话语表现理论(DRT)是一种动态地描述自然语言意义的形式语义学理论。DRT由“句法规则”、“DRS的建构规则”和“DRS的语义解释”三部分构成。DRS在整个DRT理论中起着至关重要的作用。DRT通过DRS来展示人们使用语言、理解语言的心理表现,企图克服模型语义学所面临的心理现实问题。DRS的建构过程,是一种动态的渐进过程,体现了语言信息的递增性和连贯性的特点。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 is a formal semantics theory, which describes the meaning of natural language. DRT consists of syntactic rules, DRS -Construction rules and DRS semantic explanation. DRS plays an important role in DRT. DRT shows mental representation that people use and understand language, and tries to overcome mental re- alistic problems that model - theoretic semantics face. The process of DRS - Construction, a dynamically gradual process, embodies the increment and cohesion of language information. The study of DRT for natural language is in- volved in not only the truth condition of sentence, but the concrete context, which accords with people' s cogni- tive process of understanding language.
