英文摘要: The software services and service cooperation represented by web service are becoming the mainstream of Internet application, and the organization and automatic construction of massive web service are the core support technologies. In order to meet the requirements of the large scale web service publishing, discovery and composition and improve the scalability of the semantic web service system, P2P computing and publish subscribe mechanism are used to construct an active P2P architecture. The dynamic scalable web service organization model is studied, the web service status active monitoring method is given, and the formal description is analyzed based on Petri net theory. The semantic, concurrency and net flow of P2P system is optimized for the active P2P architecture. Based on the active P2P architecture service organization model, the automated construction of large scale semantic web service including intelligent discovery, selection and composition is discussed, the math model of intelligent service selection and its distributed fast solution algorithm are proposed, and the calculus of communicating system and description logic are combined to realize the character depiction and validation of automatic construction. Finally, given the evaluation mechanism and integrated phased research results, a service o
