Advanced Profile Similarity to Enhance Semantic Web Services Matching

Abstract

In this paper, we present a fine-grained matching method of the services based on a hybrid similarity measure. We propose a novel encoding of the services descriptions, allowing the match between a request and an advertisement in order to make more efficient publishing and searching process of Web services and reduce the number of comparisons required. By this kind of similarity between concepts of profile, a precise matching method is developed to match the profile of the Web services and user. Searching process in the UDDI registry is done via an algorithm that allows us to extract the search concepts and retrieve the topk services, thereby further reducing the search engine's response time. The approach is illustrated through some experiments both on real and synthetic data to demonstrate its consistency and effectiveness.

How Can Transactional Semantics Enhance the Commit Rate of Context-aware Service Composition in Advanced Pervasive Systems?

“…Transactional properties are considered extra-functional properties of a service. In the field of Web Services [40,41], these properties are generally described by the use of the WS-Policy language [6]. Other approaches such as [7] and [8] have proposed to extend the WSDL description to describe the transactional behavior of web services.…”
