Q: Can you give me an example?
A: Say you're looking for a photograph in a certain state. And you have another photograph somewhere with a ZIP code. The machine understands that we're talking about location, and a Semantic Web search engine could actually go out and learn, find the logic on the Web, and then know that when something is in a given ZIP code, it's also in a given state. So, a search by state would also be able to find things categorized by ZIP code.
