Dynamic Selection of Best Service in Semantic Web Service Community

How to precisely and meaningfully represent service capability and what is really detectable best service in available service space are two inescapable issues we must take into account when exploring dynamic selection of the best service. In this paper, Web Service Community (WSC) is proposed as a promising computational infrastructure in which web service is described in the way of concordant combination of explicit representation and implicit representation and attention on both commonness and peculiarity of service individual. In the context of WSC, we propose an efficient approach of best service selection based on foregone service experiences by manifesting directly the competition for same or similar function requests among Web service candidates.
