Key Technology Research on Dynamic Web Service Composition Based on Semantic Web

Complex services may be dynamically composed through combining distributed components. By properly selecting and combining components on demand, a new application may be composed from a set of components. It enables quick development of new application functionality through the reuse of the components. But existing service composition systems often be implemented by using its syntax not its semantic. In order to enable semantics-based dynamic service composition, this paper analyzes relative service composition mechanism. Then it proposes a dynamic composition service framework based on semantic and implements its key technology. These techniques can bring flexibility and adaptability to future application.
