Abstract: It is necessary to use expert knowledge of networks and computers to reduce the burden on users when providing high-quality communication services to non-expert users in ubiquitous information environments. We have been working on the systematic support of circulation of expert knowledge to meet that need. In this paper, we propose a new Knowledge Circulation Framework (KCF) for ubiquitous service provision: uKCF. We applied uKCF to service control for a ubiquitous videoconferencing system. The experimental results show that the proposed system can provide better and more stable service by improving adaptability to various ubiquitous computing environments.

Keywords: ubiquitous information environments; agents; knowledge base; knowledge circulation; QoS control; ubiquitous services; quality of service; communication services; expert knowledge; ubiquitous service provision; videoconferencing; multi-agent systems; MAS; agent based systems.
