An Intelligent Framework for Dynamic Web Services composition in the Semantic Web

The last decade has witnessed an explosion of application services delivered electronically, ranging from e-commerce and Internet information service, to services that facilitate trading between business partners, better known as Business-to-Business (B2B) relationships. Traditionally these services are facilitated by distributed technologies such as RPC, CORBA, RMI, and more recently Web services.

Extensive use of XML (eXtensible Markup Language) for messaging, discovery, and description makes Web services platform, language neutral technology and provides edge over other distributed technologies. Moreover, multiple Web services can be integrated either to provide a new, value-added service to the end-user or to facilitate co-operation between various business partners. This integration of Web services is called "Web services composition".

Despite the evident popularity of Web services as a platform and language-neutral distributed computing paradigm and the value-added dimension that composition adds to it, the practical adoption of the technology is still to gather the expected pace. Assistance with the facilitation of the composition process to the service providers and the composers, play a major role in encouraging the adoption of the Web services technology.

In our DYnamic SErvices Composition (DYSEC) research project, We aims to contribute towards promoting the adoption of the Web service technology by implementing a development framework for dynamic Web services composition to reduce the service providers' and composers' burden of composition of Web services.
