摘要

针对智慧司法服务领域中“法律判决预测”任务的实际需求，探讨了法律判决预测任务的研究思路与实现路径，介绍了法律判决预测的整体框架和具体过程。基于从中国裁判文书网获取的海量真实案件数据和2018“中国法研杯”司法人工智能挑战赛的评测数据，整理了实验数据类别，规范了实验数据格式，形成了基于法律裁判文书大数据的法律判决预测数据集。在判决预测模型中，首先使用判决要素抽取方法提取出高质量的判决要素句，然后借鉴法官的判案思路，将整个法律判决预测任务转换为法条预测、罪名预测和刑期预测3项子任务，并分别构建了基于判决要素的预测模型。实验结果表明，所提方法在刑法类判决预测数据集上得到了有效的结果。

Abstract

According to the actual needs of the task of “legal judgment prediction” in the field of intelligent judicial services

the research ideas and implementation ways were discussed

and the overall framework and the specific process of this task were introduced.Based on the massive real cases obtained by China Judgments Online and the evaluation dataset of CAIL2018

the categories were sorted out.The format of the experimental dataset was standardized.And the prediction dataset of legal judgment prediction based on legal judgment documents was built.For the judgment prediction model

the high-quality sentences by using the method of decision elements extraction were extracted.Then refer to the judge’s judgment ideas

the whole task of legal judgment prediction was transform into three subtasks

namely the law articles prediction

the charge prediction

and the penalty prediction.Meanwhile

construct the prediction models based on the judgment elements respectively.The experimental results show that the proposed methods achieves excellent results on the criminal law judgment prediction dataset.
