Abstract: With the improvement of people’s awareness of law and the continuous advancement of judicial digital reform, judicial organs and some corresponding platforms have accumulated a large amount of legal data. On this basis, it is critical to research and develop an intelligent system for legal domain using artificial intelligence algorithm, which cannot only assist legal practitioners in processing large amounts of data, but also provide convenient and cheap legal consultation services to the general public. This paper summarizes the topic of intelligent systems for legal domain, and selects four typical tasks for the research of legal intelligent system according to different application scenarios, which are judicial examination, civil legal question answering, judicial machine reading comprehension and legal judgment prediction. The paper introduces the definition, relevant datasets and evaluation indicators of each type of task in detail. Then, it analyzes the key points and difficulties involved in each type of task, and summarizes reasonable and effective solutions proposed by different research teams for these problems. Based on the comparison and analysis of the latest research progress, it further explores and reveals the main factors restricting the development of legal intelligence system. Finally, it prospects the future development trend of legal intelligent system.

Key words: artificial intelligence, legal question answering, judicial examination, machine reading comprehension, legal judgment prediction

摘要: 随着人们法治意识的提高以及司法数字化改革的不断推进,司法机关和一些相应的平台都已经积累了大量的法律数据。在此基础上,借助人工智能算法研究和开发面向司法领域的智能系统具有重要的现实意义,它一方面可以协助法律从业人员分析处理海量数据,另一方面还能为普通民众提供便捷廉价的法律咨询服务等。以面向法律领域的智能系统为主题进行综述,根据不同应用场景选取了面向法律领域的智能系统研究的四个典型任务,分别是司法考试、民用法律问答、司法机器阅读理解、法律判决预测。详细介绍了每类任务的定义、相关数据集以及评价指标;对每类任务涉及到的重点和难点问题进行逐一剖析,并针对这些问题归纳出不同研究团队提出的合理有效的解决方案。在对最新的研究进展进行对比与分析的基础上,进一步探讨和揭示制约法律智能系统发展的主要因素;最后,对面向法律领域的智能系统研究的未来发展态势进行了展望。
