A Theoretical Study of Interface Between Syntactic and Discourse Structures

本课题的研究内容是构建控制句法和语篇结构的界面的理论研究。我们还试图澄清有助于将词汇、概念或事件结构映射到句法和话语结构的各种界面因素。Inada对嵌入子句的句法和词汇语义结构进行了研究，论证了澄清句子的事件结构以及研究句法和词汇概念结构之间的接口的意义。Takubo以语篇管理理论为基础，明确了控制语篇结构的因素，包括句子小品、祈使形式和其他与情态相关的表达。有田研究了从句和条件从句中的各种时态结构，并试图表明这些现象可以按照Takubo的话语管理理论的思路自然地解释。她还证明了Fauconnier的心理空间模型，如果适当地重新表述，也可以适应包括因果链在内的日本紧张现象。Murao还论证了语篇中的某些因果链与句子词汇概念结构的事件结构密切相关。通过与Goldberg、Langacker等人的讨论，他澄清了所谓的话语结构的认知方面。

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.
