Early ontological engineering methodologies have necessarily focussed on the management of the whole ontology development process. There is a corresponding need to provide advice to the ontological engineer on the ®ner details of ontology construction. Here, we speci®cally address the representation of hierarchical relationships in an ontology. We identify ®ve types of problem that may be encountered in moving from an informal description of a domain to a formal representation of hierarchical knowledge. Each problem type is discussed from the perspective of knowledge sharing and examples from biological ontologies are used to illustrate each type. Ó 1999 Elsevier Science B.V. All rights reserved.
