Instance-based Service Discovery with WSMO/WSML and WSMX

In this chapter we present the solution based on WSMO[6], WSML [8]) and WSMX[3] to solving SWS Challenge discovery tasks. Web Service Modeling Ontology (WSMO) provides a model for Semantic Web services used for defining ontologies, services, goals and mediators. Web Service Modelling Language (WSML) provides a family of ontology languages used to formally describe WSMO elements used for service modelling, while Web Service Execution Environment (WSMX) is a middleware platform used for discovery, composition, execution and mediation of Semantic Web services. WSMO, WSML and WSMX form a coherent framework covering all aspects of the Semantic Web services that we use to address SWS Challenge discovery scenario.
