Service composition engine based on service-ontology

Abstract

With the rapid increasing of the number of services in Web environment, single or simple composition of the service is unable to provide high-quality service for requesters. Although dynamic service composition provides the automatic composition methods for machines, it cannot handle complex service requests. The main objective of researching Semantic Web is to extend the current World- Wide-Web, which makes all the information in Internet semantic. This paper arms to analyzes the main features of the Web Service. Then, with the definition and application of ontology, we propose the concept and definition format of service-ontology, and with the construction of service composition and corresponding algorithm, we apply it in the dynamic Web service composition application. Combined with intelligent smart transcript repository and ontology knowledge repository, the architecture provides the static and dynamic composition environments to facilitate knowledge accumulation, logic inference, binding web service and creation of process driven model. The approach considers the semantics of services along with the quality and the efficiency of the composition. Finally, based on the prototype system to validate the approach, the results of experiment prove that the Service Composition Engine is feasible and effective.
