从量化和时间表达的角度看DRT

A Study of DRT from the Angle of Quantified and Temporal Representation

话语表征理论是一种动态语义学理论,它摆脱了一阶谓词逻辑的限制,将处理对象扩展到一个句子以上的话语,揭示名词与代词跨句子的指代照应关系,解决了"驴子句"的语义疑难问题。DRT对复数名词和数目词组进行了精确地刻画,并吸收了广义量词理论的长处,将广义量词看作是两个集合间的关系。DRT还能解释句子系列(即话语)在时间方面的复杂关系,精妙地刻画动词的时态、时体、时相等众多时间特征。DRT对自然语言的研究不仅涉及到句子的真值条件,还涉及到具体的语境,这符合人们理解语言的认知过程。

DRT,which is a dynamic semantics theory,shakes off the limit of first-order predicate logic,treats the anaphoric relations between nouns and pronouns across sentence boundaries,solves the semantics problem of donkey sentence.DRT accounts for plural nouns,numeral phrases,generalized quantifiers and temporal distinctions of verbs such as tense,aspects and phase.The study of DRT for natural language is involved in not only the truth condition of sentence,but the concrete context,which accords with people＇s cognitive process of understanding language.
