模型:
nlpaueb/bert-base-uncased-contracts
LEGAL-BERT是用于法律领域的BERT模型系列,旨在辅助法律自然语言处理研究、计算法律和法律科技应用。为了预训练不同变体的LEGAL-BERT,我们从公开可用资源中收集了来自多个领域(包括立法、法庭案例和合同)的12GB多样化的英文法律文本。子领域变体(CONTRACTS-、EURLEX-、ECHR-)和/或通用的LEGAL-BERT在特定领域的任务上表现比直接使用BERT更好。这是在美国合同上预训练的子领域变体。
I. Chalkidis, M. Fergadiotis, P. Malakasiotis, N. Aletras和I. Androutsopoulos. "LEGAL-BERT:脱离法学院的木偶"。在Empirical Methods in Natural Language Processing (EMNLP 2020) (Short Papers)上发表,将在线举行,2020年。( https://aclanthology.org/2020.findings-emnlp.261 )
LEGAL-BERT的预训练语料库包括:
来自EURLEX( http://eur-lex.europa.eu )公开可用的欧盟立法文件116,062份,这是在欧盟出版办公室运行的EU法律存储库。
来自英国立法门户网站( http://www.legislation.gov.uk )公开可用的61,826份英国立法文件。
来自欧洲法院(ECJ)的19,867个案件,也可从EURLEX获得。
来自欧洲人权法院(ECHR)存储库HUDOC的12,554个案件( http://hudoc.echr.coe.int/eng )。
来自美国不同法院的164,141个案例,托管在Case Law Access Project门户网站中( https://case.law )。
来自美国证券交易委员会(SECOM)数据库EDGAR的76,366个美国合同( https://www.sec.gov/edgar.shtml )。

* LEGAL-BERT-BASE是Chalkidis等人(2020)中提到的LEGAL-BERT-SC模型;该模型是根据下面提到的法律语料库从头开始训练的模型,使用相同语料库训练的句子分隔符分词器创建了一个新的词汇表。
** 由于许多人对LEGAL-BERT-FP模型(依赖于原始BERT-BASE检查点)表示了兴趣,它们已在Archive.org( https://archive.org/details/legal_bert_fp )上发布,因为这些模型是次要的,并且可能只对那些有意深入研究Chalkidis等人(2020)中的问题的人有趣。
