Abstract. This paper describes CELI’s participation to the EVALITA 2009 dependency evaluation task, which was based on a symbolic dependency grammar for Italian. The discussion on the results achieved by such a grammar emphasizes the fact that they are obtained by linearizing the CoNLL input and parsing it from scratch, thus generating extra errors due to lexicon look-up and POS tagging. In the final section we provide some explanation of the fact that the scores obtained in the pilot subtask were lower than the ones for the main subtask. Overall, however, the results of the participation prove that a rule approach is viable and sustainable for real life applications.
