Abstract:

Conversation, as the basic form of “language use”, has posed considerable challenges for formal linguistic studies, as well as for natural language processing. Due to its interactivity, dynamicality, and context dependency, there is still little operation mechanism research concerning the formal characterization of the dynamic parsing process of conversation. Within the framework of dynamic syntax that defines representations of content and of context both dynamically and structurally, this study attempts to provide a parsing-based account of conversational dialogues in Mandarin illustrated by the dynamic parsing process of conversational repair examples. It is concluded that natural language conversation can be accounted for adequately by placing a high premium on context and on the interaction among structural, lexical, and pragmatic information.

Keywords: conversation; repair; dynamic parsing; linguistic context; working mechanism; dynamic syntax

摘要：

会话是人类语言最基本的使用形式，也是自然语言处理中的一个难题。会话的交互性、实时动态性及语境依赖性等特点，一直是脱离语境（context-free）的传统形式语法理论研究的一个盲点。本文基于动态句法理论框架，采用渐进式的解析方式，以会话修正语料为例，尝试对汉语会话的语义识解过程进行形式化描写，对语句的语义内容和语言环境均作出形式化表征，力求以结构化方式清晰地展现会话赖以生存的语境因素。通过对会话语义的动态解析，本文发现，将语境因素纳入理论模型，同时重视结构、语义及语境之间的互动关系在会话实时理解与表达中的作用，能够使我们更好地探究自然语言会话的运作机制。
