There's also the locality aspect of the problem which is unaddressed. Typically humans resolve ambiguity in a finite namespace. E.g. there are only a few Bob's I know of. If a single human were asked to resolve of a bob without context it would be a hard to resolve problem. I think all naming resolution problem are related to identification on the basis of attributes, and a url in a certain sense is supposed to model enough attributes to help us resolve this. We have modeled systems unlike humans, not with distributed and local information but looking at url resolution using a central brain of sorts.
