Research On Web Service Composition Technology Based On The Agent

Web Service is a kind of energetic distribute computer model in recent years,which can handle application compiled and composed in different platform, different programming language or in different application modules seamlessly and mutually. More and more enterprises distribute their applications as Web Service, but with gradually complicated applications of striding over enterprise, single Web Service is more and more difficult satisfy actual requirement. The application needs to composite many different business function Web Services to construct complicated compositon Web Service according to certain business logical process, to satisfy complicated business logical requirement through executting composition Web Service.The thesis has deeply researched the technology of the available Web Service composition on the background of Web Service technology. It also introduces Agent technology to composite Web Services to build composition Web Service model based on the Agent; On basis of integration of Web Service technology with semantic web technology, the thesis has carried out semantic extension on UDDI and suggested the matching algorithm and the compositing algorithm of Web Service; By cooperation with Multi-Agent System,accomplishing Web Services matching and Web Services compositing, the thesis realizes the flow of composition Web Services to dynamically process.The technology of Web Service composition based on the Agent has fused the Agent intelligence property, Web Service opening and striding over platform characteristic.Comparing to tradition Web Service composition method, it is dynamic, nimble Web Service composition mechanism,which is a good scheme resolves Web Service compositing.
