Abstract: Ontology is a term deriving from philosophy but lately very often used in the context
of knowledge management. Ontologies help to provide unambiguous definitions of terms, relationships
among them and deliver human-like understanding of knowledge to IT systems. Going even further,
they can automate some of the processes giving the opportunity to get rid of “the man in the loop”.
The paper presents the INSIGMA event run-time ontology that is used by the Event Notification
Service (ENS) to automate the process of notifying public safety services about the dangers related
to the traffic and accidents on the roads. Special attention is paid to the ontology content, event notification
service and the reasoning module that is responsible for inferring knowledge on the basis
of the T-Box and A-box ontology statements.
Keywords: ontology; run-time ontology; event notification service; OWL; reasoning; domain model
I. Introduction
Ontologies [1,2] are mainly well–formed hierarchical descriptions of the domain
of knowledge that have their roots in philosophy. While very much appreciated
in the knowledge management and logics, they are also getting more and more
important in the information systems domain where they are used to perform
certain tasks in the system. In this case they are called run-time ontologies.
Run-time ontology is applied during the system operation and usually
helps to deliver certain functionality. It is not only developed to describe the domain
of knowledge in the philosophical manner but to build a model enabling
to derive additional information and perform reasoning. This was also the case
in the INSIGMA project that is supported by the funds from European Ministry
of Regional Development within one the Polish National Strategic Reference Frameworks
– Innovative Economy. It is carried out by four Polish academic, research
and commercial bodies: AGH – consortium leader, MCI, MUT and WSTKT.
Work has been co-financed by the European Regional Development Fund under the Innovative Economy
Operational Programme, INSIGMA project no.POIG.01.01.0200-062/09.
