We present a review of personality in neural conversational agents (CAs),
also called chatbots. First, we define Personality, Persona, and Profile. We
explain all personality schemes which have been used in CAs, and list models
under the scheme(s) which they use. Second we describe 21 datasets which have
been developed in recent CA personality research. Third, we define the methods
used to embody personality in a CA, and review recent models using them.
Fourth, we survey some relevant reviews on CAs, personality, and related
topics. Finally, we draw conclusions and identify some research challenges for
this important emerging field.

综述了神经会话代理（也称为聊天机器人）中的个性特征，包括定义了个性、角色和档案，解释了在会话代理中已经使用的所有个性方案，并列出了使用该方案的模型；描述了在最近的会话代理个性研究中开发的 21 个数据集；定义了在会话代理中体现个性的方法，并回顾了最近使用这些方法的模型；调查了关于会话代理、个性和相关主题的一些相关综述；最后得出结论并确定了这一重要新兴领域的一些研究挑战。
