Abstract

We present a set of experiments on dependency parsing of the Basque Dependency Treebank (BDT). The present work has examined several directions that try to explore the rich set of morphosyntactic features in the BDT: i) experimenting the impact of morphological features, ii) application of dependency tree transformations, iii) application of a two-stage parsing scheme (stacking), and iv) combinations of the individual experiments. All the tests were conducted using MaltParser (Nivre et al., 2007a), a freely available and state of the art dependency parser generator.
