Model Description

The Biomedical Clinical Language Model for Spanish is based on the RoBERTa architecture, tailored specifically for biomedicine. It has been trained on a vast biomedical-clinical corpus in Spanish collected from diverse sources, ensuring richness and relevance in medical terminology and context.

Intended Uses and Limitations

This model is optimized for masked language modeling, focusing on tasks such as Fill Mask. Although it is ready-to-use for this function, it is designed primarily for fine-tuning on downstream tasks like Named Entity Recognition or Text Classification.

How to Use

Using the model is straightforward. Follow these steps:

1. Install the Transformers library if you haven’t done so yet.
2. Use the following Python snippets:

from transformers import AutoTokenizer, AutoModelForMaskedLM

tokenizer = AutoTokenizer.from_pretrained("BSC-TeMUroberta-base-biomedical-es")
model = AutoModelForMaskedLM.from_pretrained("BSC-TeMUroberta-base-biomedical-es")

from transformers import pipeline

unmasker = pipeline("fill-mask", model="BSC-TeMUroberta-base-biomedical-es")
output = unmasker("El único antecedente personal a reseñar era la  arterial.")
print(output)

3. This simple code initializes the model, and when you run it, it replaces the mask token in the input sentence with the most likely medical term.

Limitations and Bias

The model may possess inherent biases given that the training data comes from multiple sources collected through web crawling. It’s important to apply caution and ensure that any results generated are validated by domain experts.

Training

Training the model involved a variety of data preparation techniques to optimize performance. The training corpus is comprised of over 1 billion tokens, ensuring it captures the nuances of clinical language:

• Data parsing in multiple formats
• Sentence splitting
• Language detection
• Filtering ill-formed sentences
• Document boundary preservation

Think of the training process like preparing for a marathon: It involves assembling a diverse set of training material (like varied routes and terrains) to ensure the model effectively understands and performs in the biomedical landscape.

Evaluation

The model has been rigorously evaluated on Named Entity Recognition tasks using benchmark datasets. It has shown notable results, outperforming previous language models in specific biomedical tasks.

Additional Information

The authorship of this model lies with the Text Mining Unit (TeMU) at the Barcelona Supercomputing Center. It’s important to note that while the models are intended for general use, any deployment should comply with applicable regulations regarding AI usage.
