GraFo is a left corner parser for Italian, based on explicit rules manually coded in a unification formalism. As the linguistic coverage of GraFo is still quite limited, the parser produces complete parse trees for a small percentage of sentences. This paper presents a number of strategies to recover from GraFo parsing failures. The various techniques have been evaluated on the data provided by the EVALITA 2007 evaluation campaign.

Abstract
GraFo is a left corner parser for Italian, based on explicit rules manually coded in a unification formalism. As the linguistic coverage of GraFo is still quite limited, the parser produces complete parse trees for a small percentage of sentences. This paper presents a number of strategies to recover from GraFo parsing failures. The various techniques have been evaluated on the data provided by the EVALITA 2007 evaluation campaign.File in questo prodotto:
