Chinese Word Similarity Computing Based on Semantic Tree
Jiajun Chen · Zhongwen xinxi xuebao · 2010
Word similarity analysis and computing is one of the key technologies in natural language processing.It can offer substantial help to parsing,machine translation and information retrieval etc.Recently Chinese word similarity computing based on Hownet has become a hot research issue,though most of which are improvements or modifications to what was proposed in(Liu,2002).Based on new Hownet(2007) with its concept frame and the multi-dimension semantic expression form,this paper proposes a new method to analyze and compute Chinese word similarity from three dimensions: the main sememe,the main sememe frame and the concept characteristic description.This method also distinguishes the semantic similarity and the syntax similarity in computation.Experiment shows that the method produces a good performance.
