[...] the semantic relations between verbs and their arguments are defined with respect to the subcomponents in the decomposition. For instance, the agent role might be identified with the first argument of the predicate CAUSE. Thus, the majority of proposed lexical semantic representations can be characterized as being of one of two types, "semantic role-centred", taking the form of a "semantic role list", or "predicate-centred", taking the form of a "predicate decomposition".
