Who?
The usual suspects
Computer industries
Information industries
Those who use/are

Human activities,

Human creations
Human institutions
6. Let’s break it down…
Key concepts:
Individual production & user-generated content
Harnessing the power of the crowd
Data on an epic scale
Architecture of participation
Network effects
Openness
-- Dr. Linda Main, SJSU-SLIS, LIBR 246-15 class, Fall 2007
7. Let’s break it down…
In sum, Web 2.0 is online…
…collaboration
…contribution
…community
Focus is on the user
Read-and-Write Web – Web as Platform
8. Individual Production &
User-Generated Content
Rising model of information production-
dissemination-consumption cycle
2-way / multi-way conversation2-way / multi-way conversation
Questions who has authority to say, to knowQuestions who has authority to say, to know
Experts vs. AmateursExperts vs. Amateurs
10. Individual Production &
User-Generated Content
Some definitions
Blog
Web log or diary; a web page organized
chronologically
Characteristics: chronological organization,
easy to set up, update
Describes format, not content
Exs: Armacost Library, TechDirt, Chronicle of
Higher Education
11. Individual Production &
User-Generated Content
Some definitions
RSS
Really Simple Syndication
Standardized feed format
Allows form and content to be separated
Based on XML
Allows for easy dissemination of frequently updated Web
documents
Users can subscribe to a page, receive notifications of
updates
RSS Reader exs: Bloglines, Google Reader
14. Harnessing the Power of the Crowd
Crowdsourcing, collective intelligence, the
wisdom of the crowd
Depends on collaboration – the social
aspect of the web
Questions authorship, ownership,
intellectual property rights
15. Harnessing the Power of the Crowd
The central principle behind the success of
the giants born in the Web 1.0 era who
have survived to lead the Web 2.0 era
appears to be this, that they have
embraced the power of the web to
harness collective intelligence.
-- Tim O’Reilly, “What Is Web 2.0,” 09/30/2005
16. Harnessing the Power of the Crowd
Wikipedia – prime example
Wiki
A web site/page that can be easily edited by
anyone who is allowed access
‘wiki’ – Hawaiian for ‘fast’
18. Harnessing the Power of the Crowd
Social bookmarking
Users choose terms to associate Web
pages/sites
Users organize information themselves
Activity: ‘tagging’
Result: ‘folksonomies’
Ex: Delicious
19. Harnessing the Power of the Crowd
Twitter
Social networking, micro-blogging service
Users send, read updates or ‘tweets’
Ex: Play Machinima Law Conference @
Stanford Law School CIS, April 24-25, 2009
http://cyberlaw.stanford.edu/

20. Data on an Epic Scale
Explosion of Information
Acceleration & Increase
Production
Dissemination
Distribution
Affects new and old media
Challenges established assumptions of order
21. Architecture of Participation
Design encourages participation,
contribution, lowers barriers
Based on ‘open’ principle
Opens up production to all users
Exposes data for reuse and recombination,
‘mash-up’
Questions ownership, intellectual property
rights
22. Architecture of Participation
Design implies continuous improvement
perpetual ‘beta’perpetual ‘beta’
Design ramps up ‘Web as Platform’Design ramps up ‘Web as Platform’
Questions perfectionism, established rules
of order, software release life cycle
23. Network Effects
More participation better tool, servicebetter tool, service
Wikipedia entry for network effectWikipedia entry for network effect
Critical mass must first be achieved
Ex: Wikipedia
24. Network Effects
Power Laws & The Long Tail
Power Law – mathematical concept,
frequency distribution
“80/20 Rule”
Power law distribution graphs tend to have
long tails
25. Network Effects
Power Laws & The Long Tail
The Long Tail – business strategy coined
by Chris Anderson, Oct 2004
remove physical barriers, demand for niche
products are actually high
Ex: Amazon.com
26. Network Effects
We are moving towards a culture and
economy in which the huge numbers of
people who do (or can) participate in the
niches of the Long Tail really matter.
-- Dr. Linda Main, LIBR 246-15,SJSU-SLIS Fall 2007
27. Openness
Open source
Open access
Open API (Application Programming Interface)
Exposes data
Free to use, access and remix
Services
Data
Questions ownership, intellectual property rights
32. So what?
It’s here, it’s now
What’s next?
Mobile services, SMS technology
What will happen to familiar formats, processes,
institutions?
33. So what?
It’s changing things
But what is it again?
Is this a publishing revolution?
To what extent?
Is it a revolution at all?
34. So what?
‘Teaching the Machine’
The semantic Web
Depends on us
‘The Machine is Us/ing Us’
Presents us with challenges, opportunities
Will we rise to meet them?
