语篇表示理论下的预设投射问题

Analysis of the presupposition projection problem in discourse representation theory

预设是语言学和逻辑学研究中一个亘古常新的话题,学界普遍关注预设的投射问题及其解决途径。克里普克认为,探讨投射问题应当关注代词的指代现象以及副词的影响;利用语篇表示理论处理代词指代照应的方法来分析预设,是以语言学视角分析投射问题的新路径。依托范德森特和克拉默的思路,以条件句为例,在语篇表示结构中分析子句预设的投射情况;指出在约束操作下子句的预设不能成功投射到整个复合表达式中;而在接纳操作成功时,子句的预设能够成功投射,成为整个复合表达式的预设。

Presupposition is a timeless new topic in the study of modern linguistics and logic.Academia focuses on the projection problem for presupposition and its solutions.Kripke thinks that we should concern an important anaphoric element carried by the presuppositional terms.Using the method of pronominal anaphora resolution in the Discourse Representation Theory to analyze the projection problem is a new approach to presupposition analysis.This paper based on the theory of Van der Sandt and Emiel Krahmer studies the projection of the presupposition of clauses in the conditional sentence,and points out the presupposition of clauses can’t project successfully through the binding operation,while it can project successfully through the accommodation operation,and become the presupposition of the whole compound expression.
