The Semantic Web is an evolving development of the World Wide Web in which the word semantic stands for the meaning of. The semantic of something is the meaning of something. The Semantic Web or Web 2.0 or Web3.0 is a “Web of data” that enables machines to understand the semantics or meaning. Of information on the World Wide Web. It extends the network of hyperlinked human-readable web pages by inserting machine-readable metadata about pages and how they are related to each other. Enabling automated agents to access the Web more intelligently and perform tasks on behalf of users. The term was coined by Tim Beemers-Lee, the inventor of the World Wide Web and director of the World Wide Web Consortium. Which oversees the development of the proposal Semantic Web standards? He defines the Semantic Web as “a web of data that can be processed directly and indirectly by machines.”

3. INTRODUCTION
 A PROPOSED DEVELOPMENT OF WORLD WIDE
WEB

4.  The Web is a system of interlinked documents accessed via
the internet.
 Computers use network protocols to communicate in
networks.
 Web browsers use HTTP to communicate with Web servers.

5. Semantics is related to the word “syntax”.
BUT
Syntax s how to say something and semantics is
the meaning behind what you say

6. Web 2.0 :-
Web 2.0 describes World Wide Web websites
that emphasize user-generated content and
usability (ease of use, even by non-experts) for
end users.
Example:- You Tube, social networking sites such
as facebook, twitter, instagram etc.

7.  Most of the Web content is suitable for
human use.
 Information seeking, publishing, and using,
searching for people and products, shopping,
reviewing catalogues, etc.
 Dynamic pages generated based on
information from databases but without
original information structure found in
databases.

8. • The Web search results are high recall, low
precision.
• Results are highly sensitive to vocabulary.
• Results are single Web pages.
• Most of the publishing contents are not
structured to allow logical reasoning and
query answering.

9.  In web 2.0, web pages are written in HTML. HTML
describes the syntax not the semantics.
 If computer can understand the meaning behind
information.......
 They can learn what we are interested in.......
 They can help us better find what we want.......
AND
 This is really what the Semantics Web is all about.

10. “The Semantic Web is an extension
of the current web in which
information is
given well defined meaning,
better enabling computers and
people to
work in co-operation.”

11. ............
Today’s web is about documents but semantic
web is about things.
It can recognize people , places , events ,
companies , products , movies , etc. It can
understand the relationships between things.

12. The Semantic web proposes to help
computers “read” and use the web. The big
idea is pretty simple –Metadata added to web
pages can make the existing World Wide Web
machine readable. This won’t make
computers self-aware, but it will give
machines tools to find, exchange and, to a
limited extent, interpret information.

17. Semantic web will make search tasks faster
and easier.
Semantic web will make searches, more
personalized.
Semantic web browser will act as a personal
assistant.

18. The Semantic Web is an initiative that aims at
improving the current state of the World Wide
Web.
