Publishing and Discovery of intentional services: Goal-driven approach

With the increasing growth in popularity of Web services, discovering relevant Web services becomes a significant challenge. The introduction of intentional services is necessary to bridge the gap between low level, technical software-service descriptions and high level, strategic expressions of business needs for services. Current Web Services technology based on UDDI and WSDL does not make use of this “intention” and therefore fails to address the problem of matching between capabilities of services and business user needs. In this research work, we propose publishing and discovery of services based on intentions they satisfy by extending the actual registry to build the intentional one. We also focus on the part of discovery of intentional services concerning the formulation of the user’s requests. Our contribution consists of proposing a goal meta-model for user’s request using ontologies, the descriptor to be published in the registry and the matching algorithms between services’ intentions and users’ goals using similarity metrics.
