ABSTRACT: The aim of Evalita Parsing Task is at defining and extending Italian state of the art parsing by encouraging the application of existing models and approaches. As in the Evalita'07, the Task is organized around two tracks, i.e. Dependency Parsing and Constituency Parsing. As a main novelty with respect to the previous edition, the Dependency Parsing track has been articulated into two subtasks, differing at the level of the used treebanks, thus creating the prerequisites for assessing the impact of different annotation schemes on the parsers performance. In this paper, we describe the Dependency Parsing track by presenting the data sets for development and testing, reporting the test results and providing a first comparative analysis of these results, also with respect to state of the art parsing technologies.
