Description
A pipeline for detecting posology entities with the ner_posology_large NER model, assigning their assertion status with assertion_jsl model, and extracting relations between posology-related terminology with posology_re relation extraction model.
Predicted Entities
DRUG, DOSAGE, DURATION, FORM, FREQUENCY, ROUTE, STRENGTH
How to use
