ed Abstract an extended abstract of [11]. Service-oriented computing is emerging as a new paradigm based on autonomous, platform-independent computational entities, called services, that can be described, published, and dynamically discovered and assembled. An important part of a service is its public interface, which describes the service and should be independent of the technique used for implementing it. A service's interface can describe various aspects of the service, such as the service's location and communication protocols that can be used for interacting with the service. In [11], we confine ourselves to the investigation of those parts of a service's interface that describe the functionality offered to a service requester. Not all service specification approaches support this. Services that are endowed with such functional descriptions are often called semantic web services [6]. Semantic web services facilitate more effective (semi-)automatic service discovery ...
