| Abstract: | Japanese dependency analysis is recognized as a basic technique in Japanese sentence analysis.This paper proposes a method for Japanese dependency analysis based on Conditional Random Fields,the existence information of functional word and context information are adopted as features.The experimental results in Kyoto University Corpus show that this method is effective,dependency accuracy and sentence accuracy achieve 89.26% and 45.90% respectively. |
