... covering 38 semantic roles out of 52 roles present in the total training set. We use one unlabeled training set (U) for in- domain and another for out-of-domain experi- ments. The former is the ... How- ever, this corpus only exemplifies the semantic role assignment by selecting some illustrative examples for annotation. This questions its suita- bility for statistical learni...
