Using Ontologies to Conceptualize the Aeronautic Domain

In this paper we describe the technology of ontologies and their use in the conceptualization of the aeronautic domain. Conceptualization is needed in order to understand a domain, to construct artifacts and to transfer knowledge between humans and systems. Next to an explanation of ontologies, we give examples of the development and application of ontologies in several aeronautic projects. The use of ontologies is described for knowledge representation and retrieval, for indexing and authoring documents, and for building scenarios. The focus of this paper is on domain conceptualization in flight operations, but other topics in the aeronautic domain such as maintenance, human factors, training and organizational processes are also addressed.
