## Model description
A fine-tuned version of the [bsc-bio-ehr-es](https://huggingface.co/PlanTL-GOB-ES/bsc-bio-ehr-es) model on the [MEDDOCAN](https://zenodo.org/records/4279323) corpus.

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

## Intended uses and limitations

TDB

## How to use

⚠ We recommend pre-tokenizing the input text into words instead of providing it directly to the model, as this is how the model was trained. Otherwise, the results and performance might get affected.

A usage example can be found [here](https://github.com/nlp4bia-bsc/hugging-face-pipeline/blob/main/simple_inference.ipynb).

## 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. 

## Training
The model was trained using the Barcelona Supercomputing Center infrastructure.

## Evaluation 
F1 Score: 0.961 on MEDDOCAN

F1 Score: 0.811 on CARMEN-I Anonymization
