1For English (PropBank/NomBank), the model achieves a F1-score of 87.9 percentage points, the best result reported on any SRL data set to date.
 For English (FrameNet), the model achieves a F1-score of 79.3% (given gold frames), an improvement of 2.4 points over previous work.
 The German model achieves a F1-score of 81.4%, the current state-of-the-art result and the first to crack the 80.0 point mark.
