CAIL2019-相似案例匹配

任务介绍

本任务是针对多篇法律文书进行相似度的计算和判断。具体来说,对于提供的每份文书事实描述,从两篇候选集文书中找到与询问文书更为相似的一篇文书。 该相似案例匹配的数据只涉及民间借贷这类文书。

数据介绍

本任务使用的数据集是来自“**裁判文书网”公开的法律文本,其中每份数据由三篇法律文本组成。数据总共涉及一万组文书三元对,所有的文书三元组对都一定属于民间借贷案由。对于每篇法律文本,提供该文书的事实描述部分。具体地,文件的每一行对应一组数据,且每行的格式都为一个json数据。

对于每份数据,用(A,B,C)来代表改组数据,其中(A,B,C)均对应某一篇文书。在训练数据中,文书数据A与B的相似度是大于A与C的相似度,即sim(A,B)>sim(A,C)。
