1 F2001 Technical Papers Web Adaptive User Interface of a Web Search Engine by Organizing Page Information Agents Seiji Yamada Fumihiko Murase CISS, IGSSE, Tokyo Institute of Technology yamada@ymd.dis.titech.ac.jp, murase@ymd.dis.titech.ac.jp, keywords: page information agent, the WWW, adaptive interface, a search engine, organization Summary In this paper, we develop an organization method of page information agents for adaptive interface between a user and a Web search engine. Though a Web search engine indicates a hit list of Web pages to user s query using a large database, they includes many useless ones. Thus a user has to select useful Web pages from them with page information indicated on the hit list, and actually fetch the Web page for investigating the relevance. Unfortunately, since the page information on a hit list is neither sufficient nor necessary for a user, the adequate information is necessary for valid selection. However which information is adequate depends on a user and a task. Hence we propose adaptive interface AOAI in which different page information agents are organized through man-machine interaction. In AOAI, the page information agents indicating different page information on a hit list like the file-size, network traffic and a page title are prepared at first. A user evaluates them through searching with a search engine, and the agents are organized based on the evaluation. As results, different organizations are achieved depending on a user and a task. Finally we make experiments with subjects and find out AOAI is promising for adaptive interface between a user and a search engine. 1.
