统一解析三种语法体系，解决语言连续与不连续结构的表示难题
A Unified Representation for Continuity and Discontinuity: Syntactic and Computational Motivations
- 提出对应原理，统一句法结构的表示框架
- 以土耳其语从句为例展示不连续结构的统一建模方法
- 简化神经认知处理复杂度，适合语法理论与计算语言学研究者
本文从句法与计算复杂性角度，推进了三种语法形式体系——短语结构语法（PSG）、依存语法（DG）和范畴语法（CG）——的统一表示。提出对应原理，实现对这三类语法基本表示原则的统一。首先以土耳其语中不连续从句为例，演示逐步构建统一表示的过程，为自然语言中不连续现象提供了新的理论视角，整合了PSG、DG与CG的核心思想，具有重要句法分析意义。随后证明，该统一表示可降低神经认知层面连续与不连续句子的表征与处理复杂度，显著优化基于三类语法原则的计算模型。
原文摘要 · Abstract (English)
This paper advances a unified representation of linguistic structure for three grammar formalisms, namely, Phrase Structure Grammar (PSG), Dependency Grammar (DG) and Categorial Grammar (CG) from the perspective of syntactic and computational complexity considerations. The correspondence principle is proposed to enable a unified representation of the representational principles from PSG, DG, and CG. To that end, the paper first illustrates a series of steps in achieving a unified representation for a discontinuous subordinate clause from Turkish as an illustrative case. This affords a new way of approaching discontinuity in natural language from a theoretical point of view that unites and integrates the basic tenets of PSG, DG, and CG, with significant consequences for syntactic analysis. Then this paper demonstrates that a unified representation can simplify computational complexity with regards to the neurocognitive representation and processing of both continuous and discontinuous sentences vis-à-vis the basic principles of PSG, DG, and CG.
