... the intersection Vqr of the supports of q and r. This is of interest from a computa- tional point of view because Vqr tends to be a relatively small subset of V, the set of all verbs. Furthermore, ... purpose of improving probability estima- tion for unseen cooccurrences. Our contribu- tions are three-fold: an empirical comparison of a broad range of measures; a classif...
