3.  A PROPOSED DEVELOPMENT OF WORLD WIDE
WEB

4.  Web
 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
Semantics is related to the word “syntax”.
BUT
Syntax is how to say something and semantics is the
meaning behind what you say.

6.  Web 2.0
 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 etc.

7.  Today’s scenario of
web.......
 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.  Limitations of the
web search today
 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.  Reason behind searching
an alternative of web 2.0
 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 Semantic Web is all about.

10.  The Semantic Web
“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. Semantic web
includes…

13.  Working
 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 .

14.  AN EXAMPLE TO
UNDERSTAND THE
SEMANTIC WEB
 Suppose, you want to watch a movie and grab something
to eat.
 You like an Action movie and Italian food.
 Now , you perform a search for movie theaters , and
restaurants .
 In this phenomenon , you spend half an hour doing the
planning .
 THIS IS HOW THINGS WORK TODAY.
 The next generation of the web will change How things
work .

15. …………
Semantic web will make search task faster and easier by
making searches more personalized.
AS:
You could enter ” I want to watch an action movie and then
want to have a dinner at an Italian Restaurant . ”
And , the semantic web will display the results for you.
The Semantic web will act as a Personal Assistant.

16. Advantages
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 .

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