A New Approach for Web Service Composition Based on Semantic

Web service composition,which compose existing Web service to satisfy the application requirement, become the key of the enterprise integration application in network.But existing Web service composition is mostly based on syntax ,it is very difficult to compose Web services together in heterogeneous with syntax but in accord with function.In order to resolve the heterogeneity between Web services and improve the quality of Web service composition,we propose an new approach based-semantic for Web service composition,which divides the composition process into two phases.Based on the approach,we analyse the potential interdependency of logic temporal and semantic data between Web services based on business logic,specify the composable structure,and general composition Web services on strategy.During the execution of composition Web service,expatiate the data transfer mechanism between Web services and invoking course of every member Web services within the composition Web service.
