Abstract:
With the development of Web services, semantics is introduced into Web services, and the information recognition ability can be enhanced with the semantic description of Web services. Thus, the technology of service composition and binding can be improved. At present, the main method of service composition, discovery, binding and replacement is similarity computing based on an ontology tree. However, constructing the ontology tree and deploying the concepts in it are difficult, and the operability of service
composition with similarity computing cannot meet user requirements. To solve the above problem, a new method of service composition is introduced based on semantic vocabulary. The constructing methods of the semantic vocabulary, concept replacement, service clustering, and service composition are given. Finally, the validity and correctness of proposed methods are illustrated by simulations and the comparative analysis of simulation results.
