A Theoretical Study of Interface Between Syntactic and Discourse Structures

本研究是对控制句法结构和语篇结构的构建界面的理论研究。稻田对嵌入小句的句法语义结构和词汇语义结构进行了研究，论证了理清句子的事件结构以及句法和词汇概念结构之间的界面研究的意义；Takubo以语篇管理理论为基础，阐明了控制语篇结构的因素，包括句子助词、呼唤形式和其他情态表达；Arita研究了从属从句和条件从句中的各种时态结构，并试图按照Takubo的语篇管理理论的思路来解释这些现象。她还证明了FauConnier的心理空间模型，如果表述得当，也可以解释包括因果链在内的日语时态现象。村尾武夫还证明，语篇中的某种因果链与句子的词汇概念结构的事件结构密切相关。通过与戈德堡、兰加克等人的讨论，他澄清了语篇结构的所谓认知方面。

The present research project was a theoretical study of building interface which controls syntactic and discourse structures. We also attempted to clarify various interface factors that contribute to the mapping of lexical, conceptual, or event structures into syntactic and discourse structures.Inada has researched syntactic and lexical semantic structures of embedded clauses and demonstrated the significance of clarifying the event structures of sentences and the study of interface between syntactic and lexical conceptual structures.Takubo, based upon the theory of discourse management, clarified the factors that function to control discourse structures including sentence particles, vocative forms, and other modality-related expressions.Arita investigated various tense structures in subordinate clause and conditional clauses, and attempted to show these phenomena can be naturally explained along the line presented in Takubo's Discourse Management Theory. She also demonstrated that Mental Space Model by Fauconnier, if properly reformulated, can also accommodate Japanese tense phenomena including causal chains.Murao also demonstrated that some kind of causal chains in discourse are closely related to event structures of lexical conceptual structures of a sentence. Through his discussion with Goldberg, Langacker and others, he has clarified so-called cognitive aspects of discourse structures.
