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.

Web 2.0
The 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
Presentation on Web 3.0
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 Web
The Media-Centric Web
The 3D Web
The Pervasive Web

Web 3.0 - What Web 3.0 could possibly be: The Semantic Web
Presentation on Web 3.0
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.

Web 3.0 - What Web 3.0 could possibly be: The Semantic Web
Presentation on Web 3.0
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.

Web 3.0 - What Web 3.0 could possibly be: The Semantic Web
Presentation on Web 3.0
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 like
URI 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 URI
RDFS or the Resource Description Framework Schema - creates the properties
for the resources
OWL 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
Presentation on Web 3.0
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
Presentation on Web 3.0
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 like
Search 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
Presentation on Web 3.0
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
Presentation on Web 3.0
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
Presentation on Web 3.0
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.
