Under the service-oriented circumstances, developers can rapidly create applications through Web service composition, but the wholly intellectualized automatic composition is a very complicated process. So, many applications and research about composite services emphasize on semi-automatic mode. This paper presents independent global constrains-aware Web service composition method based on color Petri...
This paper proposes an automatic Web service composition method which considers both services input-output type compatibility and behavioral constraint compatibility based on Petri nets to raise the composition reliability. It presents a novel technique for discovering semantic relations between pre and post conditions of different services using their ontological descriptions. The technique takes...
At present, the service composition has been a popular research. It is unrealistic to manually analyze and compose the existing services appearing with tremendous growth recently. So, many applications and research about composite services emphasize on semi-automatic mode. In semi-automatic service composition, developers should construct the process model according to concrete application requirement,...
This paper proposes an automatic Web services composition method that satisfies the userpsilas request efficiently. Using the method, the available services in a local repository described in OWL-S are translated into a set of production rules, and the dependency rules of the Web services are established using interface matchmaking. We choose reasoning Petri nets (RPN) as the model of this set of...
The use of services, especially Web services, became a common practice. In Web services, standard communication protocols and simple broker-request architectures are needed to facilitate exchange of services, and this standardization simplifies interoperability. In the coming few years, services are expected to dominate software industry. There are increasing amount of Web services being made available...
