Catalan BERTa (RoBERTa-base) finetuned for Semantic Textual Similarity.

The roberta-base-ca-cased-sts is a Semantic Textual Similarity (STS) model for the Catalan language fine-tuned from the BERTa model, a RoBERTa 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 TE dataset in Catalan called STS-ca for training and evaluation.

Evaluation and results

We evaluated the roberta-base-ca-cased-sts on the STS-ca test set against standard multilingual and monolingual baselines:

Model	STS-ca (Pearson)
roberta-base-ca-cased-sts	81.20
mBERT	76.34
XLM-RoBERTa	75.40
WikiBERT-ca	77.18

For more details, check the fine-tuning and evaluation scripts in the official GitHub repository.
