Legalnlp Bert

🚀 BERTikal（又名 legalnlp-bert）

BERTikal [1] 是一个针对巴西法律语言的大小写敏感的BERT基础模型，它基于BERTimbau [2] 的检查点，使用巴西法律文本进行训练。关于数据集和训练过程的更多细节可在 [1] 中找到。

🚀 快速开始

BERTikal 是专门为巴西法律语言设计的BERT模型，可用于法律文本的自然语言处理任务，如特征提取、掩码语言建模预测等。

💻 使用示例

基础用法

示例：加载通用模型

from transformers import AutoTokenizer  # Or BertTokenizer
from transformers import AutoModelForPreTraining  # Or BertForPreTraining for loading pretraining heads
from transformers import AutoModel  # or BertModel, for BERT without pretraining heads

model = AutoModelForPreTraining.from_pretrained('felipemaiapolo/legalnlp-bert')
tokenizer = AutoTokenizer.from_pretrained('felipemaiapolo/legalnlp-bert', do_lower_case=False)

示例：获取BERT嵌入

from transformers import pipeline

pipe = pipeline("feature-extraction", model='felipemaiapolo/legalnlp-bert')
encoded_sentence = pipe('Juíz negou o recurso.')

高级用法

示例：掩码语言建模预测

from transformers import pipeline

pipe = pipeline('fill-mask', model='felipemaiapolo/legalnlp-bert')

pipe('Juíz negou o [MASK].')
#  [{'score': 0.6387444734573364,
#  'token': 7608,
#  'token_str': 'julgamento',
#  'sequence': 'juiz negou o julgamento.'},
# {'score': 0.09632532298564911,
#  'token': 7509,
#  'token_str': 'voto',
#  'sequence': 'juiz negou o voto.'},
# {'score': 0.06424401700496674,
#  'token': 17225,

#  'token': 6330,
#  'token_str': 'registro',
#  'sequence': 'juiz negou o registro.'}]
