SEMANTIC WEB :
Web in which the meaning (semantics) 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.
At its core, the semantic web comprises a set of design principle.
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 (e.g. RDF/XML) and notations
such as RDF Schema (RDFS) and the Web Ontology Language
(OWL), all of which are intended to provide a formal description of
concepts, terms, and relationships within a given knowledge.
