Abstract

We report on some recent parse selection experiments carried out with GG, a large-scale HPSG grammar for German. Using a manually disambiguated treebank derived from the Verbmobil corpus, we achieve over 81% exact match accuracy compared to a 21.4% random baseline, corresponding to an error reduction rate of 3.8.
