For example, given a pair of words A and B, where B would be a verbal predicate, we train a local classifier to assign the label "SBJ:A0", signifying that A is the modifier in a subject dependency relation with its head B, as well as that A is the argument with the A0 role of predicate B.
we merge the class labels of the two tasks into single labels, and present the classifiers with examples with these labels.
