Catalan BERTa-v2 (roberta-base-ca-v2) finetuned for Part-of-speech-tagging (POS)
The roberta-base-ca-v2-cased-pos is a Part-of-speech-tagging (POS) model for the Catalan language fine-tuned from the roberta-base-ca-v2 model, a RoBERTa 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 POS dataset in Catalan from the Universal Dependencies Treebank we refer to Ancora-ca-pos for training and evaluation.
Evaluation and results
We evaluated the roberta-base-ca-v2-cased-pos on the Ancora-ca-ner test set against standard multilingual and monolingual baselines:
| Model | Ancora-ca-pos (F1) |
|---|---|
| roberta-base-ca-v2-cased-pos | 99.09 |
| roberta-base-ca-cased-pos | 99.10 |
| mBERT | 98.98 |
| XLM-RoBERTa | 99.03 |
