模型:
nlpaueb/bert-base-uncased-eurlex
LEGAL-BERT是用于法律领域的BERT模型系列,旨在辅助法律NLP研究、计算法律和法律技术应用。为了预训练不同的LEGAL-BERT变体,我们从公开资源中收集了12 GB的不同领域(例如立法、法院案例、合同)的英文法律文本。子域变体(CONTRACTS-、EURLEX-、ECHR-)和/或一般LEGAL-BERT在特定领域的任务中表现更好,优于直接使用BERT。这是在欧盟立法上预训练的子域变体。
I. Chalkidis, M. Fergadiotis, P. Malakasiotis, N. Aletras和I. Androutsopoulos。“LEGAL-BERT:来自法学院的木偶”。在Empirical Methods in Natural Language Processing(EMNLP 2020)(短文)的发现中,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 )的116,062个欧盟立法文档,公开可用于欧盟出版社的EU法令库。
来自英国立法门户网站( http://www.legislation.gov.uk )的61,826个英国立法文档,公开可用。
来自EURLEX的19,867个欧洲法院(European Court of Justice,ECJ)案例。
来自欧洲人权法院(European Court of Human Rights,ECHR)数据库HUDOC的12,554个案例( http://hudoc.echr.coe.int/eng )。
来自美国各个法院的164,141个案例,托管在Case Law Access Project门户网站上( https://case.law )。
来自美国证券交易委员会(US Securities and Exchange Commission,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)中称为LEGAL-BERT-SC的模型;它是在下面提到的法律语料库上使用由句子分割标记器在相同语料库上进行训练的新词汇表从头训练的模型。
**由于许多人对LEGAL-BERT-FP模型(基于原始BERT-BASE检查点的模型)表示兴趣,它们已在Archive.org上发布( https://archive.org/details/legal_bert_fp ),因为这些模型是辅助模型,可能仅对那些想深入探讨Chalkidis等人(2020)的开放问题的人有兴趣。
