Abstract

A system and method are provided that use explicitly and implicitly derived models of user information needs and content and presentation preferences together with relevancy feedback to expand a user'"'"'s original query to the most related terms in a corpus and/or to allow the user to provide interactive feedback to enhance the relevance of selected news stories and display profile of the selected news stories. By personalizing both the selection of stories and the form in which they are delivered, users are provided with tailored broadcast news.
