The mantra of the information age has been “The more information the better!” But what happens when we search the web and get so much information that we can’t sort through it, let alone evaluate it? Enter the semantic web, or Web 3.0. Among other things, the semantic web makes information more meaningful to people by making it more understandable to machines.
Consider a simple example. If you want to know my mailing address, currently you need to go to my web page and root around until you find it. That’s because the current coding system used to build web pages, largely HTML, displays information without identifying it in any meaningful way. That is, my address is not coded as “an address,” it is simply presented as a series of characters on the screen. Contrast this with a database about your friends that contains a specific column called “mailing address.” Even if your database included millions of entries, locating my address is easy.
