What is wrong with Web services Discovery?

Abstract

Various proposals for automating the discovery of Web services are available. Most of them regard the terms service and Web service as synonymous. We believe these two terms are not equivalent and it is relevant to distinguish them and to explore their relation. We argue that this fundamental distinction is necessary in order to achieve scalable and realistic Semantic Web service Discovery. Thus, we advocate a proper conceptual model following the distinction of these notions. Our model takes into account Goals, Abstract Goals, Web services and Services, in order to enable efficient and scalable discovery which matches the expectations of service requesters.
