The document discusses the evolution of the World Wide Web from Web 1.0 to Web 3.0. Web 1.0 focused on static, read-only pages and basic hyperlinking. Web 2.0 enabled user-generated content and social networking. Web 3.0 aims to make the web more intelligent through semantic annotation and artificial intelligence to better understand user needs. It also discusses some key applications and limitations of each stage of the web's development.

1.  The world wide web is larger
collection of interconnected
Documents or Content.
 Facilitates communication between
people and also computers.
 Web based on Hypertext.
 Also based on client/server model
 The Internet is the collection of
interconnected computer Networks.
World Wide Web ≠ Internet Service
We must remember that both are not the same.
Web is different then Internet.
WEB INTERNET

2. WEB 1.0
(Past)
WEB 2.0
(Present)
WEB 3.0
(Future)
Web 1.0 was referred as the first
generation of World Wide Web
which was basically defined as-
“It is an information space in
which the items of interest
referred to as resources are
identified by global identifier
called as Uniform Resources
Identifiers (URIs)”.
 First stage of the World Wide
linking web pages and
hyperlink
 Most read-only Web. It
focused on companies home
pages
 Dividing the world wide web
into usable directories
 It means Web is use as
“Information Portal”.
 Everyone has their personal
own little corner in the
cyberspace
 It started with the simple idea
Tim O’Reilly defines web 2.0 on his
website as follows-
“Web 2.0 is the business revolution
in the computer industry caused by
the move to the internet as
platform, and an attempt to
understand the rules for success on
that new platform. Chief among
those rules is this: Build
applications that harness network
effects to get better the more
people use them.”
 It is a platform that gives users
 the possibility (liberty) to control
 their data.
 This is about user-generated
 content and the read-write web.
 People are consuming as well
 as contributing information
 through blogs or sites like
 Flicker, YouTube, Digg, etc.
Web 3.0 is one of modern and
evolutionary topics
associated with the following
initiatives of Web 2.0. Web
3.0 was first coined by John Markoff
of the New York Times and he
suggested web 3.0 as third
generation of the web in 2006. Web
3.0 can be also stated as-
“executable Web”.
 Semantic Web
• It is a Web of data.
• changing the web into a
language that can be read and
categorized by the system rather
then humans.
• An idea of more meaningful web
where resource discovery will be
assisted by intelligent agents.
 Artificial Intelligence
• Extracting meaning from the
way people interact with the
web.

3. Generations of WEB 1.0
Content
• Personal websites.
• Content destination sites.
Search
• Critical mass of content drives need for search
engines.
Commerce
• Commerce goes Mainstream.
• Digital goods rise.

4. Generations of WEB
2.0
 Speedy
• More timely information.
• More efficient tools to find information.
 Collaborative
• At the same time in different places.
 Trust-worthy
• Users establish trust Networks.
• Government use the Web

5. Generations of WEB
3.0
 Ubiquitous
Available anytime, anywhere, through any channel or device.
 Individualized
Filtered and shared by friends or trust networks.
 Efficient
Relevant and contextual information findable instantly.

7. Limitations-
The major limitations of Web 1.0 are as follow:-
• The Web 1.0 pages can only be understood by humans (web readers) they do not
have machine compatible content.
• The web master is solely responsible for updating users and managing the content
of website.
• Lack of Dynamic representation i.e., to acquire only static information, no web
console were available to performing dynamic events.
The major limitations of Web 2.0 are as follow:-
• Constant iteration cycle of Change and Updates to services.
• Ethical issues concerning build and usage of Web 2.0.
• Interconnectivity and knowledge sharing between platforms across community
boundaries are still limited.
The major limitations of Web 3.0 are as follow:-
• Vastness: The World Wide Web contains many billions of pages. Redundancy in Data
may occur which has not yet been able to eliminate all semantically duplicated
terms.
• Vagueness: This arises from the vagueness of user queries, of concepts represented
by content providers, of matching query terms to provider terms and of trying to
combine different knowledge bases with overlapping but subtly different concepts.
• Deceit: This is when the producer of the information is intentionally misleading the
consumer of the information.

8.  Types of WEB 1.0 applications are:-
• static web sites
• personal sites.
 Types of Web 2.0 applications are:-
• Collaborative Web Tools –Wikipedia, Drupal, Joomla,
Blog, Trac, Bugzilla etc.
• Interactive Web Tools – Gtalk, Yahoo Chat, GoogleDoc,
Picasa, Flickr
• Social Networking Tools- Orkut, Facebook, Twitter,
WhatsApp etc.
• Information Mashup – Google Map, Indiarailinfo, etc.
Types of Web 2.5 applications are:-
• Amazon
• Google
Types of Web 3.0 applications are:-
• Apple’s Siri
• Google Cloud API

9. Four design essentials of a Web 1.0 site include:
 Static pages.
 Content is served from the server’s file-system.
 Pages built using Server Side Includes or Common Gateway Interface (CGI).
 Frames and Tables used to position and align the elements on a page.

10. Development of Web 2.0 technologies:-
 Users’ Participation
A user can express their feelings and view about the content.
They can agree or disagree with the source. This participation leads in collaboration
and development of innovative thoughts.
 User centric services
The user may keep changing their priorities and services options and the services have
to stand themselves to each call of their users.
 Decentralization and Interoperability
The service nodes generate services in a standard format, which can be amalgamated
to a single service. This makes systems interoperable over a federated environment.
 Hiding technological complexity
The technology is developed in such a way that users need not bother about the hassles
of technology rather they should concentrate on content of the services. The technology
is kept hidden from the user.
 Modularity
Modules are components of any system. Modular approach towards a system provides
flexibility for adding or removing any feature out of the system. In Web 2.0, the
modularity provides facility to add or remove components offering flexibility to a great
extent.

11. Key Elements of Web 3.0
 Semantic Web
The succeeding evolution of the Web involves the Semantic Web. The semantic web
improves web technologies in demand to create, share and connect content
through search and analysis based on the capability to comprehend the meaning of
words, rather than on keywords or numbers.
 Artificial Intelligence
Combining this capability with natural language processing, in Web 3.0, computers
can distinguish information like humans in order to provide faster and more
relevant results. They become more intelligent to fulfil the requirements of users.
 3D Graphics
The three-dimensional design is being used widely in websites and services in Web
3.0. Museum guides, computer games, ecommerce, geospatial contexts, etc. are all
examples that use 3D graphics.
 Connectivity
With Web 3.0, information is more connected thanks to semantic metadata. As a
result, the user experience evolves to another level of connectivity that leverages all
the available information.
 The Media Centric Web
According to media centric web approach ,in near future search engines are able to
take media
such as audio, video, image etc as an input element and be able to search for
similar media

12. Conclusion
The web offers so many opportunities to people with disabilities that are
unavailable through any other medium. It offers independence and
freedom. However, if a web site is not created with web accessibility in
mind, it may exclude a segment of the population that stands to gain the
most from the internet.
The Semantic Web (Web 3.0) promises to “organize the world’s
information” in a dramatically more logical way than Google can ever
achieve with their current engine design.
o knowledge of all kinds gets represented in a form that is interpretable
both by people and machines.
o different forms of language in which knowledge is expressed begin to
be interrelated and made interchangeable with each other.
o when knowledge is encoded in a semantic form, it becomes transparent
and accessible at any time to a variety of reasoning engines.
