A User-Centric WS-Mediator Framework for on-the-fly Web Service Composition

Nowadays, the effective and adaptive dynamic Web service composition is a major challenge for a real success of Web services among ordinary users. For the latter, and from the viewpoint of a user centric paradigm, existing work has limitation on their agility to create a composed service on the fly according to the desire/need of an end-user at a given time/place. This article presents our approach which consists in providing a comprehensive framework for a user centric WS-mediator which is capable of dynamic service composition. It is based on a composition engine which follows user’s specific needs and which yields a composed service through a WS knowledge base. Users can mash up the services at run time with their own logic and have a fully dynamic composition with context adaptation through a WS-mediator that is also capable of supporting the semantic web.
