Web 3.0 - What is Web 3.0

Word Wide Web Evaluation 
We all might have listen about Web 2.0 and Web 3.0. Today I googled these terms and found some facts ,which I would like to share.
According to Wikipedia, an online encyclopedia, “Web 3.0 is a third generation of Internet based  Web Service, which emphasize machine-facilitated understanding of information in order to provide a more productive and intuitive user experience.”. The third generation of Internet services is collectively consists of semantic web, micro-formats  natural language search, data-mining, machine learning, recommendation agents that is known as Artificial Intelligence technologies or Intelligent Web.
Web 3.0 is a specification not any specific technology, sometimes it is referred to as a Semantic Web.Semantic WebWeb 3.0 is an  extension of the World Wide Web in which web content can be expressed not only in natural language, but also in a form that can be understood, interpreted and used by software agents, thus permitting them to find, share and integrate information more easily.
As per scientific article written by American Coauthored Berners-Lee Semantic Web described this term as a place where machines can read Web pages as much as humans read them e.g. web connected bathroom mirrors, which can read the news coming through on the web.
Web 3.0 include transforming the Web into a database, a move towards making content accessible by multiple non-browser applications, the leveraging of artificial intelligence technologies, the Semantic web, or the Geo-spatial Web.
Steve, a famous Blog author has defined the term Web 3.0 as, “Web 3.0 is highly specialized information structures, moderated by a group of personality, validated by the community, and put into context with the inclusion of meta-data through widgets”.
How Stuff works a good website has also defined the term Web 3.0 -- It will make tasks like your search for movies and food faster and easier. Instead of multiple searches, you might type a complex sentence or two in your Web 3.0 browser, and the Web will do the rest. In our example, you could type "I want to see a funny movie and then eat at a good Mexican restaurant. What are my options?" The Web 3.0 browser will analyze your response, search the Internet for all possible answers, and then organize the results for you.Its mean that you do not to search so much on internet what you need with some specific key words.
As per labnol.org below are differences between Web 1.0 ,Web 2.0 and Web 3.0.
Web 1.0 – That Geocities & Hotmail era was all about read-only content and static HTML websites. People preferred navigating the web through link directories of Yahoo! and dmoz.
Web 2.0 – This is about user-generated content and the read-write web. People are consuming as well as contributing information through blogs or sites like Flickr, YouTube, Digg, etc. The line dividing a consumer and content publisher is increasingly getting blurred in the Web 2.0 era.
Web 3.0 – This will be about semantic web (or the meaning of data),  personalization  (e.g. iGoogle), intelligent search and behavioral advertising among other things.
