Description: Unified Medical Language System is a set of files and software that brings together many health and biomedical vocabularies and standards to enable interoperability between computer systems. The UMLS integrates and distributes key terminology, classification and coding standards, and associated resources to promote creation of more effective and interoperable biomedical information systems and services, including electronic health records.

UMLS includes three UMLS Knowledge Sources:

  • Metathesaurus: Terms and codes from many vocabularies, including CPT, ICD-10-CM, LOINC, MeSH, RxNorm, and SNOMED CT. Hierarchies, definitions, and other relationships and attributes.
  • Semantic Network: Broad categories (semantic types) and their relationships (semantic relations).
  • SPECIALIST Lexicon and Lexical Tools: A large syntactic lexicon of biomedical and general English and tools for normalizing strings, generating lexical variants, and creating indexes.
