# Catalan RoBERTa-base (BERTa) finetuned for Question Answering on the viquiquad dataset.

The **roberta-base-ca-cased-qa** is a Question Answering (QA) model for the Catalan language fine-tuned from the [BERTa](https://huggingface.co/PlanTL-GOB-ES/roberta-base-ca) model, a [RoBERTa](https://arxiv.org/abs/1907.11692) base model pre-trained on a medium-size corpus collected from publicly available corpora and crawlers (check the BERTa model card for more details).

## Datasets
We used the QA dataset in Catalan called [ViquiQuAD](https://huggingface.co/datasets/projecte-aina/viquiquad) for training and evaluation, and the [XQuAD-ca](https://huggingface.co/datasets/projecte-aina/xquad-ca) test set for evaluation.

## Evaluation and results

| Task        | QA (ViquiQuAD) (F1/EM)  | QA (XQuAD-ca) (F1/EM) | 
| ------------|:------|:----|
| BERTa       | **86.99/73.25** | **67.81/49.43** |
