This paper proposes a method of correct- ing annotation errors in a treebank. By us- ing a synchronous grammar, the method transforms parse trees containing annota- tion errors into the ones whose errors are corrected. The synchronous grammar is automatically induced from the treebank. We report an experimental result of apply- ing our method to the Penn Treebank. The result demonstrates that our method cor- rects syntactic annotation errors with high precision.
