## Model description
A fine-tuned version of [BSC-LT/MrBERT-biomed](https://huggingface.co/BSC-LT/MrBERT-biomed) for **PROCEDURE Named Entity Recognition** in Spanish clinical text. It was developed for MultiClinNER, a subtask of the [MultiClinAI shared task](https://temu.bsc.es/MultiClinAI/) organized by the NLP4BIA team at the Barcelona Supercomputing Center as part of the #SMM4H-HeaRD Workshop at the ACL 2026 conference. The model labels mentions of **PROCEDURE** using the BIO tagging scheme: `O`, `B-PROCEDURE`, `I-PROCEDURE`.

## 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.

```python
from transformers import pipeline

ner = pipeline(
    "token-classification",
    model="BSC-NLP4BIA/multiclinner-es-procedure-MrBERT-biomed",
    aggregation_strategy="simple",
)
ner("...clinical text in Spanish...")
```

## Evaluation

Scores were computed with the official [MultiClinAIEval](https://github.com/nlp4bia-bsc/MultiClinAIEval) library on the MultiClinNER **Spanish** gold-standard test documents for **PROCEDURE** (the shared-task gold set for this language and entity type).

| Metric | Score | Definition |
|---|---|---|
| strict F1 | 0.641 | exact match of both entity span (start/end) and label |
| char F1 (gold) | 0.744 | character-level F1, restricted to the gold-standard documents |

See the [MultiClinAI shared task](https://temu.bsc.es/MultiClinAI/) for the full evaluation protocol.

## 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. We intend to conduct research in these areas in the future, and if completed, this model card will be updated.
