The document discusses the evolution of the World Wide Web towards the Semantic Web, highlighting its potential to enhance information retrieval and usability for users. It explains the limitations of the current web, specifically Web 2.0, and emphasizes the importance of semantics over mere syntax in creating a more meaningful and machine-readable internet. The Semantic Web aims to facilitate better understanding and relationship recognition between data, ultimately improving search efficiency and personalization.

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.
