In this paper, we focus on the fact that the corpora that exist for implicit SRL differ not only in the semantic role frameworks used (FrameNet vs. PropBank), but also in genre (newswire vs. novels), and classes of annotated predicates (verbs vs. nouns).
they are generally regarded as incompatible, and previous work has concentrated on getting most out of individual corpora, or spending annotation effort on focused extensions of these corpora.
