A Study on Chinese Prosodic Hierarchy Prediction Based on Dependency Grammar Analysis
Yunfang Wu · Zhongwen xinxi xuebao · 2008
Different prosodic hierarchy could divide texts into several prosodic chunks for better speaking and understanding.Currently,many shallow features such as part-of-speech,length of word are used to predict the prosodic hierarchy.But these features are not powerful for some prosodic unit prediction such as prosodic phrase.In fact,syntactic structure is in close touch with prosody structure.They influence and restrict each other.In this paper,based on dependency grammar,some deep features which are related with prosody hierarchy are extracted.Compared to the shallow features,the deep features such as inner-arc span and inner-arc type are more effective on the prediction of the middle level such as prosodic phrase.The F-score increases about 11%.
