Part of the reason that the Google/Autonomy route is more successfuly right now is that it relies on heuristics to extract semantic bits out of a very, very messy web. Heuristics can take you only so far. RDF et al., on the other hand, requires that the web be clean to start with. But this requires a lot of up-front work. Once heuristics hit their practical limits, Google will only be able to go further if the web becomes a bit more clean. (After all, my current "desktop filing system" can only take me so far. Eventually, if I want to keep finding the things I need, I had better start organizing this stuff). Conversely, strict adherence to RDF will only contribute to the SW's lack of success. The RDF-based SW will have to loosen its necktie and relax a bit if it's going to go further (or at least learn to live side-by-side with the non-RDF world), just as Google will have to start paying more attention to the more formalized SW metadata. And, as a result, this sort of vulcan mind-meld of RDF and Google you speak of does look likely. I would even go so far as to say that it's the only real possbility... --- Seairth Jacobs seairth@s...
