The document discusses the evolution of the World Wide Web from Web 1.0 to Web 2.0. It explains that Web 2.0 focuses on user-generated content through blogs, wikis, tagging, and multimedia sharing. Key characteristics of Web 2.0 include harnessing collective intelligence through user contributions, generating and using large-scale data, and the architecture of participation where users contribute through reviews and on platforms. The document also explores how Web 2.0 technologies can be used for teaching and learning, scholarly research, and academic publishing.

2. Introduction
• In 2006, Time Magazine’s Person of
the Year ‘YOU’
• A new improved second version of
the Web
• He explains the content

3. • “Web 2.0’ for you is blogs and wikis, then that is
people to people” - Sir Tim Berners-Lee (inventor of
the Web)
• To understand Tim’s attitude we must read his book
‘Weaving the Web’(1996)
• Web 2.0’ was officially coined in 2004 by Dale
Dougherty, a vice president of O’Reilly Media Inc.
• The companies that had survived the dot-com
firestorms of the late 90’s now appeared to be the
stronger and have a number of things in common.
• Web 2.0’ is more fully implemented web

4. • Number of web based services blogs, wikis, multimedia
sharing services, content syndication, podcasting and
content tagging services.
• They are just improved everytime
• Blogs- coined by Jorn Barger in1997 and it refers to a
simple webpage consists brief paragraphs. Now(vlogs)
• Wikis
• Tagging
• Multimedia sharing
• Audio blogging and podcasting
• RSS syndication

5. • Individual production and User generated content “I
can do that”
• Harnessing the power of the crowd (wisdom of crowds)
‘the collective intelligence’
• Generating and making use of data in a large scale
(Google)
• Architechture of Participation – It is the participants
who contribute through reviews and platform.
Eg.Torrent, Google search
• Network effects –lock into technologies (Microsoft,
Office)
• Robert Metcalfe’s Law. Growth in the value of
telecommunications netword depends on the number
of users

6. • What shape is the web? Argues the Metcalfe’s law
• Proposes a Long tail – the network effect is
proportional to n log(n) rather than n2
• The long tail is the title of the book by Chris Anderson
where he argues the economic and social implications
affects web.

7. • Web as the Platform – number of softwares needed a
platform like Mac OS, Windows to run. Now Web
became such a platform.
• Ajax- Asynchronous Javascript + XML- term coined by
Jesse James Garrett- technology used to deliver Web
2.0’ over the old HTML
• Web architecture debate
• Microformats – used to embed semi-structured
semantic information (eg. Firefox)
• Open APIs- Application Programming Interface (google
maps API- which allows web developers to embed maps
in their own sites.)

8. • There is advantage and disadvantage of incorporating
social software into mainstream education
• Teaching and learning- remote access, experiments,
• Privacy and plagiarism is a question
• Scholarly Research – tagging and blogs help researcher
• Academic Publishing – Web is the first stage of
publishing with open access at once
• Libraries and archiving – technology provided space to
preserve and serve data
• It also saved the access and reviews of the public
• Web2.0 services and characteristics with respect to
archiving is explained through a table.

9. • Semantic- more personalised
• Web science field will start
• Web as platform – Your computer as a server
• Trust, Privacy, Security and social networks – Web
would work as automatic filter
• Web 3.0 – artificial intelligence, paid for logging in. ???
