We therefore begin by presenting a probabilistic model ofthe plausibility of verb argument relations, which we estimate as the probability ofencountering a verb argument pair in the relation specified by a thematic role in arole annotated training corpus. This model faces a significant sparse data problem,whichwealleviatebycombiningtwoorthogonalsmoothingmethods.
