This paper presents an effective algorith- m of annotation adaptation for constituen- cy treebanks, which transforms a treebank from one annotation guideline to anoth- er with an iterative optimization proce- dure, thus to build a much larger treebank to train an enhanced parser without in- creasing model complexity. Experiments show that the transformed Tsinghua Chi- nese Treebank as additional training da- ta brings significant improvement over the baseline trained on Penn Chinese Tree- bank only.
