The effect of a perfect MWU recognizer is simulated through manual annotation of MWUs in corpus data used for training and testing two different versions of the parser, one which is lexicalized and one which is not. The results show a significant improvement in parsing accuracy not only for MWUs themselves but also with respect to surrounding syntactic structures. The improvement is consistent for both versions of the parser and holds for both labeled and unlabeled accuracy. The greatest improvement corresponds to a 5 % error reduction, which is substantial given the relatively low frequency of MWUs in the data. In addition to a quantitative analysis, we also present an analysis of some of the most important error types that are eliminated by the recognition of MWUs. 1.
