What would it mean to browse collaboratively? In business meetings or family situations, several people may be attending a browsing session, even if only one "controls" the browser. The success of browsing depends on satisfying the interests of the passive participants as well. We are working on an agent that will provide assistance to group browsing, representing the interests of the entire group, and performing "reconnaissance" in anticipation of what pages are likely to be of common interest. It features automatic detection of the presence of users, acquisition of information about the interests of users, automated "channel surfing," and dynamic display of the user profiles and explanation of recommendations.
