# MediAlbertina
The first publicly available medical language models trained with real European Portuguese data.

MediAlbertina is a family of encoders from the Bert family, DeBERTaV2-based, resulting from the continuation of the pre-training of [PORTULAN's Albertina](https://huggingface.co/PORTULAN) models with Electronic Medical Records shared by Portugal's largest public hospital.

Like its antecessors, MediAlbertina models are distributed under the [MIT license](https://huggingface.co/portugueseNLP/medialbertina_pt-pt_900m/blob/main/LICENSE).



# Model Description

MediAlbertina PT-PT 900M was created through domain adaptation of [Albertina PT-PT 900M](https://huggingface.co/PORTULAN/albertina-900m-portuguese-ptpt-encoder) on real European Portuguese EMRs by employing masked language modeling. It underwent evaluation through fine-tuning for the Information Extraction (IE) tasks Named Entity Recognition (NER) and Assertion Status (AStatus) on more than 10k manually annotated entities belonging to the following classes: Diagnosis, Symptom, Vital Sign, Result, Medical Procedure, Medication, Dosage, and Progress.
In both tasks, MediAlbertina achieved superior results to its antecessors, demonstrating the effectiveness of this domain adaptation, and its potential for medical AI in Portugal.

| Model                   | NER single-model | NER multi-models | Assertion Status |

|                         |    F1-score      |    F1-score      |    F1-score      |
|albertina-900m-portuguese-ptpt-encoder         |      0.813       |      0.811       |      0.687       |
| **medialbertina_pt-pt_900m** |    **0.832**     |    **0.848**     |    **0.755**     |

## Data

MediAlbertina PT-PT 900M was trained on more than 15M sentences and 300M tokens from 2.6M fully anonymized and unique Electronic Medical Records (EMRs) from Portugal's largest public hospital. This data was acquired under the framework of the [FCT project DSAIPA/AI/0122/2020 AIMHealth-Mobile Applications Based on Artificial Intelligence](https://ciencia.iscte-iul.pt/projects/aplicacoes-moveis-baseadas-em-inteligencia-artificial-para-resposta-de-saude-publica/1567).


## How to use

```Python
from transformers import pipeline

unmasker = pipeline('fill-mask', model='portugueseNLP/medialbertina_pt-pt_900m')
unmasker("Analgesia com morfina em perfusão (15 [MASK]/kg/h)")
```
