Trends of Web Service Composition

Abstract

Web service composition is about maximizing the benefits of different Web services by composing a certain number of Web services to deliver a fully end-to-end service. This paper presents a review of the two major trends of Web service compositions: top-down composition and bottom-up composition. The top-down composition starts with a well-defined goal and search criteria before searching for the composition, while the goal and search criteria in the bottom-up composition are not well defined. The bottom-up composition is often called Web service mining. Web service mining is a new trend that aims at discovering useful and interesting compositions of existing Web services.
