For the complete SRL task, we used the previous BC and all the available data, that is, the sections from 2 to 21, for training the role multiclassifier.
still, although we only used a small fraction of the available training data (i. e., only 2 sections out of 22 were used to train the re-ranker) our system's accuracy is in line with state-of-the-art systems (Carreras and Màrquez 2005) that do not employ tree kernels.
