What is the main idea of the Unified Medical Language System UMLS?
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.
Is UMLS an ontology?
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.
What standards do UMLS support?
NLM supports, licenses, or develops key Clinical Vocabularies identified for Meaningful Use and HIPAA transactions: SNOMED CT®, LOINC®, and RxNorm. NLM provides uniform distribution for more than 150 clinical vocabulary standards and HIPAA administrative code sets through the UMLS Metathesaurus.
What is the UMLS Metathesaurus?

What is a CUI UMLS?
CUI – The Concept Unique Identifier for a Metathesaurus concept to which strings with the same meaning are linked. One of the principles of the Metathesaurus is that meanings should be preserved over time regardless of what terms (atoms) are used to express those meanings.
How is UMLS associated with snomed?
In SNOMED CT the RelationshipType field contains a ConceptId pointing to a linkage concept in the ‘Attribute’ hierarchy. In UMLS, the RELA field stores directly the name of the linkage concept (e.g. ‘is a’) instead of its ConceptId (‘116680003’) to enhance readability.
How does SNOMED CT work?
