Cooperative Information Agents VI

These are the proceedings of the Sixth International Workshop on Cooperative Information Agents (CIA 2002), held at the Universidad de Rey Juan Carlos in Madrid, Spain, September 18-20, 2002. It was colocated with the Third Int- national Workshop on Engineering Societies in the Agents World (ESAW 2002). Since 1997 the annual CIA workshop series has aimed to provide an open forum for all parties interested in the research and development of intelligent infor- tion agents for the Internet and Web. Each event in this renowned series attempts to capture the intrinsic interdisciplinary nature of this research area by calling for contributions from di?erent research communities, and by promoting open and informative discussions on all related topics. In keeping with its tradition, this year's workshop featured a sequence of regular and invited talks of excellence given by leading experts in the ?elds related to information agent technology. These talks covered a broad area of topics of - terest, such as information agents for mobile computing environments as well as information gathering, exchange, management, and collaborative recommender systems. Other topics included agent interaction and communication, negot- tion strategies for purchasing relevant information, and agent-based distributed knowledge management.
