Semantic Web Service Coordination

Semantic service coordination aims at the coherent and efficient discovery, composition, negotiation, and execution of semantic Web services in a given environment and application context. What makes coordination of services in the semantic Web different from its counterpart in the Web is its far more advanced degree of automation through means of logic based reasoning on heterogeneous service and data semantics. In this chapter, we only focus on approaches to semantic discovery and composition planning of semantic Web services, and briefly comment on their interrelationships and selected open problems of both fields. For reasons of space limitations, the set of presented examples is representative but not exhaustive.
