Research in Enterprise Applications of Dynamic Web Service Composition Methods and Models

The paper summarizes current technologies of dynamic Web service composition. Then, based on the existing technologies, we raise a new solution for dynamic Web service composition. We make use of the knowledge of domain ontology. On the one hand, the user´s requirement was broken down into a series of abstract Web services, according to the logic of business processes. On the other hand, through establishing the Web service index storehouse, we gather the existing atomic services and composite services in domain ontology. By semantic matching between the abstract services and the atomic services or the composite services, the executable Web services composition could be obtained. Finally, an application example of the solution is showed.
