Multi-view Chinese Treebanking

We present a multi-view annotation framework for Chinese treebanking, which uses dependency structures as the base view and supports conversion into phrase structures with minimal loss of information. A multi-view Chinese treebank was built under the proposed framework, and the first release (PMT 1.0) containing 14,463 sentences is be made freely available. To verify the effectiveness of the multi-view framework, we implemented an arc-standard transition-based dependency parser and added phrase structure features produced by the phrase structure view. Experimental results show the effectiveness of additional features for dependency parsing. Further, experiments on dependency-to-string machine translation show that our treebank and parser could achieve similar results compared to the Stanford Parser trained on CTB 7.0.
