GUS是我们打算作为语言理解研究计划的一部分构建的一系列实验计算机系统中的第一个。在很大程度上，这些系统将发挥定期进度报告的作用，总结我们所了解到的情况，评估我们一直遵循的各种调查路线的相互一致性，并提出今后工作中需要更加重视的地方。GUS（亲切的理解者系统）旨在让一个富有同情心和高度合作的人参与英语对话，在非常有限的话语范围内针对特定目标。作为一个起点，GUS被限制在一个旅行代理人的角色，在与一个客户的对话中，这个客户想做一个简单的回程到加州的一个城市，有很好的理由限制计算机系统的话语领域，即参与英语对话。专门化系统可以谈论的主题允许它实现某种程度的现实主义，而不包括人类知识或英语语言的所有可能性。它还为用户提供了参与对话的特定动机，从而缩小了GUS必须对用户目的的期望范围。一个以这种方式限制的系统将更能够在其权限范围内引导对话。
GUS is the first of a series of experimental computer systems that we intend to construct as part of a program of research on language understanding. In large measure, these systems will fill the role of periodic progress reports, summarizing what we have learned, assessing the mutual coherence of the various lines of investigation we have been following, and suggesting where more emphasis is needed in future work. GUS (Genial Understander System) is intended to engage a sympathetic and highly cooperative human in an English dialog, directed towards a specific goal within a very restricted domain of discourse. As a starting point, GUS was restricted to the role of a travel agent in a conversation with a client who wants to make a simple return trip to a single city in California.There is good reason for restricting the domain of discourse for a computer system which is to engage in an English dialog. Specializing the subject matter that the system can talk about permits it to achieve some measure of realism without encompassing all the possibilities of human knowledge or of the English language. It also provides the user with specific motivation for participating in the conversation, thus narrowing the range of expectations that GUS must have about the user's purposes. A system restricted in this way will be more able to guide the conversation within the boundaries of its competence.
