Research On Rule-Based Web Services Composition

Web Services technology give out a method to realize the reuse of software component. And the technology of Web services composition is the research focus recently. It determined by the methodology of Web services development. The main idea of web services and web services based services oriented architecture is deliver the basic operations as services to achieve the intention of reuse. So it is necessary to discover and compose the web services to satisfy the user's demands. The widely used web services description language (WSDL) in industry can't satisfy the need of web services automatic discover, operation, composition, observe and recover because lacking of well defined semantic information.This thesis choose Web services composition as research field, the major work and innovations in this paper are as follows:1. Analysis the relationship between web services and web services composition, then introduce the necessity of web services composition; Introduce Rule-Based method to the field of web services composition to satisfy the need of web services selection.2. Choose the suitable rule representation and reasoning algorithm. Improve the performance of traditional reasoning algorithm, Design suitable method to evaluate the time and space performance of the reasoning system; prove the advantage compare to the traditional reasoning algorithm.3. Design a basic web service assembly framework to integrate the rule engine with the traditional enterprise framework; realize the intelligent assembly of web services.
