The Use of Punctuations in Chinese Syntactic Parsing Techniques
Shi Yue-fei · Computer Engineering and Science · 2009
So far,most Chinese syntactic parsing techniques neglect the punctuations or oversimplify their functions.However,it is actually very important information of syntactic characters.According to the features of punctuations in the syntactic structure,this paper proposes a new rule-layered approach.This method makes the punctuations into Chinese syntactic analysis and uses the punctuation role to split long sentences into small sequence sentences.Then each small unit is parsed syntactically and structurally.Finally,we extract the type rule to analyse and complete the parsing tree.Experiments show that this approach not only solves the problem that part of long sentences can not correctly obtain syntactic trees,but also reduces the ambiguities of parsing,and increases efficiency.
