面向中文信息处理的现代汉语短语结构规则研究

including a set of Chinese phrase structure rules with rich constraints. It is worth noting that such a RuleBASE must be supported by a lexicon, which contains vast amount of syntactic and semantic features related to every lexical entry. Fortunately, such an electronic lexicon has been developed by the Institute of Computational Linguistics of Peking University. To some extent, the main research presented in this thesis can be regarded as a natural extend of the research of the lexicon.

Chapter two: A classification system of Chinese phrase is put forward firstly, and other syntactic categories for description of phrase structures are also defined. All of these syntactic attributes, which are based on the theory of Phrase-standard Grammar system proposed by Prof. Dexi Zhu, will be used for describing the functions of phrases. At the same time, a semantic expression framework, named as Generalized Valence Mode, is designed for describing the semantic features of a word or a phrase. Furthermore, a simple semantic taxonomy of Chinese content words is also built up. Apparently, all of those syntactic and semantic categories set up in this chapter are the basis of constructing phrase structure rules of Modern Chinese that will be discussed in detail in the Chapter three.
