Web 3.0

Web 3.0 is one of the terms used to describe the evolutionary stage of the Web that follows Web 2.0. The term "Web 3.0" has been introduced to hypothesize about a future wave of Internet innovation. Views on the next stage of the World Wide Web's evolution vary greatly, from the concept of emerging technologies such as the Semantic Web, ubiquitous connectivity, network computing, Distributed Databases,Intelligent Applications and advances in computer graphics will play the key role in the evolution of the World Wide Web.Web 3.0 has been described as the "executable web".

Network Computing :

Web 3.0 could be the realization and extension of the Semantic web concept. Semantic web is materialized by improving the principles of knowledge representation from Artificial Intelligence.Web 3.0 has also been linked to a possible convergence of Service-oriented architecture and the Semantic web.Web 3.0 is also called the "Internet of Services".

Distributed Databases :

Web 3.0 is the emergence of "The Data Web" as structured data records are published to the Web in reusable and remotely queryable formats, such as XML, RDF, Website Parse Template and microformats.

The recent growth of SPARQL(Simple Protocol and RDF Query Language.) technology provides a standardized query language and API for searching across distributed RDF(RESOURCE DESCRIPTION FRAMEWORK) databases on the Web. The Data Web enables a new level of data integration and application interoperability, making data as openly accessible and linkable as Web pages

Intelligent Appliations :

Web 3.0 has also been used to describe an evolutionary path for the Web that leads to artificial intelligence that can reason about the Web in a quasi-human fashion. The companies are implementing new technologies that are yielding surprising informations about latest market trends and most searched topics etc.. from mining information on Web sites.
