In planning their linguistic expressions, speakers and writers are often able to leave out informationally redundant grammatical material, such as when the verb "call" is omitted in "Fred called, but Sheila didn't". This process, known as ellipsis, is widespread across the languages of the world, and is particularly common in informal language and dialogue. Among the many varieties of ellipsis is sluicing, where what is omitted is not a verb but an entire sentence. For example, a speaker may choose to leave out the understood sentence "he called" after "why" in a sentence like: "He called, but I don't know why".Ellipsis poses challenging scientific and engineering problems. Research over the past 50 or 60 years has demonstrated that the principles permitting ellipsis involve many different kinds of information (grammatical structure, the dynamics of the discourse context, and real-world knowledge), but the precise character of these principles and their interaction is still an open question. Progress has been hampered by the lack of a crucial resource type: databases of felicitous uses of ellipsis that are large enough to validate theories against, and rich enough to form the basis for machine learning.The first goal of this project is to build such a database for sluicing and to make it freely available to language scientists and engineers. This resource will be a large, curated corpus of naturally occurring ellipses, annotated at a level of sophistication that will allow a range of analytic questions to be probed quantitatively. As the curation and annotation proceed, patterns that emerge from the data will be used to investigate the interplay between grammar and context that makes ellipsis possible. Since ellipsis is a pervasive feature of human language, to better understand how it works is to better understand the nature of human linguistic behavior itself. This project should also stimulate technological innovation in an area of urgent need: in designing more sophisticated systems for interfacing with natural human conversation, which is replete with ellipses of every kind.

在计划他们的语言表达时，说话者和作家经常能够省略信息上多余的语法材料，例如当动词“call”在“Fred call，But Sheila‘t”中被省略时。这一过程被称为省略，在世界各地的语言中普遍存在，在非正式语言和对话中尤为常见。在许多省略中有一种是省略，省略的不是动词，而是整个句子。例如，演讲者可能会选择省略理解的句子“他叫了，但我不知道为什么”中的“为什么”之后的“他叫”。省略号提出了具有挑战性的科学和工程问题。过去50或60年的研究表明，允许省略的原则涉及许多不同类型的信息(语法结构、语篇语境的动态和现实世界的知识)，但这些原则的确切特征及其相互作用仍然是一个悬而未决的问题。由于缺乏一种重要的资源类型，进展受到了阻碍：省略的恰当使用的数据库足够大，足以验证理论，足够丰富，足以形成机器学习的基础。这个项目的第一个目标是建立这样一个用于冲刷的数据库，并向语言科学家和工程师免费提供。这一资源将是一个自然产生的省略的大型精选语料库，在一定程度上进行注释，将允许对一系列分析问题进行定量探讨。随着精选和注释的进行，从数据中出现的模式将被用来调查语法和语境之间的相互作用，从而使省略成为可能。由于省略是人类语言的一个普遍特征，更好地理解它是如何工作的就是更好地理解人类语言行为本身的本质。这个项目还应该刺激一个迫切需要的领域的技术创新：设计更复杂的系统，用于与自然的人类对话进行交互，其中充满了各种省略。
