Following prior work BIBREF56 , BIBREF57 , BIBREF17 , we employ the MNCut spectral clustering algorithm BIBREF58 , which has wide applicability in similar NLP tasks which involve high-dimensional feature spaces BIBREF59 , BIBREF60 , BIBREF18 . 
 Question: What clustering algorithm is used on top of the VerbNet-specialized representations?
MNCut spectral clustering algorithm BIBREF58
