Ontology integration: Experiences with medical terminologies

ONIONS is a methodology for ontology analysis and integration. It has been applied to some relevant and very large medical terminologies (e.g. the 332,000 medical concepts singled out by the National Library of Medicine in the UMLS project). Current results include the alignment of the top-level ontologies of the terminologies considered. The paper reviews the formal and conceptual tools employed in this task, presents the most significant results obtained, and discusses two case studies.
