Automatic Composition of Semantic Web Services-based Alignment of OWL-S

Web services transform the Web into a platform for distributed components, heterogeneous, loosely coupled and integrated automatically. This technology is now widely used as a support for interoperability between distributed applications, which operate independently of the design features and technical specifications in order to achieve a feature previously established. The creation of a complex distributed application can be obtained by the composition of Web services. To build our platform-based semantic Web services, we strive to establish an architecture in which the semantic Web services interact with each other only, so they allow compositions of Web services to meet the up a different user requirements. The aim of our work is to achieve semantic interoperability in a heterogeneous, distributed architecture, based on the automatic dialing services Semantic Web. The special feature of this architecture is to place the alignment of OWL-S in the heart of this process, depending on the quality of services (QoS).
