There are several methods of detecting annotation errors in a phrase structure treebank (Dickinson and Meurers, 2003;Ule and Simov, 2004;Dickinson and Meurers, 2005;Boyd et al., 2007;Dickinson, 2009;Przepiórkowski and Lenart, 2012;Kulick et al., 2013;Faria, 2014).
there is little work on treebank error correction.
