- The Unified Medical Language System (UMLS) is a compendium of many controlled vocabularies in the biomedical sciences (created 1986[1]). It provides a mapping structure among these vocabularies and thus allows one to translate among the various terminology systems; it may also be viewed as a comprehensive thesaurus and ontology of biomedical concepts. UMLS further provides facilities for natural language processing. It is intended to be used mainly by developers of systems in medical informatics.
UMLS consists of Knowledge Sources (databases) and a set of software tools.
The UMLS was designed and is maintained by the US National Library of Medicine, is updated quarterly and may be used for free. The project was initiated in 1986 by Donald A. B. Lindberg, M.D., then and current Director of the Library of Medicine.

- The UMLS, or 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.
You can use the UMLS to enhance or develop applications, such as electronic health records, classification tools, dictionaries and language translators.

- The UMLS has three tools, which we call the Knowledge Sources:
- Metathesaurus: Terms and codes from many vocabularies, including CPT®, ICD-10-CM, LOINC®, MeSH®, RxNorm, and SNOMED CT®
- Semantic Network: Broad categories (semantic types) and their relationships (semantic relations)
- SPECIALIST Lexicon and Lexical Tools: Natural language processing tools
- We use the Semantic Network and Lexical Tools to produce the Metathesaurus. Metathesaurus production involves:
- Processing the terms and codes using the Lexical Tools
- Grouping synonymous terms into concepts
- Categorizing concepts by semantic types from the Semantic Network
- Incorporating relationships and attributes provided by vocabularies
- Releasing the data in a common format
- Although we integrate these tools for Metathesaurus production, you can access them separately or in any combination according to your needs.
