Situational reasoning - a practical OWL use case

Abstract

In this paper we study the case of situational reasoning on ontological descriptions in context-aware applications. We therefore discuss the logical foundations of W3C's standard ontology language OWL and examine how this modeling language can be used to express a user's situation. In a practical scenario and through the use of standard semantic Web components and toolkits, we exemplify how basic reasoning services can be utilized to build and maintain well-founded context models.
