THE TERM WEB 3.0 FIRST APPEARED IN EARLY2006 IN A BLOG ARTICLE BY JEFFREY ZELDMANCRITICAL OF WEB 2.0 AND ASSOCIATED

TECNOLOGIES SUCH AS AJAX.

MAY 2006 TIM BERNERS LEE.- on web 2.0 everything looked misty but access to a

semantic web integrated across a huge space of data andhave access to an unbelievable data resource.

NOV 2006 JERRY YANG FOUNDER & CHIEF OF YAHOO.-net reached critical mass as richer devices and richer

ways of interacting with network ,not only on hardware

Web 1.0 : Web Browser driven "Interactive Web of Hypertext" pages where presentation, logic, anddata are indistinguishable

Web 2.0 : Web Services based API driven "Web of services" that separate " Application Logic " fromthe intermingled presentation, logic, and datapages of Web 1.0 . Examples of Web 2.0 application profiles include: the use of Ajax . Web2.0 does not explicitly expose Data Models .

First we download the web pages from theweb .

Then embedded the semantic information into

themIt consist of two parts

1.The web information between rdf_discription& /rdf_discription

2.The information between ontopath &/ontopath
