Run-time ontology on the basis of event notification service

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 (IEO) 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.
