Model description

This is a Transformer's SetFit model trained for biomedical text pairs classification in Spanish.

Intended uses and limitations

The model is prepared to classify hierarchical relations among medical terms. This includes the following types of relations: BROAD, EXACT, NARROW, NO_RELATION.

How to use

This model is implemented as part of the KeyCARE library. Install first the keycare module to call the SetFit classifier:

python -m pip install keycare

You can then run the KeyCARE pipeline that uses the SetFit model:

from keycare install RelExtractor.RelExtractor

# initialize the termextractor object
relextractor = RelExtractor(relation_method='setfit')
# Run the pipeline
source = ["cáncer", "enfermedad de pulmón", "mastectomía radical izquierda", "laparoscopia"]
target = ["cáncer de mama", "enfermedad pulmonar", "mastectomía", "Streptococus pneumoniae"]
relextractor(source, target)
# You can also access the class storing the SetFit model
relator = relextractor.relation_method

Training

The model has been trained using an efficient few-shot learning technique that involves:

1. Fine-tuning a Sentence Transformer with contrastive learning. The used pre-trained model is SapBERT-from-roberta-base-biomedical-clinical-es from the BSC-NLP4BIA reserch group.
2. Training a classification head with features from the fine-tuned Sentence Transformer.

The training data has been obtained using the hirerarchical structure of SNOMED-CT mapped to the medical terms present in UMLS.
