Installing NCI Vocabularies in LexEVS 6.x

The NCI Thesaurus differs from other OWL formatted resources and as a result you should follow this documentation.
The NCI Metathesaurus is the largest terminology to be loaded and as such it also requires special handling.

Installing OWL Formatted terminologies

OWL terminologies do not normally require special handling, but LexEVS offers some advanced loading options users may take advantage of.

Installing Vocabularies from the UMLS Metathesaurus (RRF)

Terminologies in RRF format typically come from the National Library of Medicine's (NLM) Unified Medical Language System (UMLS). Many terminologies are a subset of the UMLS such as LOINC, SNOMED, MedDRA, HUGO, GO, and ICD to name a few. The terminology you're interested in is a subset of the UMLS if:

• The terminology is documented by the NLM as a source for the UMLS or
• The "Download" column on the Vocabulary Knowledge Center's Index of Terminologies includes RRF or
• The FORMAT type listed in BioPortal is RRF.

None of the above match and you cannot find a suitable source format.

Many terminology providers produce more than one source format that can be downloaded. Source formats such as text only, CSV, tab delimited, and spreadsheets are not acceptable source formats for LexEVS. If you can not find an acceptable source format for a terminology to load into LexEVS then one option is to download versions that have been placed on BioPortal. These may not be the latest versions available but are easy to download. If you end up with a with a terminology that is not one of the special cases above then you should return to the generic loading instructions.
