Preparing SNACS for Subjects and Objects

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 objects-directly, without reference to a frame lexicon. We present new guidelines for English and the results of an interannotator agreement study.
