Semantic description of location based web services using an extensible location ontology
Rob L. G. Lemmens, ME de Vries · University of Twente Research Information · 2004
A growing number of Web services, including Location Based Services (LBS) is becoming available to the public, but it is difficult to find them and to judge whether they could be used in combination with other services. This is partly caused by the fact that conventional service descriptions fall short in capturing the semantics of services. In this paper we present alternative ways to enrich service descriptions with semantic information, focussing on the domain of LBS. These descriptions refer to concepts in an extensible location ontology that is expressed in the Web Ontology Language (OWL). We demonstrate the adequacy of a reasoner to perform matchmaking between the descriptions of a required service and advertised services. Despite the current limitations, the presented method allows for much more expressive descriptions than WSDL and can be used to semantically enable OpenGIS GetCapabilities in discovery and service chaining mechanisms.
