The most common form of parser evaluation is to apply the Parseval metrics to phrase-structure parsers based on the Penn Treebank, and the highest reported scores are now over 90% (Bod, 2003;Charniak and Johnson, 2005).
and third, we provide the first evaluation of a widecoverage CCG parser outside of CCGbank, obtaining impressive results on DepBank and outperforming the RaSP parser  by over 5% overall and on the majority of dependency types.
