This paper presents a set of experiments per- formed on parsing the Basque Dependency Treebank. We have applied feature propaga- tion to dependency parsing, experimenting the propagation of several morphosyntactic fea- ture values. In the experiments we have used the output of a parser to enrich the input of a second parser. Both parsers have been gener- ated by Maltparser, a freely data-driven de- pendency parser generator. The transforma- tions, combined with the pseudoprojective graph transformation, obtain a LAS of 77.12% improving the best reported results for Basque.
