Abstract

Psychology and cognitive science show that human concepts possess particular structures (conceptual structures). However, in the process of ontology modeling information concerning the structure of human concepts is lost. In ontologies concepts are typically represented as undifferentiated collections of necessary (or necessary and sufficient) conditions. The lack of representation of conceptual structure may cause ontologies to be inadequate and may limit their usability for human users. We present an attempt to bring ontology modeling closer to theories of conceptual structures, in particular to psychological essentialism. A metaontology is developed to support the representation of conceptual structure, in particular the distinction between essential and merely necessary conditions.
