We introduce the Cambridge Law Corpus (CLC), a corpus for legal AI research.
It consists of over 250 000 court cases from the UK. Most cases are from the
21st century, but the corpus includes cases as old as the 16th century. This
paper presents the first release of the corpus, containing the raw text and
meta-data. Together with the corpus, we provide annotations on case outcomes
for 638 cases, done by legal experts. Using our annotated data, we have trained
and evaluated case outcome extraction with GPT-3, GPT-4 and RoBERTa models to
provide benchmarks. We include an extensive legal and ethical discussion to
address the potentially sensitive nature of this material. As a consequence,
the corpus will only be released for research purposes under certain
restrictions.

介绍了剑桥法律语料库（CLC），这是一个用于法律人工智能研究的语料库。该语料库包括超过 25 万个来自英国的法庭判例，涵盖了从 16 世纪至 21 世纪的案件。该论文介绍了该语料库的第一个版本，并提供 638 个案例的案件结果注释，以作为使用 GPT-3、GPT-4 和 RoBERTa 模型进行案件结果提取的基准。该论文还包括了广泛的法律和伦理讨论，以解决这一材料可能具有的敏感性。因此，该语料库仅在特定限制下释放供研究目的使用。
