Web 3.0. — Using the same pattern as the above Wikipedia definition, Web 3.0 could be defined as: “Web 3.0, a phrase coined by John Markoff of the New York Times in 2006, refers to a supposed third generation of Internet-based services that collectively comprise what might be called “the intelligent Web” — such as those using semantic web, microformats, natural language search, data-mining, machine learning, recommendation agents, and artificial intelligence technologies – which emphasize machine-facilitated understanding of information in order to provide a more productive and intuitive user experience.”
Web 3.0 Expanded Definition. I propose expanding the above definition of Web 3.0 to be a bit more inclusive. There are actually several major technology trends that are about to reach a new level of maturity at the same time. The simultaneous maturity of these trends is mutually reinforcing, and collectively they will drive the third-generation Web.
