CUI (Concept unique identifier)

What is CUI?

In the Unified Medical Language System (UMLS) of the National Library of Medicine (NLM) the concept unique identifier (CUI) is an 8-character identifier beginning with the letter "C" and followed by 7 digits. Each concept is assigned such a CUI. The CUI has no intrinsic meaning but remains constant through time and across versions. (NCI Thesaurus)

What is CUI2Vec

Cui2Vec is a new set of embeddings for medical concepts learned using an extremely large collection of multimodal medical data. See this paper.

How does Hephaestus use CUI2Vec

Hephaestus uses Cui2Vec for various concept similarity searches, by mapping OMOP CDM concepts to CUIs and back.

• Create tables using instructions here: https://github.com/E-Health/OHDSIconceptid2cui
• Cui.init_model() downloads and builds Cui2Vec model.
• Find similar concepts, outliers and calculate distances.
• Cui2Vec for noisy labeling and anchor learning.
