Research on adpositions and possessives in multiple languages has led to a small inventory of general-purpose meaning classes that disambiguate tokens.Importantly, that work has argued for a principled separation of the semantic role in a scene from the function coded by morphosyntax.Here, we ask whether this approach can be generalized beyond adpositions and possessives to cover all scene participants-including subjects and objectsdirectly, without reference to a frame lexicon.We present new guidelines for English and the results of an interannotator agreement study.
