 note = {WWWの検索エンジンでは、1回の検索で数万件の結果が得られることが珍しくない。しかし、その過半数が検索意図に適合しないのが普通である。この検索結果を利用者の検索意図に近づけつつ数百件程度まで絞り込んでいくことが重要である。本稿では、検索結果の絞り込みを支援するための、検索結果の可視化と追加検索語候補提示を行うユーザインタフェースについて述べる。, We often get thousands of URLs by sending a query to a WWW search engine. However, it is very often that most of the search results does not match our purposes. Providing that the user's cost of information retrieval is the time spent for browsing information which does not match the user's purpose, the allowable cost for general users may be less than hundreds of URLs. Thus it is clearly important for the users of the WWW search engines to reduce the search results to less than a hundred URLs. The task of refining query to reduce the search results is the most important step of the process of using search engines. In this paper, an user interface which helps refining query is discussed. Our prototype interface is also described.},
