摘要:

法律判决预测(Legal Judgment Prediction,LJP)是在给定描述案件事实的文本的情况下,自动预测案件判决结果的任务,在司法协助系统中具有良好的应用前景,为公众提供便捷的服务。在实践中,混淆罪名的情况时有发生,因为适用相似法条的案件容易发生误判。现有的方法在解决这一问题时严重依赖于领域专家,这阻碍了其在不同法系的适用。在本文中,我们提出了一个端到端的模型,LADAN,解决LJP的任务。为了区分易混淆的指控,我们提出了一种新的图神经网络,自动学习混淆法律文章之间的细微差异,并设计了一种新的注意力机制,充分利用学习到的差异,从事实描述中提取引人注目的区别特征。在真实数据集上进行的实验证明了我们的LADAN的优越性。

英文摘要:

Legal Judgment Prediction (LJP) is the task of automatically predicting a law case's judgment results given a text describing its facts, which has excellent prospects in judicial assistance systems and convenient services for the public. In practice, confusing charges are frequent, because law cases applicable to similar law articles are easily misjudged. For addressing this issue, the existing method relies heavily on domain experts, which hinders its application in different law systems. In this paper, we present an end-to-end model, LADAN, to solve the task of LJP. To distinguish confusing charges, we propose a novel graph neural network to automatically learn subtle differences between confusing law articles and design a novel attention mechanism that fully exploits the learned differences to extract compelling discriminative features from fact descriptions attentively. Experiments conducted on real-world datasets demonstrate the superiority of our LADAN.
