A novel approach for parallel Web Service composition

This paper examines the use of constraint-based configuration for the Automatic composition of Web Services. Automatic composition of web services has drawn a great deal of attention recently. Here we use composition to refer the approaches where a significant part of this process has been automated. By composition, we mean taking advantage of currently existing web services to provide a new service that does not exist on its own. Therefore, in order to have a more complex service, we can use some semantically related simpler web services and execute them in such a way that the whole set provides the desired service. Web service enables people work in cooperation and greatly help people share and reuse knowledge on the web. Based on the principle of Interface Automata, this paper provides a design method of web service composition, in which each web service corresponds to an Interface automata model and use the Interface Automata composition process to represent the web composition.
