BeAware! - Situation Awareness, the Ontology-Driven Way
Sprache des Titels:

Original Kurzfassung:
Information overload is a severe problem for human operators of large-scale control systems as,
for example, encountered in the domain of road traffic management. Operators of such systems
are at risk to lack situation awareness, because existing systems focus on the mere presentation of
the available information on graphical user interfaces—thus endangering the timely and correct
identification, resolution, and prevention of critical situations. In recent years, ontology-based
approaches to situation awareness featuring a semantically richer knowledge model have
emerged. However, current approaches are either highly domain-specific or have, in case they are
domain-independent, shortcomings regarding their reusability.
In this paper, we present our experience gained fromthe development of BeAware!, a framework
for ontology-driven information systemsaiming at increasing an operator's situation awareness. In
contrast to existing domain-independent approaches, BeAware!'s ontology introduces the concept
of spatio-temporal primitive relations between observed real-world objects thereby improving the
reusability of the framework. To show its applicability, a prototype of BeAware! has been
implemented in the domain of road trafficmanagement. An overviewof this prototype and lessons
learned for the development of ontology-driven information systems complete our contribution.
