Using SNOMED CT with the UMLS - Medical Ontology Research

Mapping terms to a terminology
• Generally, it works like this:
◦ Find a match the incoming term against all
terms in the UMLS
◦ Normalization will increase yield
◦ Synonymous word/phrase substitution
◦ Ranking of degree of match
◦ Restrict the match to UMLS concepts
containing terms from the target terminology
