Web 3.o is referred as intelligent web or third generation of internet based services.  The term was coined by John Markoff in 2006. He explained “There is no easy consensus about how to define what is meant by Web 3.0, but it is generally seen as a reference to the semantic Web. While it is not that much more precise a phrase, the semantic Web refers to technology to make using the Internet better by understanding the meaning of what people are doing, not just the way pages link to each other.”

Web 3.0 is supposed to be more connected and intelligent  with major emerging technology trends like semantic web, data mining, machine learning, natural language processing, artificial intelligence and other such technologies focused on information which is machine facilitated. So Web 3.0 is the idea of such a web that will store information in such a way that computers and other devices will understand on their own.

FB app and Google Voice search, Apple’s Siri are some of the examples of web 3.o usage.

The web as a whole can be designed more intelligently around serving a user’s wants or needs. The developers and authors, singly or in collaboration, can use self-descriptions or similar techniques so that the information provided by the new context-aware program is relevant to the user.
