本文提出了一种纠正树库中注释错误的方法。通过使用同步语法，该方法将包含注释误差的解析树转化为纠正误差的误差。同步语法会自动从树仓诱导。我们报告了将我们的方法应用于宾夕法尼亚州库的实验结果。结果表明，我们的方法以高精度纠正句法注释误差。
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.
