Many different types of features have been shown to improve accuracy in parse reranking. A class of features that thus far has not been considered is based on a pro- jection of the syntactic structure of a trans- lation of the text to be parsed. The intu- ition for using this type of bitext projec- tion feature is that ambiguous structures in one language often correspond to un- ambiguous structures in another. We show that reranking based on bitext projection features increases parsing accuracy signif- icantly.
