SDRT中的真实修辞关系

On Veridical Rhetorical Relations in SDRT

SDRT的核心概念是修辞关系,认为话语意义受制于话语自身的修辞结构,即话语语段之间或者话语序列之间的逻辑结构,包括叙述、解释、详述、因果、背景、对比、平行、纠正、证据、反证据等。所有的真实修辞关系符合真实修辞关系满足图式。满足图式确保只有当被关系的自变量所标记的内容和ΦR(x1,x2)中被明确的"额外的内容"把输入语境和输出语境关联起来时,真实关系才把输入语境和输出语境联系起来。

Rhetorical relations, which are the core concepts of SDRT, argue the meaning of a discourse depends upon and interacts with its rhetorical structure, which we also call logical structure between discourse segments or discourse sequences, including narration, explanation, elaboration, result, background, contrast, parallel, correction, evidence, counterevidence, etc. All veridical rhetorical relations conform to satisfaction schema for veridical rhetorical relations. This schema ensures that veridical relations relate an input context to an output one only if the contents that are labeled by the relation＇ s arguments （plus extra content specified in φR（π1,x2）） also do this.
