Service Adaptation Using AI Planning Techniques

This paper presents a method to automatically construct a sequence of mediation services needed to adapt an existing service interface into a required new form. The expected use of this method is mainly in heterogeneous service-oriented environments where Web Service and other technologies have to coexist. Unlike most other works in the area of Web Service composition, we do not focus on semantics of the services involved, but merely on technical aspects of their communication. The method in its present form deals with aspects of incompatible message contents, formats, transport protocols, and security mechanisms. The required sequence of mediation services is generated using an action-based planner. The method has been implemented as a research prototype to allow experimenting at this stage of research.
