Broadway: A Case-Based System for Cooperative Information Browsing on the World-Wide-Web

The World Wide Web is a huge hypermedia where finding relevant documents is not an easy task. In this paper, we present our case-based system for cooperative information browsing, called Broadway. Broadway follows a group of users during their navigations on the WWW (proxy-based architecture) and advises them by displaying a list of potentially relevant documents to visit next. Broadway uses case-based reasoning to reuse precise experiences derived from past navigations with a time-extended situation assessment: the advice are based mainly on similarity of ordered sequence of past accessed documents. In addition, the dynamic nature of the WWW is addressed in the reuse step and with a specific method for case forgetting.
