## Model description

This is a [SetFit model](https://github.com/huggingface/setfit) that can be used for text classification. The model has been trained using an efficient few-shot learning technique that involves:

1. Fine-tuning [BSC-NLP4BIA/SapBERT-from-roberta-base-biomedical-clinical-es](https://huggingface.co/BSC-NLP4BIA/SapBERT-from-roberta-base-biomedical-clinical-es) with contrastive learning using the [MEDDOPLACE](https://doi.org/10.5281/zenodo.7707566) corpus (subtrack 3) for subcategorization of location entities.
2. Training a classification head with features from the fine-tuned Sentence Transformer.

The labels for which this model has been trained are: brith place (LUGAR_NATAL), residence (RESIDENCIA), movement (MOVIMIENTO), medical care (ATENCION), and other (OTHER).

For further information, check the [official website](https://temu.bsc.es/meddoplace/).

## How to use

To use this model for inference, first install the SetFit library:

```bash
python -m pip install setfit
```

You can then run inference as follows:

```python
from setfit import SetFitModel

# Download from Hub and run inference
model = SetFitModel.from_pretrained("BSC-NLP4BIA/location-sub-classifier")
# Run inference
preds = model(["example1", "example2"])
```

## Limitations and bias
At the time of submission, no measures have been taken to estimate the bias embedded in the model. However, we are well aware that our models may be biased since the corpora have been collected using crawling techniques on multiple web sources. We intend to conduct research in these areas in the future, and if completed, this model card will be updated. 

## Evaluation
A classification report has been generated for the MEDDOPLACE subtask3, which yields the following results:
| Category       | Precision | Recall | F1-Score |
|----------------|-----------|--------|----------|
| ATENCION       | 0.87      | 0.88   | 0.88     |
| LUGAR-NATAL    | 0.72      | 0.79   | 0.75     |
| MOVIMIENTO     | 0.82      | 0.75   | 0.78     |
| OTHER          | 0.86      | 0.83   | 0.85     |
| RESIDENCIA     | 0.78      | 0.84   | 0.81     |
| **accuracy**   | **0.83**  |        |          |
| **macro avg**  | 0.81      | 0.82   | 0.81     |
| **micro avg**  | 0.84      | 0.83   | 0.84     |
