基于情境理论的汉语理解模型

A Model of Chinese Understanding Based on the Situation Theory

本文系统地介绍了一种新的语义分析理论——情境理论,并对这种理论作了扩充与发展.在此基础上建造了一个适合汉语特点的自然语言理解模型,导出了汉语中各类词和句子情境含义的形式化表示——情境框架,并为确定这些框架中所表达的语义,构造了一个基于语义场的关系演算系统.通过将语用约束条件引入情境框架,把语义分析和语用分析有机地结合起来,并统一于一种形式化的内部表示之中,从而在理论上突破了迄今为止将语义和语用分析割裂开来分别处理的传统观点与作法.

In this paper, situation theory, a new theory about semantic analysis, is systematically introduced, extended and developed. Based on the theory a model of natural language understanding is built, which is suited for the features of Chinese understanding. A formal expression for the situationmeaning of all kinds of Chinese words and sentences, i. e., situation-frames, is derived and a relationcalculus system for finding out the semantic meanings of the situation-frames is constructed. The semantic analysis and pragmatic analysis are well combined by putting the pragmatic constrains in the situation-frames, and unified in a uniform internal expression.
