Semantic Web Service Composition in the NeP4B Project: Challenges and Architectural Issues

Abstract

Semantic Web service discovery and composition frameworks proposed so far assume for the most part a centralized registry that holds information of all the Web services available at any given time. This solution does not well cope with the scalability and flexibility requirements of dynamic, fast changing contexts. As part of the NeP4B project, in this paper we propose an alternative peer to peer architecture based on the Goal concept
