Functional words play an important role in modern Chinese words,and constitute the syntactic means of Chinese with the word order,so functional words have an important influence on the syntactic analysis.Dependency parsing is a hotspot of research in the field of natural language processing.In order to improve the recognition effect of dependence relation,the usages of functional words are applied to the recognition process of dependence relation in this paper.Through the study of functional words usages,as well as the analysis of dependence relation in the dependency parsing,it found that the coordination relation has close connection with conjunction.And then,the conjunction usages are considered in the recognition process of coordination relation to improve the recognition performance.The experimental results show that,through considering the conjunction usages,the LAS and the UAS of coordination relations have increased 3.43%and 2.29%respectively.
