摘　　要：近年来,法类案检索已经成为了法律从业者工作的重要的组成部分。法律类案检索的过程中,搜索引擎从海量的数据中筛选出若干个相关案例,提供给用户。然而,这些案例是否具有性别偏置,该种偏置是否会对用户认知产生影响,却是一个未知数。设计了一个全新的用户实验框架,模拟法官进行类案检索时阅读相关案例的过程。邀请了72位具有法律背景的志愿者进行实验。志愿者被要求模拟法官的身份就指定的3个案例进行类案检索,并对案例中的被告人量刑。对任务和类案检索结果中被告人的性别均进行了编辑,以统计类案检索结果中的性别偏置对被试认知产生的影响。实验结果显示,类案检索结果中的性别偏置对法官的认知不产生显著的影响。In recent years,legal case search has become an important part of a legal practitioner’s work.During legal case search,search engines retrieval a number of relevant cases from huge amounts of data and serve them to users.However,it is uncertain whether these cases are gender-biased and whether such bias has impact on user perceptions.this paper designs a new user experiment framework to simulate the judges’reading of relevant cases.72 participants with backgrounds in legal affairs are invited to conduct the experiment.Participants are asked to simulate the role of the judge in conducting a legal case search on 3 assigned cases and determine the term of the defendants in these cases.Gender of the defendants in both the task and relevant cases is edited to statistically measure the effect of gender bias in the legal case search results on participants’perceptions.The results show that gender bias in the legal case search results has no significant effect on judges’perceptions.
