Syntax-based translation models that operate on the output of a source-language parser have been shown to perform better if allowed to choose from a set of possible parses. In this paper, we investigate whether this is because it allows the translation stage to overcome parser errors or to override the syntactic structure it- self. We find that it is primarily the latter, but that under the right conditions, the transla- tion stage does correct parser errors, improv- ing parsing accuracy on the Chinese Treebank.
