To compare our results with previously published results in SRL, we carried out an experiment comparing our system to the top system (Punyakanok et al., 2008) in the CoNLL-2005 Shared Task.
comparison is nontrivial since the output of the CoNLL-2005 systems was a set of labeled segments, while the CoNLL-2008 systems (including ours) produced labeled semantic dependency links.
