Enabling Collaboration in the Semantic Grid: Survey of Web Service Composition Approaches

Web Service is loosely coupled highly accessible distributed computing technology that can expose applications beyond the firewall. Composition of Web Services has received much attention from the business and the research community. Composition techniques are classified as static, dynamic and semi-automatic composition, each addressing different application areas and requirements. In this contribution we analyze workflow-based and semantic-based composition approaches, primarily focusing on the facilitation to the service participants and the scalability required in a Grid-based environment.
