Semantic Web Service Automatic Execution And Monitor

As the most novel distributed compute model, Web Service has the advantages: loose couple, technology-independent, platform-independent, it could integrate enterprise applications in an effective way. By introducing semantic into Web Service, a new technology—Semantic Web Service builds the basis for searching, compositing, executing and monitoring Web Service automatically.Web Service execution and monitoring are close combinative technologies. As a key phase in Web Service composition, the automatic degree of Web Service execution decides whether it could implement automatic Web Service composition or not; By collecting execution data, Web Service monitoring computes Quality of Service (Qos) which is applied to Web Service selection, it make users select Web Service more effectively. Therefore, it is very important to research Web Service automatic execution and monitoring technology.The objective of the paper is to research, design and implement a Semantic Web Service automatic execution platform, which functions are: supporting Web Service executing automatically, failure recovery dynamically; supporting Web Service monitoring and Qos computing which is applied to Web Service selection.This paper is separated into eight chapters. The chapter one introduces the research background and main work accomplished during the paper writing process. In the chapter two and three, Web Service and Semantic Web Service technology, as well as Web Service execution engine and Qos technology are briefly discussed. The chapter four expatiate the theory of Web Service automatic execution and dynamic failure recovery. In the chapter five, Web Service monitoring technology and Qos computation arithmetic which applied to Web Service selection are analyzing. The chapter six introduces the design and implementation of Semantic Web Service automatic execution platform. In the chapter seven, based on the listed testing results, the capability and advantages of the platform are estimated. Finally, the gains and prospects I have been awarded of in the process of writing this paper are summarized.
