Evolution of Italian Treebank and Dependency Parsing towards Universal Dependencies
Giuseppe M. Attardi, Simone Saletti, Maria Simi · Accademia University Press eBooks · 2015
We highlight the main changes recently undergone by the Italian Dependency Treebank in the transition to an extended and revised edition, compliant with the annotation schema of Universal Dependencies. We explore how these changes affect the accuracy of dependency parsers, performing comparative tests on various versions of the treebank. Despite significant changes in the annotation style, statistical parsers seem to cope well and mostly improve.
