- UMLS
- The Unified Medical Language System (UMLS) system is a large project sponsored by the United States National Library of Medicine (NLM) to produce a unified thesaurus and cross reference linking various medical nomenclatures including the MeSH headings, ICD-9-CM, SNOMED and the terminologies of DXPlain and QMR. One of the main outputs of the UMLS project is the Meta-1 Metathesaurus. The Unified Medical Language System (UMLS) has three components: an Information Sources Directory, a Metathesaurus and a Semantic Net. The Information Sources Directory contains information about publicly available biomedical information resources. For each source the Directory contains the sources scope, vocabulary, syntax, rules and access conditions. The Metathesaurus contains concepts from a variety of biomedical vocabularies. Each concept has a canonical representation that includes a semantic type. Mappings between different vocabularies are handled by this canonical representation. The Semantic Net represents relationships among the semantic types.
