虽然语言学家和哲学家试图以各种方式建立模型，其中我们所说的意思可以依赖于非语言语境，但这项工作总体上集中在如何利用非语言语境来建立或锚定参考或其他上下文敏感的表达。在本文中，我们关注的是一些例子，在这些例子中，非语言事件贡献了整个话语单元，作为连贯关系的参数，而没有上下文敏感表达的中介。我们使用自然发生和构建的例子来突出这些相互作用，并认为应该扩展现有的基于连贯的话语描述来对它们进行建模。我们还认为，以这种方式扩展基于一致性的帐户是一项重要的任务。它迫使我们重新评估非语言语境和修辞关系的基本概念，以及话语结构、演变和解释的模型。我们的论文论述了这些类型的交互所需要的概念和技术上的修订。
While linguists and philosophers have sought to model the various ways in which the meaning of what we say can depend on the nonlinguistic context, this work has by and large focused on how the nonlinguistic context can be exploited to ground or anchor referential or otherwise context-sensitive expressions. In this paper, we focus on examples in which nonlinguistic events contribute entire discourse units that serve as arguments to coherence relations, without the mediation of context-sensitive expressions. We use both naturally occurring and constructed examples to highlight these interactions and to argue that extant coherence-based accounts of discourse should be extended to model them. We also argue that extending coherence-based accounts in this way is a nontrivial task. It forces us to reassess basic notions of the nonlinguistic context and rhetorical relations as well as models of discourse structure, evolution, and interpretation. Our paper addresses the conceptual and technical revisions that these types of interaction demand.
