摘要：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.
