Abstract:

With the continual development of the Web Services applications, it is necessary to compose the existing Web Services dynamically according to servicerequests. This paper proposes a model of Web Services ontology using electronic commerce domain ontology and a dynamic Web Services composition framework and method based on semantics. The framework includes a Web Services description model, a request parser model and a service composition model. Finally, we give its implemention in a shopping system.

Key words: ontology, semantics ;Web Services, dynamic composition of services
