Re the discussion below, while Google doesn't, Clusty makes a basic stab. See http://clusty.com/
When I do a search with Google I see very little 'intelligence' of that kind in the results. There appears to be some statistical weighting, but the 'intelligence' of the results seems to depend entirely on whether my word combination captures the concept I'm looking for. I don't believe that's definable by any means I know of yet.
Yes. As far as I'm aware Google has not yet deployed a production quality technology for the semantic web. Google doesn't reason about concepts. Not only can't it trim down logically inappropriate results, it can't expand on related concepts unless there happens to be data (like from Wikipedia) where someone has created a document that physically contains the overlap of different nomenclatures. It certainly can't tell you whether two mathematical formulations of similar models will make the same predictions unless, again, there happens to be a web page posting of someone that said it was so. -- George T.
