Abstract

The InfoFinder agent learnes profiles of user interests from sample documents submitted by the user while browsing, without requiring the user to complete a questionnaire about interests in various documents. It learns general profiles from the documents by heuristically extracting phrases from the documents taht are likely to represent the topic of the document. Its learning algorithm generates a search tree, which is then translated into a Boolean search string for submission to a generic search engine. It sends the user regular updates on documents without requiring the user to take the initiative to access the agent
