Web services offer a promising approach to accomplish a loose coupling of processes across organizational boundaries. Several industry standards have been developed to describe process or service related information. Although these standards capture similar concepts, they nonetheless rely on diverging interpretations of processes and their components. In this paper, we present an approach to facilitate the search for services, where services and requests can be described using heterogeneous standards. To enable the mapping of a request to different service description standards, formal ontologies are used. Ontologies are related on the basis of similarity relations in order to translate between elements of different service descriptions. The resulting translation is used to process a request and find an adequate service. We present a top-down and a bottom-up method to implement this kind of request processing.
