Web 3.0 is a term, which definition is not confirmed or defined so far as several experts have given several meaning, which do not match to each other, but sometimes it is referred to as a Semantic Web. In the context of Semantic Web, Web 3.0 is an evolving 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.

Tim Berners-Lee, the inventor of first World Wide Web has coined the term Semantic Web. But the concept of Web 3.0, first entered among the public in 2001, when a story appeared in scientific article written by American Coauthored Berners-Lee that 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.

There are several definitions of the web, but usually Web 3.0 is defined as a term, which has been coined with different meanings to describe the evolution of web usage and interaction among the several separate paths. These 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 Geospatial Web.

According to Wikipedia, an online encyclopedia, “Web 3.0 is a third generation of Internet based Web services, 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, microformats, natural language search, data-mining, machine learning, recommendation agents that is known as Artificial Intelligence technologies or Intelligent Web.

According to some experts, “Web 3.0 is characterized and fueled by the successful marriage of artificial intelligence and the web”. While some experts have summarized the definition defining as “Web 3.0 is the next step in the progression of the tubes that are the Internets”.

According to Nova Spivack, the CEO of Radar Networks, one of the leading voices of this new-age Internet, “Web 3.0 is a set of standards that turns the Web into one big database.”

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”.

While Leiki, the Finland based pioneer company of Semantic Web describes: “Web 3.0 makes the discovery of content streams effortless. It introduces automatic discovery of like-minded users and automatic tagging.”
