The parsing methodology investigated here has previously been applied to Swedish, where promising results were obtained with a relatively small treebank (approximately 5000 sentences for training), resulting in an attachment score of 84.7% and a labeled accuracy of 80.6% (Nivre et al., 2004).
1 since there are no comparable results available for Swedish, it is difficult to assess the significance of these findings, which is one of the reasons why we want to apply the method to a benchmark corpus such as the the Penn Treebank, even though the annotation in this corpus is not ideal for labeled dependency parsing.
