
To get from.

Step 209) Create a search result screen combining the display data obtained in Step 208,
Send to the search user terminal 40 and end.

Step 211) When the search keyword is not input in Step 201, the search screen is displayed. The search screen includes a text field for inputting a search keyword and a search button.

Step 221) If the search result is zero in Step 203, "the number of searches is 0".
Is displayed and the process ends.

FIG. 8 shows an example of the search result screen in the embodiment of the present invention. The search result is a title 203 for each WWW site, an introduction sentence 204 of the site input by the information registrant, a name (ID) 205 of the information registrant, and a title group 20 of WWW pages that have been successfully matched with the search keyword.
6 is displayed. Title 203 and title group 20
6 is a hyperlink. Click the title 203 to jump to the top page of the WWW site. In addition, the title group 206 is W that has hit the search.
Jump to the WW page itself. The information registrant ID 206 can also be a hyperlink to the information registrant's email address. In this way, since the search result of the device 10 is presented with an introduction sentence for each site, it is easy to understand which WWW page should be viewed.
In addition, since the information registrant name is presented, it is possible to provide a judgment material that it is certain that Mr. A's recommendation will be correct.

Next, the WWW page update process will be described.

FIG. 9 shows W in one embodiment of the present invention.
It is a flowchart of WW page information update.

The updating of the WWW page is started by the timer 13.

Step 301) First, when the process of the WWW page collection unit 14 is periodically activated from the timer 13 such as once a day, the WWW site information DB 151 is set to 1
Retrieve WWW site information record by record.

Step 302) WWW site information DB
It is checked whether the record fetch from 151 has reached the last record. If it is not the end of the record, the process proceeds to step 303, and if it is the last record, the process proceeds to step 311.

Step 303) If it is not the end of the record, the WWW page is acquired from the URL of the retrieved record using the WWW page collection unit 14, and again,
The process of step 301 is performed.

Step 311) If the record retrieved in step 302 is the last record, the WW collected by the WWW page collection unit 14
