The Practical Application of Semantic Web Technologies for Situation Awareness

The grand vision of the Semantic Web has led to the development of new technologies intended to serve as the groundwork for its eventual realization. Primary among these technologies is the Web ontology language OWL [1] and its more recent extension in the form of the Semantic Web rule language SWRL [2]. These languages are built upon decades of research and real-world experience in the areas of knowledge representation, automated reasoning and rule-based systems. It is fair to say that they represent (in part) the cutting edge of practical technologies for realizing intelligent agents and advanced applications. As such, these technologies are applicable to problems well beyond that represented by the Semantic Web proper. Versatile Information Systems, Inc. is committed to the development of formal yet practical reasoning systems applied to problems in the area of situation awareness and information fusion. Our recent endeavors in this area have been grounded in Semantic Web technologies and have had occasion to stress them to some of their practical limits [3,4,5,6]. In our demonstration we will present the current state of our Situation Awareness Assistant (SAWA) and show how it makes use of OWL and SWRL. We will also present two supporting applications, a consistency checker for OWL documents and a graphical editor for SWRL.
