COLLABORATIVE INFORMATION GATHERING

The combination of push and pull information retrieval technology can benefit from collaborative information gathering schemes. In this paper we outline an approach that combines a pull technology (Knowl- edge Brokers) with a push technology (Knowledge Pump) in a community-based environment. Appropriate toolkits supporting synchronous collaboration on the World Wide Web are briefly introduced. A PlaceWare- based implementation illustrates the synchronous construction of queries and the publication of search activities and results supported by the push component.
