The result for the first baseline, 0.0, is the same as in SemEval, and a natural consequence of B-Cubed since there are no pairs within a class.
while the overall performance of the All-instances, One sense baseline in SemEval surpasses its best participating system (achieving the score of 0.623), the result for this baseline on our verb clustering is much lower (0.069), suggesting the task is significantly more difficult, due to the high number of clusters.
