In this paper, we present an unlexical- ized parser for German which employs smoothing and suffix analysis to achieve a labelled bracket F-score of 76.2, higher than previously reported results on the NEGRA corpus. In addition to the high accuracy of the model, the use of smooth- ing in an unlexicalized parser allows us to better examine the interplay between smoothing and parsing results.
