Circular hierarchical relationships in the UMLS: etiology, diagnosis, treatment, complications and prevention.

Year: 2001

Type: conference-paper

Abstract: The Unified Medical Language System (UMLS) is a large repository of some 800,000 concepts for the biomedical domain, organized by several millions of inter-concept relationships, either inherited from the source vocabularies, or specifically generated. This paper focuses on hierarchical relationships in the UMLS Metathesaurus, and especially, on circular hierarchical relationships. Using the metaphor of a disease, we first analyze the causal mechanisms for circular hierarchical relationships. Then, we discuss methods to identify and remove these relationships. Finally, we briefly discuss the consequences of these relationships for applications based on the UMLS, and we propose some prevention measures.
