The keyword (for example, “yakitori”) associated with the URL (for example, http://sss.co.jp/otsumami) of the link included in the Web page indicated by the information specifying the link 201 to “ The weight value of the keyword in the Web page (for example, “9.0” associated with “yakitori”) is acquired.

  Then, the degree-of-association calculating unit 35 calls and compares “yakitori”, which is a keyword included in the linked Web page, and “yakitori”, which is a query stored in the query temporary storage unit 41, and is identical to the query. The keyword “yakitori” is extracted, and “9.0”, which is the weighted value of the extracted keyword “yakitori”, is calculated as the degree of association between the query and the content of the linked web page. Send.

Next, as shown in FIG. 12, a web page 300 with a link destination relevance level configured by the page configuration unit 18 is displayed on the user terminal 1.
On the web page 300 with the link destination relevance level, the relevance level display item 302 is superimposed on the normal web page 301 that is the link destination web page of the selected link in the vicinity of the “snacks” that are links included in the normal web page 301. Is displayed. The relevance level display item 302 displays the relevance level “9.0” between the query “yakitori”, the contents of the Web page “link” “query”, and the query. Further, the relevance level display item 302 may be displayed, for example, when the relevance level button 80 on the toolbar is clicked with the cursor 90.

  By using the relevance level display item 302 as described above, the user can recognize that the “snacks” as the link destination has information having a high relevance level with the “yakitori” as the query.
