There is significant evidence in the literature that integrating knowledge about multiword expressions can improve shallow parsing ac- curacy. We present an experimental study to quantify this improvement, focusing on com- pound nominals, proper names and adjective- noun constructions. The evaluation set of multiword expressions is derived from Word- Net and the textual data are downloaded from the web. We use a classification method to aid human annotation of output parses. This method allows us to conduct experiments on a large dataset of unannotated data. Experi- ments show that knowledge about multiword expressions leads to an increase of between 7.5% and 9.5% in accuracy of shallow pars- ing in sentences containing these multiword expressions.
