Web 3.0Presentation on

by Veena Hegde


The “World Wide Web” concept was designed in 1989 by Tim Berners-Lee and scientists at CERN (Geneva), the European centre for High Energy Physics, who were interested in making easier to retrieve research documentation.

A year later he had developed a 'browser/editor' program and had coined the name World Wide Web as a name for the program.

In 1991 the World Wide Web was released to the public.

The early web allowed us to search for information and read it.

This first implementation or the first generation of the web represents the Web 1.0, which, according to Tim Berners-Lee, could be considered the “Read-only Web.“

This generation of Web allowed the user to search for information and read it. There was no scope for user interaction or content contribution.

Presentation on Web 3.0


Web 2.0The present generation of the Web or the second generation of the Web is known as Web 2.0

If we stick to Tim Berners-Lee’s method of description, we can call this the Read-Write Web.

This generation of Web allows the user to contribute content and interact with other Web users.

Web 2.0 is the movement towards the Social Web with user generated and user driven contents.

This is the generation of Blogs, Wikis, Tagging, etc.



Web 3.0 - Introduction


The next generation of Web will see a maturity of Web 2.0

By extending Tim Berners-Lee’s description, we can call this the Read-Write-Execute Web.

Web 3.0 is a term that has been coined with different meanings to describe the evolution of Web usage and interaction along several separate paths.

People will see the Web becoming smarter with some reasoning capabilities built into it.

There is considerable debate as to what Web 3.0 means and what a suitable definition might be. But here are a few possibilities:

The Semantic WebThe Media-Centric WebThe 3D WebThe Pervasive Web


Web 3.0 - What Web 3.0 could possibly be: The Semantic Web


When we need to browse data on the website, we use a search engine that gives the search results in the form of a list.

We need to click on one of the items from the list and see what it really means and whether it is really related to what we are looking for because the list may contain unrelated and irrelevant data along with what we are looking for.

Inspite of tagging, if the names are not precisely identified, the result would not always be what we are really looking for.

Or, for example, we need to find lowest price for a flat screen TV larger than 40 inches with a 1080p resolution at stores in the nearest locality that are open till a specific time.

Today, this task cannot be accomplished without our directions because the Web pages are designed to be read by people and not machines.




This is where the Semantic Web Technology comes into picture.

In the Semantic Web environment, we could use a Semantic Web agent to search for the required information and the results of the search will be precise and relevant.

Semantic Web is a Web of data that can be processed by machines.

It is a Web where machines can read sites ALMOST as easily as humans read them.

The vision of Semantic Web is to allow data to be processed automatically by tools or software agents, thus letting them find, share and integrate information more easily, making the Web a universal medium for information exchange.

The technology of the Semantic Web can be said to be the technology of precise vocabularies.




Sematic Web does not contain artificial intelligence.

It relies on structured sets of information and certain inference rules that helps it to ‘understand’ the relationship between different data resources.

So it only means that the computer does not understand the relations the way we humans understand, but it has enough information to make logical connections and decisions.

This is made possible by the use of certain semantic technologies likeURI or the Universal Resource Identifier - a global naming scheme for the

data/resource.RDF or the Resource Description Framework - a standard syntax for describing

the data that has been named using the URIRDFS or the Resource Description Framework Schema - creates the properties

for the resourcesOWL or the Web Ontology Language - describes the types of relationship

between data items.


Web 3.0 - What Web 3.0 could possibly be: The Media-Centric Web


Today, when we search for images, video or songs, we depend on keywords.

For a given image search, the search engine turns up countless images which includes many unrelated images, even as it misses out on many that may have been a perfect match.

The situation is much the same for sound files.

This is where the Media-Centric Web comes into Picture.

Media-Centric Web is where you find a media using a media, not just keywords.

I supply an image of my favorite celebrity and the search engine turns up a hundred similar images.

A few services have already taken the first steps in this direction.


Web 3.0 - What Web 3.0 could possibly be: The Media-Centric Web


There are new photo sharing / visual search engines that can be used to find similar faces and objects from a vast numbers of images on the Web.

The results can also be refined using color, shapes and textures.

The system can also be trained to recognize faces and automatically tag the pictures.

Such services have key features likeSearch images by image instead of text.Find items with specific features that you like.Find color variants of the items you like.Ability to upload your own images of an item and find similar items.Ability to search for more photos of the same person across the Internet.Automatically sort online images by people appearing in them.Find people matching specific looks on Social networking.


Web 3.0 - What Web 3.0 could possibly be: The 3D Web


3D refers to the three dimensional design that represents the look of an object from three different planes.

3D Technology is slowly catching up on the web.

Microsoft is coming up with a Technology which will take a collection of images, analyze them for similarities and displays them in reconstructed 3D space.

This system will allow users to walk or fly through a scene to view photos from any angle.

This system builds a 3D model from a raw collection of photos.

The first users of this system could be the photo-sharing websites.

The other use would be for property and tourism where a virtual tour could be provided for the potential visitors.

Microsoft says that the technology will certainly be web based.


Web 3.0 - What Web 3.0 could possibly be: The Pervasive Web


Pervasive Web is a vision which refers to the uses of the Web everywhere, note just on PCs.

It could be on the cell phone, on jewellery.

A web that is spread throughout the home and office

For example, a web-based window that checks the weather and opens it or closes it based on the weather.

This may not happen in the near future but this is one of the visions.


Web 3.0 - What Web 3.0 could possibly be: Conclusion


Web 3.0 is all about creating a richer, more meaningful language for computers to use in communicating with other computers over the Net.

Its is all about getting the machines to do a lot of the interpretive functions that are currently being done by people.

Web 3.0 is the next generation of the Web which would probably take automation to a whole new level.

Maybe that is what Web 3.0 going to be.
