AI总结:

本文提出法律事实预测(LFP)任务,以诉讼证据为输入预测法律事实,弥补法律判决预测在缺乏真实法律事实时无法应用的不足,并构建首个基准数据集LFPBench验证其有效性。

摘要:

法律判决预测(LJP)使诉讼当事人及其律师能够预测判决结果并优化诉讼策略,已成为一项重要的法律自然语言处理(NLP)任务。现有研究通常利用法律事实,即已经由证据确立并由法官认定的事实,来预测判决。然而,法律事实在诉讼早期往往难以获得,这极大地限制了基于事实的LJP的实际适用性。为了解决这一局限,我们提出了一项新颖的法律NLP任务:法律事实预测(LFP),该任务以诉讼当事人提交审判的证据作为输入来预测法律事实,从而使基于事实的LJP技术能够在缺乏真实法律事实的情况下进行预测。我们还提出了第一个用于评估LFP任务的基准数据集LFPBench。我们在LFPBench上进行的大量实验证明了LFP赋能的LJP的有效性,并突出了LFP有前景的研究方向。

英文摘要:

Legal judgment prediction (LJP), which enables litigants and their lawyers to forecast judgment outcomes and refine litigation strategies, has emerged as a crucial legal NLP task. Existing studies typically utilize legal facts, i.e., facts that have been established by evidence and determined by the judge, to predict the judgment. However, legal facts are often difficult to obtain in the early stages of litigation, significantly limiting the practical applicability of fact-based LJP. To address this limitation, we propose a novel legal NLP task: legal fact prediction (LFP), which takes the evidence submitted by litigants for trial as input to predict legal facts, thereby empowering fact-based LJP technologies to make predictions in the absence of ground-truth legal facts. We also propose the first benchmark dataset, LFPBench, for evaluating the LFP task. Our extensive experiments on LFPBench demonstrate the effectiveness of LFP-empowered LJP and highlight promising research directions for LFP.
