Title
¬The representation of meaning in the UMLS

Abstract
The Unified Medical Language System knowledge source provide detailed information about biomedical naming systems and databases. The Metathesaurus contains biomedical terminology from an increasing number of biomedical thesauri, and the Semantic Netowrk provides a structure that encompasses and unifies the thesauri that are included in the Metathesaurus. Addresses some fundamental principles underlying the design and development of the Metathesaurus and Semantic Network. Describes the formal properties of the semantic network. Considers the principle of semantic locality and how this is reflected in the UMLS knowledge sources. Discusses the issues involved in attempting to reuse knowledge and the potential for reuse of the UMLS knowledge sources
