为了能够表现出广泛的合作行为，基于计算机的对话系统必须具备有关当前用户的目标、计划、背景知识以及（错误的）信念的假设，即维持一个所谓的“用户模型”。除了合作方面的因素，这样一个模型对于一般的智能连贯对话行为也是必要的。本文综述了近期关于在系统与用户交互过程中如何构建、表示和使用这样一个模型的问题的研究。然后讨论了可能的应用以及与应用的可取性相关的潜在问题。最后，提出了一些在未来研究中应遵循的指导方针，以降低用户建模技术被潜在误用的风险。
In order to be capable of exhibiting a wide range of cooperative behavior, a computer-based dialog system must have available assumptions about the current user's goals, plans, background knowledge and (false) beliefs, i.e., maintain a so-called “user model”. Apart from cooperativity aspects, such a model is also necessary for intelligent coherent dialog behavior in general. This article surveys recent research on the problem of how such a model can be constructed, represented and used by a system during its interaction with the user. Possible applications, as well as potential problems concerning the advisability of application, are then discussed. Finally, a number of guidelines are presented which should be observed in future research to reduce the risk of a potential misuse of user modeling technology.
