Beehive: A System for Cooperative Filtering and Sharing of Information Bernardo A. Huberman and Michael Kaminsky Dynamics of Computation Group Xerox Palo Alto Research Center Palo Alto, CA 94304 Abstract We have designed and implemented a distributed system for social sharing and filtering of in- formation. It relies on the automatic recording of the behavior and interactions of members of communities of practice. The system automatically updates membership in informal communi- ties at regular intervals and provides a simple and intuitive interface for distributing relevant in- formation among its members.
