google’s got images, but don’t expect miracles:
“If people know the name of the picture or of the video, then, yes, we can find it. But if people just say, “There was this video of a woman on the beach running into the water,” that’s hard. The image-understanding technology is not so far [along] yet.”
i could see something like rdfpic being useful for google – except for the little problem that nobody is exactly beating a path to the whole embedding-semantics-in-images way of thinking.
