Abstract:
Abstract. Ontologies provide explicit models of shared conceptualizations, and are useful for modeling formal, semi-formal, and informal knowledge needed for communication within a company. As there is typically more than one ontology used in a company (for instance one in each department), techniques are needed to merge ontologies in order to assure cross-company communication. In this paper, we summarize one such approach, called FCA{Merge. During its development, it turned out that a formal denition of `ontology ' is needed. The resulting denition is presented for the rst time in detail in this paper. 1
