In fact, our corresponding result on the FrameNet corpus (Table 2) is P =0.784, R=0.571, F 1 =0.661, where the corpus contains much more data, its sentences come from a standard written text (no disfluencies are present) and it is in English language, which is morphologically simpler than Italian.
the Italian corpus includes optimal syntactic annotation which exactly fits the frame semantics, and the number of frames is lower than in the FrameNet experiment.
