句子主题的所指依存和信息结构层

Referential Dependency of Sentence Topic and Information Structure Tier

主题算子和焦点都来自概念结构CS的信息结构层。主题化结构是非连续依存结构,不是移位形成的,而是原位生成,主题得到间接许可和原位量化域的语义约束。主题结构的语义通过语法功能层界面影射到句法。鉴于句法区域限制的不足,提出主题化受到所指层的算子对变量所指依存的语义限制。主题结构的不对称在间接许可和所指依存下得到重新解释。

The operator of topic and focus originate in IST in CS. This papers argues that topicalization, as a discontinous dependency, is base generated, instead of movement, and topic is indirectly licensed, and semantically bound by in situ quantifier scope. The semantic representation of topic structure is mapped onto syntax by GFT interface. Topicalization is subject to the semantic constraint of operator-variable referential dependency in RT in light of the deficiencies of locality constraint in syntax. Asymmetries are recast by indirect licensing and referential dependency.
