The semantic web is an evolving development of the Web in which the meaning of information and services on the web is defined, making it possible for the web to "understand" and satisfy the requests of people and machines to use the web content. It derives from World Wide Web Consortium director Sir Tim Berners-Lee vision of the Web as a universal medium for data, information, and knowledge exchange.
At its core, the semantic web comprises a set of design principles, collaborative working groups, and a variety of enabling technologies. Some elements of the semantic web are expressed as prospective future possibilities that are yet to be implemented or realized. Other elements of the semantic web are expressed in formal specifications. Some of these include Resource Description Framework (RDF), a variety of data interchange formats and notations such as RDF Schema (RDFS) and to Web ontology language, all of which are intended to provide a formal description of concepts, terms and relationships within a given knowledge domain.
Where Web 2.0 is focused on people, the Semantic Web is focused on machines. The Web requires a human operator, using computer systems to perform the tasks required to find, search and aggregate its information. It's impossible for a computer to do these tasks without human guidance because Web pages are specifically designed for human readers. The Semantic Web is a project that aims to change that by presenting Web page data in such a way that it is understood by computers, enabling machines to do the searching, aggregating and combining of the Web's information — without a human operator.
