Original Kurzfassung:
Human operators of large-scale control systems face the prob-
lem of information overload induced by the large amount of
information provided by multiple heterogeneous and highly-
dynamic information sources. Situation-aware information
systems support operators by the aggregation of the avail-
able information to meaningful situations. Ontologies are
a promising technology for realizing such systems, because
of their semantically-rich kind of knowledge representation.
The cross-cutting role of ontologies and the streaming char-
acter of situation awareness, however, challenge the design
of an appropriate software architecture. In this paper, we
propose a domain-independent software architecture based
on a core ontology for situation awareness which leverages
the reusability and the scalability of involved software com-
ponents. This is achieved by the application of the well-
known software architecture pattern pipes-and-filters. The
proposed architecture is demonstrated by examples from the
field of road traffic management. In addition, we contribute
several lessons learned which should be helpful for develop-
ing ontology-driven information systems in general.
