Description
This model maps clinical entities to UMLS CUI codes. It is trained on 2021AB UMLS dataset. The complete dataset has 127 different categories, and this model is trained on the Clinical Drug category using sbiobert_base_cased_mli embeddings.
Predicted Entities
Predicts UMLS codes for Clinical Drug medical concepts
How to use
sbiobertresolve_umls_clinical_drugs resolver model must be used with sbiobert_base_cased_mli as embeddings ner_posology as NER model. DRUG set in .setWhiteList().
