Imagine you were suffering from a bad case of tennis elbow and wanted to find a doctor who could see you on Saturday. A simple Google search for “doctors” would find some referral services, but it would also produce pages of doctor jokes and medical associations. More significantly, you’d miss all kinds of “physicians” and “therapists” who might be able to help, simply because you didn’t choose that word. Search on “tennis elbow” and you’re not going to find help for “athletic injuries.” And searching for offices that are “open Saturdays” won’t help you find the ones with “weekend hours.”

To solve that problem, we need a search system that doesn’t just process and parse our language, but understands it; programs that don’t just match your search terms but intuitively recognize context to deliver what you’re really looking for. Fortunately, engineers and researchers around the world are already at work to bring about this system, and they call it the semantic Web.
