In this paper, we propose a feedback based framework for semiautomatic composition of Web services. In the framework, whenever a service process is constructed by composing Web services, the connection patterns of Web services in the service process are analyzed and registered in terms of data and control flows. Also a method of measuring the degree of(More)
AbsImcIIn this paper, we propose adaptive QoS(Qualily of Service) control mechanism and a architecture using multiapnt framework to improve flexibility of a videoconference system. The proposed mKhanism realizes more flexibility by changing their Qos control strategies dynamically. We implemented the mechanism, and our prototype system shows its CapabiIiIy(More)
In this paper, we propose a new agent-based flexible videoconference system (AVCS) by modifying videoconference manger (VCM) agent in a conventional flexible videoconference system (FVCS). The proposed AVCS can more flexibly cope with changes in working conditions during videoconferencing than the conventional FVCS. It is because an automatic parameter(More)
