INTRODUCT

ION

A PROPOSED DEVELOPMENT OF WORLD WIDE WEB

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.

Semantics

Semantics is related to the word “syntax”.

BUT

Syntax is how to say something and semantics is the meaning behind what you say.

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.

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.

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.

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.

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.“

…………

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 .

Semantic web includes…

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 .

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 .

…………

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.

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 .

Conclusion

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