The problem of syntactic ambiguity is AI-complete if you treat ambiguity as a Boolean problem in which the only possible solutions are precise. This leads me to the problem with the ancient belief that weighted methods (including Bayesian and other probability methods) were - in themselves - solutions to AGI complexity. It should be obvious that weighted reasoning is not in itself sufficient to distinguish between imperfect solutions just because it used partial valuations. Discreet collections are necessary for the discovery of reasons (including reasons based on the finding of correlated instances) which might be used in the discovery of special cases or other major branches of cases. The argument of equivalence is not truly relevant here because it is the value of the collection that comes bearing the potential of a possible solution process. In particular those sub-categorizations of the collections which have some relevant structural relations (like analogy or similarity and reasons) can point to a way to find other good solution even though it might be imperfect in some other way.
