Tools for Composite Web Services: A Short Overview Richard Hull and Jianwen Su   View Paper (PDF)   Return to June 2005, Volume 34, Number 2 Abstract Web services technologies enable flexible and dynamic interoperation of autonomous software and information systems. A central challenge is the development of modeling techniques and tools for eanbling the (semi-)automatic composition and analysis of these services, taking into account their semantic and behavioral properties. This paper presents an overview of the fundamental assumptions and concepts underlying current work on service composition, and provides a sampling of key results in the area. It also provides a brief tour of several composition models including semantic web services, the "Roman" model, and the Mealy / conversation model. ©2006 Association for Computing Machinery
