Abstract
Information Fusion is the process of utilizing information from various sources to produce knowledge about objects and situations in order to assist humans in decision making. It is argued here that fusion processes would be better equipped to produce these entities estimates if designed in conjunction with formal ontologies. Such ontologies can provide fusion system designers with a comprehensive, and computationally tractable, phenomenological description of a given domain. A properly conceived formal ontology is necessary to provide a structure for analyses of domain-specific objects, object attributes, and relations and to assure both interoperability and reusability of the designed fusion system for different domains. In this sense, a formal ontology informs the fusion process by providing a phenomenological description of a given state of affairs. At the same time the fusion process constrains the formal ontology in terms of its size, scope, and relevance for certain decision-making needs. This report presents ontology related concepts for building a threat ontology (ThrO) to be used in various information fusion applications involving threats.
