We presented an empirical study of Chinese base NP
chunking on this corpus. First,We extracted the base noun phrase (base
NP) chunking corpus from UPENN Chinese Treebank-5(CTB-5). we made an
evaluation on the corpus to clarify the performance of stateof-the-art
models in Chinese base NP chunking. Then we proposed two combining
approaches in order to improve the performance of Chinese chunking.
Finally we gave primary results on chunking with multi classifiers
System.
