基于GPSG文法的汉语语义表达结构CFAS

CFAS—A Representation Structure of Chinese Semantics Based on GPSG

基于ＧＰＳＧ文法的汉语语义表达结构ＣＦＡＳ，它以函词和变元的关系来统一描述汉语句子的谓语和主、宾、状语等之间的关系以及汉语短语内部修饰与被修饰、限定与被限定成分之间的关系，即以形式化的方式描述汉语的句子和短语组成成分的语义结构．在此基础上，进一步介绍了以汉语的ＧＰＳＧ句法结构作为输入，将其转换为ＣＦＡＳ语义表达结构作为输出的实验系统ＣＦＡＳＥＲ．

A structure for the representation of the meaning of Chinese sentence,Chinese Functor Argument Structure (CFAS),and a prototype of the semantic analyzer based on CFAS are presented.In CFAS the relation among the predicate,the subject and the object etc.of a sentence is described as a FAS relation.Furthermore,all relations between the determiner and the determinatum,the modifier and the modificand etc.are interpreted as argument structures.That is to say,the predicate of a sentence is taken as a functor,the subject and the object ect.are taken as arguments.And the determiner or the modifier of the phrase structure is described as a functor,and the determinatum or the modificand is described as an argument in the same way.A prototype of the analyzing system based on CFAS named CFASER is also implemented,which receives a syntactic sentence structure in GPSG,and outputs a CFAS sentence structure.
