面向计算的现代汉语双音词分离及其语法意义与特性研究

A Grammatical Analysis of Disyllable Word Split in Modern Mandarin:A Computational Linguistic Perspective

汉语缺乏严格的形态束缚,在句子里双音词经常由于嵌入相关句法成分而呈现出分离。为了提高自然语言处理中语段分词、词性标注及基于规则的句子语义计算的准确性与有效度等,文章系统考察了现代汉语里典型词与离合词的分离现象,挖掘并刻画出它们各自形成的语法动因、条件、意义以及分离而成的成分的语法特性等,从而对现代汉语中双音词的分离做出了系统多层级的理论思考。文章指出典型词的分离是语用作用的结果,分离结构的意义是主观的;而离合词分离是句法语义作用的产物,意义是客观的。

With flexible morphological rules, Chinese is common to be observed for the disyllable word split by int- setting some syntactical constituents of a sentence. To facilitate the word segmentation, part-of-speech tagging and semantic computing, the paper systematically discusses two types of the disyllable word split in Mandarin： one for the the Separable word, and the other is for the Prototype word. It examines describes the grammatical movitation of their formation~ properties, and meanings, indicating that 1） the Prototype word split is caused by pragmatic fac- tors, with subjective structures and grammatical meanings; yet 2） the Separable word split is caused by the syntactic and semantic expression, with objective structures and meanings.
