Dependency or Span, End-to-End Uniform Semantic Role Labeling
Table 2: End-to-end span SRL results on CoNLL-2005 and CoNLL-2012 data, compared with previous systems in terms of precision (P), recall (R), F1-score. The CoNLL-2005 contains two test sets: WSJ (in-domain) and Brown (out-of-domain).
['End-to-End', 'CoNLL-2005 WSJ P', 'CoNLL-2005 WSJ R', 'CoNLL-2005 WSJ F1', 'CoNLL-2005 Brown P', 'CoNLL-2005 Brown R', 'CoNLL-2005 Brown F1', 'CoNLL-2012 (OntoNotes) P', 'CoNLL-2012 (OntoNotes) R', 'CoNLL-2012 (OntoNotes) F1']
The upper part of table presents results from single models. Our model outperforms the previous models with absolute improvements in F1-score of 0.3% on CoNLL-2005 benchmark. Besides, our single model performs even much better than all previous ensemble systems.
