组合范畴语法产生和发展的动因探析--从句法演算的视角看

The Motivational Analysisabout the Emergence and Development of Combinatory Categorial Grammar——From the Perspective of Syntactic Calculus

AB—演算刻画句法推演能力太弱,许多合语法的语句在AB—演算中没有合适的推演形式。斯蒂德曼在AB—演算的基础上增加组合规则,产生了原生态的组合范畴语法CCG,大大增强了范畴语法处理自然语言的能力,比如它能够处理像非成分毗连这样的非连续问题。但是对于话题句、尤其是汉语中存在的各类话题句,原生态CCG显得无能为力,因此需要对原生态CCG进行扩展。在原生态CCG中添加话题化规则和话题化范畴,可以有效地处理汉语的各类话题化语句。

AB-calculus is too weak, and many correct sentences which present to be appropriate in grammar rule can not be derived with it. Steedman added the combinatory rules to the AB- calculus to invent the stand- ard： Combinatory Categorial Grammar named CCG, and CCG greatly proved its processing ability to Chi- nese. For example, CCG can deal with discontinuous problems such as the coordination of non-constituent. For topicalised sentences, especially for Chinese topicalised sentences, the standard CCG seems too weak to deal with them, so we need to extend it. The author adds some topicalised rules and topicalised Categories to the standard CCG, and efficiently deals with all kinds of Chinese topicalised sentences.
