One such a threat is shoulder-launched missiles which are portable, easy to use and easy to come by. To counter this the military deploy various kinds of countermeasures on aircraft against these attacks. In order to assist in the development, evaluation and deployment of the countermeasures, modeling and simulation are used. One such a system is the Optronic Scene Simulator, an engineering tool used to model and evaluate infra-red countermeasures to make recommendations for the deployment thereof. Ontologies are no longer a foreign concept in the computer and information sciences eld - it plays a valuable role in making systems more valuable. An ontology, Simtology, was developed to support the the simulation system in various ways such as providing a shared vocabulary, improve understanding of the concepts in the environment and add value through suitable functionality.}, year = {2012}, number = {98-110}, }
