| 摘要: |
| 本文首先给出了一种自然语言计算模型,该模型把自然语言交流过程划分为三个层次:语言形式,表层语义和深层语义,从而将自然语言理解抽象为一个复合函数UP(s,k),依据这个模型,我们设计了一个汉语理解系统,这个系统具有良好的扩展性和可移植性,该系统采用汉语语义结构文法来分析汉语句子,把语法分析和语义分析有机地结合在一起,文中形式定义了词语的深层语义以及深层语义的基本运算,给出了分析器、理解器以及生成器的算法。 |

| Abstract: |
| We put forward a computational model of natural language in which the process of communicating in natural language is divided into three levels: linguistic form, surface semantics and deep semantics. Based on this model we design a Chinese language understanding system which could be easily transported from one domain to another . A new grammar, Chinese Semantic Construction Grammar, is introduced, which could describes not only syntactic form but also semantic form of a sentence and performs syntacric anallysis and semantic anslysis simultaneouslyduring parsing.The deep semantics of a word or a phrase and the basic oprations of deep semantics are formally defined.The algorithms of the parser,the parser,the understander and the generator of the system are also presented. |
