... With grammatical role labeling, for example, there is no way to explicitly express global constraints that, say, the verb “to give” must have 3 arguments of a particular grammatical role. Among the ... a grammatical role can have. Here, we have to distinguish among our two settings. In setting one (all case roles of all frames of a verb are collapsed into a single set of case roles), w...
