Ontologies have moved beyond the domains o … Ontologies have moved beyond the domains of library science, philosophy, and knowledge representation and are now being used to facilitate mainstream applications in all areas concerning information. Information fusion applications can benefit from access to information contained in ontologies such as controlled vocabularies, term meanings, term relationships, and logical implications of term usage. We will define ontologies by introducing the notion of an ontology spectrum ranging from simple vocabulary information to more complex knowledge structures. We will point to examples of ontologies available at different points along the spectrum. We identify how ontologies at differing points along the spectrum may be used to support improvements in information management solutions ranging from better search to precise semantic matching, noting that all of the benefits can be applied to information fusion. We will discuss the potential impact, benefits, and costs of using ontologies in information fusion applications. logies in information fusion applications.
