Analysis of the Hierarchical Chinese Functional Chunk Bank
Hang Yu · Zhongwen xinxi xuebao · 2008
Through an experimental analysis of the relation between the length and the structure of functional chunks and the performance of the parser,this paper reveals that it is the long,complex-structured functional chunks that are the major difficulty in parsing.Therefore,this paper proposes a new hierarchical functional chunk scheme and automatically generates the new functional chunk bank from Tsinghua Chinese Tree Bank(TCT).Further extensive researches about the length and structure distribution of the new chunk bank indicates that the new functional chunks bear short length and simple structure,which will help to improve the performance of functional chunk parser.
