Abstract
A method and apparatus for efficiently matching a large collection of user profiles against a large volume of data in a webcasting system. The method removes redundant patterns in user profiles and information content to improve matching performance based on a Boolean-based query language. Users can select desired information content by choosing a set of predicates to assert the properties for each cyberspace document desired. Boolean operators of AND, OR and NOT connect predicates together on the information items that will be pushed to them. The method includes dynamic cost/credit adjustment based profile indexing and matching.
