In contrast to previous models, this model does not implement semantic role plausibility as 'fit with verb selectional preferences', but directly captures the semantic role ambiguity problem comprehenders have to solve when confronted with sentences that contain structural ambiguities like the MV/RR ambiguity, namely deciding which semantic role a noun has in the event denoted by the verb.
the model should be easily extensible towards a complete model of any sentence-level ambiguity that revolves around a semantic role ambiguity.
