中文(BERT base) Language modeling in the legal domain in Portuguese
legal-bert-base-cased-ptbr is a Language Model in the legal domain in Portuguese based on the model BERTimbau base by using a MASK objective.
The model is intended to assist NLP research in the legal field, computer law and legal technology applications. Several legal texts in Portuguese were used (more information below).
Large version of the model will be available soon .
Pre-training corpora
The pre-training corpora of legal-bert-base-cased-ptbr include:
- 61309 - Documentos juridicos diversos | (Miscellaneous legal documents)
- 751 - Petições (Recurso Extraordinário JEC) | (Petitions)
- 682 - Sentenças | (Sentences)
- 498 - Acordãos 2º Instancia | (2nd Instance Accords)
- 469 - Agravos Recurso extraordinário | (RE grievances)
- 411 - Despacho de Admissibilidade | (Admissibility Order)
The data used was provided by the BRAZILIAN SUPREME FEDERAL TRIBUNAL, through the terms of use: LREC 2020 .
The results of this project do not imply in any way the position of the BRAZILIAN SUPREME FEDERAL TRIBUNAL, all being the sole and exclusive responsibility of the author of the model.
