Once upon a time, search was the greatest thing since sliced bread. Most of us still couldn’t live without it, but hardly an hour goes by that we aren’t cursing the lousy results from our otherwise favorite search engine. Queries which seem straightforward to us stump even the mighty Google, despite the billions of dollars invested in it. So the amazing show put on by IBM’s Jeopardy-winning Watson was inspiring as a possible model for how we’d like to see our own questions answered. Unfortunately, we can’t all have our own Watson — at least not anytime soon — but the internet industry is trying to help us get similar results using semantic search, building on a much broader set of technologies loosely called the semantic web.
