What is the Semantic Web? The Semantic Web is an extension of the current Web that will allow you to find, share, and combine information more easily.

The Semantic Web - The original web realized The original proposal of the WWW from 1989 included a figure showing how information about a Web of relationships among named objects could unify a number of information management tasks.
