# Catalan BERTa-v2 (roberta-base-ca-v2) finetuned for Textual Entailment.

The **roberta-base-ca-v2-cased-te** is a Textual Entailment (TE) model for the Catalan language fine-tuned from the [roberta-base-ca-v2](https://huggingface.co/projecte-aina/roberta-base-ca-v2) 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 roberta-base-ca-v2 model card for more details).

## Datasets
We used the TE dataset in Catalan called [TECA](https://huggingface.co/datasets/projecte-aina/teca) for training and evaluation.

## Evaluation and results
We evaluated the roberta-base-ca-cased-te on the TECA test set against standard multilingual and monolingual baselines:

| Model        | TECA (Accuracy) | 
| ------------|:----|
| roberta-base-ca-v2-cased-te | **83.14** |
| BERTa       | 79.26 |
| mBERT       | 74.63 |
| XLM-RoBERTa | 33.30 |

For more details, check the fine-tuning and evaluation scripts in the official [GitHub repository](https://github.com/projecte-aina/club).
