摘　　要：采用复杂网络的方法对"复句关系词本体知识库"中457个搭配关系进行研究,构建了一个现代汉语的"复句关系词搭配网",并对该网络中的最短路径、平均聚集系数和度分布情况进行分析研究.研究结果表明,"复句关系词搭配网"具有复杂网络的典型特征,而且其小世界效应和无标度特征反映了复句关系词的搭配能力和搭配对象的同现关系,这些特性能够对复句层次关系和逻辑语义关系的自动识别起到重要的作用.This paper adopts the complex network approach to construct a collocation network of chinese complex sentence relation words according to the research of 457 collocation words in Ontology of Complex Sentence Relation Words.We analyze the shortest path,average-clustering coefficient,and degree distribution situation of this network.The results show that the collocation network of complex sentence relation words has the typical characteristics of complex network; and it can reflect the collocation capability and co-occurrence relationship of relation words depending on the efficiency of small-world and non-marked characteristics.The proposed collocation network is applied to identify the gradation and logic relationship of complex sentences automatically.
