• liaad/srl-pt_xlmr-base
• liaad/srl-pt_xlmr-large
• liaad/srl-pt_mbert-base
• liaad/srl-en_xlmr-base
• liaad/srl-en_xlmr-large
• liaad/srl-en_mbert-base
• liaad/srl-enpt_xlmr-base
• liaad/srl-enpt_xlmr-large
• liaad/srl-enpt_mbert-base

Intended uses & limitations

How to use

To use the transformers portion of this model:

from transformers import AutoTokenizer, AutoModel

tokenizer = AutoTokenizer.from_pretrained("liaad/srl-pt_bertimbau-base")
model = AutoModel.from_pretrained("liaad/srl-pt_bertimbau-base")

To use the full SRL model (transformers portion + a decoding layer), refer to the project's github.

Training procedure

The model was trained on the PropBank.Br datasets, using 10-fold Cross-Validation. The 10 resulting models were tested on the folds as well as on a smaller opinion dataset "Buscapé". For more information, please see the accompanying article (See BibTeX entry and citation info below) and the project's github.
