Web 1.0 and Web 2.0 and
Let me first give the descriptions of
these technologies by the help of Wiki.
Web 3.0?
Web 1.0 :
Socially,
users can only view webpages but cannot reflect on the content of the
webpages.
Technically, web 1.0 webpage’s
information is closed to external editing. Thus, information is not
dynamic and updated only once in a while by the webmaster.
Web 2.0:
It is actually what we have today.
A Web 2.0 site allows users to interact
and collaborate with each other in a social
media. Examples of Web 2.0 include social
networking sites, blogs,
wikis, video
sharing sites, hosted
services, web
applications, mashups
and folksonomies.
Web 3.0 (Semantic Web)
I highly recommend you to watch this video to get insight of Web3.0
According to the W3C, "The
Semantic Web provides a common framework that allows data to be
shared and reused across application, enterprise, and community
boundaries."
It means that different system will be
able talk to each other. Today it is not possible. Let me give you a
simple example; if you would like to Google the restaurants near to
your location that are open during the weekend, you need to basically
make multiple queries to reach a conclusion. You might first need to
find the list of restaurants near to you, then you need to check
their opening hours etc and then maybe make a reservation. Instead
of doing such operations, would not it be nice if we just type “show
me available restaurants that are open and … “ . With
SemanticWeb, it is possible for example to let different websites
share a common source and benefit from it.
Briefly the purpose of Web 3.0
(Semantic Web) is driving the evolution of the current Web by
enabling users to find, share, and combine information more easily.
Humans are capable of using the Web to carry out tasks such as
finding the Irish
word for "folder", reserving a library book, and searching
for the lowest price for a DVD. However, machines
cannot accomplish all of these tasks without human direction, because
web pages are designed to be read by people, not machines. The
semantic web is a vision of information that can be readily
interpreted by machines, so machines can perform more of the tedious
work involved in finding, combining, and acting upon information on
the web.
Tim
Berners-Lee originally expressed the vision of the Semantic Web as
follows:[12]
I have a dream for the Web [in which computers] become capable of analyzing all the data on the Web – the content, links, and transactions between people and computers. A ‘Semantic Web’, which should make this possible, has yet to emerge, but when it does, the day-to-day mechanisms of trade, bureaucracy and our daily lives will be handled by machines talking to machines. The ‘intelligent agents’ people have touted for ages will finally materialize.
