Assessment of Upper Ontologies and provide adequate upper ontology reqirements for military, sequrity and crisis management applications

With the advancement of technology progress, every time the number, diversity and quality of information ranging from conflict spaces, military, security and crisis are added. Ontology is the perfect tool for modeling knowledge in a domain that what is going on is modeleded in terms of concepts, characteristics, concepts, principles and rules governing the relations between them. The potential of Ontology modeling in comparison with other methods is higher. To reduce the effort for domain modeling, the upper ontology created. This ontology has very high level of abstraction. The benefits of upper ontology are: demystify and understand the meaning of concepts and relationships in domain ontology, to compare it with other ontologies, possibility of mapping between ontologies, composition and translation from one ontology to the other, creating a common language across domains for example crisis management and joint operations situations. In this study, different upper ontologies investigated and the strengths and weaknesses extracted, then different criteria to assess the upper ontologies and the comparison between them are described. Based on this comparison, the important criteria in the selection of upper ontology for developing indigenous ontology for military, security and crisis management domains are made and conclusions are drawn.
