Correcting Syntactic Annotation Errors Using a Synchronous Tree Substitution Grammar
Yoshihide Kato, Shigeki Matsubara · IEICE Transactions on Information and Systems · 2010
This paper proposes a method of correcting annotation errors in a treebank. By using a synchronous grammar, the method transforms parse trees containing annotation errors into the ones whose errors are corrected. The synchronous grammar is automatically induced from the treebank. We report an experimental result of applying our method to the Penn Treebank. The result demonstrates that our method corrects syntactic annotation errors with high precision.
