## Model description
This is a Transformer's [AutoModelForSequenceClassification](https://huggingface.co/docs/transformers/model_doc/auto#transformers.AutoModelForSequenceClassification) trained for multilabel biomedical text classification in Spanish.
## Intended uses and limitations
The model is prepared to classify medical entities among 21 classes, including diseases, medical procedures, symptoms, and drugs, among others. It still lacks some classes like body structures.
## How to use
This model is implemented as part of the KeyCARE library. Install first the keycare module to call the Transformer classifier:
```bash
python -m pip install keycare
```
You can then run the KeyCARE pipeline that uses the SetFit model:
```python
from keycare install TermExtractor.TermExtractor
# initialize the termextractor object
termextractor = TermExtractor(categorization_method='transformers')
# Run the pipeline
text = """Acude al Servicio de Urgencias por cefalea frontoparietal derecha.
Mediante biopsia se diagnostica adenocarcinoma de pr贸stata Gleason 4+4=8 con met谩stasis 贸seas m煤ltiples.
Se trata con 脕cido Zoledr贸nico 4 mg iv/4 semanas.
"""
termextractor(text)
# You can also access the class storing the Transformer model
categorizer = termextractor.categorizer
```
## Training
The used pre-trained model is SapBERT-from-roberta-base-biomedical-clinical-es from the BSC-NLP4BIA reserch group. The model has been trained using data obtained from NER Gold Standard Corpora also generated by BSC-NLP4BIA, including [MedProcNER](https://temu.bsc.es/medprocner/), [DISTEMIST](https://temu.bsc.es/distemist/), [SympTEMIST](https://temu.bsc.es/symptemist/), [CANTEMIST](https://temu.bsc.es/cantemist/), and [PharmaCoNER](https://temu.bsc.es/pharmaconer/), among others.
