What makes a Wiki• Collaborative Writing• Easy editing and changing
(wiki=quickly)• Monitoring changes
– History saved– Revert option
• Searching utility
• Problems: Spam, Vandalism1994-1995
www.sharon-it.com10
Spam Prevention• Restricting the use of certain words
or phrases, using word lists or regular expressions.
• Blocking access based on excessive activity.
www.sharon-it.com11
Vandalism
• Studies from IBM claim that most vandalism to Wikipedia is removed in 5 minutes or less.
• In some cases it takes longer, as in the John Seigenthaler Sr. Wikipedia biography controversy.
• In some cases, user accounts or IP addresses are banned from editing certain wikis, and certain pages may be 'locked', to prevent further vandalism. http://researchweb.watson.ibm.com/history/results.htm

Enterprise Wiki?• Motorola is using TWiki• Intel
– Used for technical encyclopedia– Implemented using MediaWiki, integrated with
Google Search– Launched March 2006 (preceded by pilot)– Supporting user training program– Over 3,000 article– 10% active users (edited more than 2 pages)– Problems: information security/need for a
better permission mechanism
www.sharon-it.com15
Blogs
www.sharon-it.com16
What is a Blog• A blog (shorthand for weblog) is a
web-based publication consisting primarily of periodic articles, most often in reverse chronological order:– Publication– Posts by dates– Includes links, multimedia, etc.
www.sharon-it.com17
Blogs and Search Engines• Regular Search Engines average
indexing delay is as high as 6-8 weeks.• Regular Search Engines promote blogs in
results, but not efficiently.• Therefore, use Blog search engines to
find:– Breaking news– Most recent information
• Blog search is typically sorted by date but with popularity sort option.
www.sharon-it.com18
Blog Search Engines• Technorati.com www.technorati.com/ • BlogLines www.bloglines.com/ • BlogDigger blogdigger.com/ • Blogdex.net blogdex.net/search.asp• IceRocket.com www.icerocket.com • Google BlogSearch
blogsearch.google.com • Clusty blogs.clusty.com• Sphere www.sphere.com
www.sharon-it.com19
Technorati• The best one around• Many options:
– All words, exact phrase, at least one, not– Search all blogs, by topic, by URL– Search by Tags– Blog fine– Popular
www.sharon-it.com20
BlogSearch Recommendations
• Technorati is the best• For Hebrew search
– Google Blogsearch– Clusty– Language Filter in Technorati when
relevant
• Use Clusty when you need more results (but typically less accurate)
• Use BlogDigger for location (US)
www.sharon-it.com21
Blog vs. WikiBlog
• Personal expression• Ordered by dates• Older posts not
changed• Have comments/
talkbacks by viewers
Wiki• Collaborative
contribution• Ordered by topics• Constant update
• Have updates/additions by viewers and comments•http://betsysblog.blogspot.com/

Ajax
Asynchronous JavaScript and XML
www.sharon-it.com23
Example Ajax Applications• Google Maps/Local (Yahoo, A9)• Housing Maps• Google Suggest• Windows live• Yahoo! Instant Search • GMail• Wall Street Journal• And many more..
www.sharon-it.com24
Google Suggest• As you type – you get query
suggestions and number of results per query.
• labs.google.com/suggest
www.sharon-it.com25
AlltheWeb LiveSearch• Yahoo’s AlltheWeb now has a new
Livesearch feature. • It takes the Google Suggest approach
a step further. • You will instantly see the results to
the right side.
• http://livesearch.alltheweb.com/?ek=1
www.sharon-it.com26
Ajax Pros/Cons• Pros
– Interactivity!• Cons
– It might easily break the expected behavior of the browser's back button
– Difficult for a user to bookmark a particular state of the application
– Users might experience delay in the interface of the web application
– It requires users to have JavaScript (or ActiveX) enabled in their browsers
– A challenge for developers interested in adhering to WAI accessibility guidelines.

Web 2.0 and the Future
www.sharon-it.com28
Web 2.0 – Future?• Web 2.0 and the enterprise• Opportunities in “Web n.0”• What is “Web 3.0”?
www.sharon-it.com29
Gartner Says…• Web 2.0 Offers Many Opportunities for Growth, But
Few Enterprises Will Immediately Adopt All Aspects Necessary for Significant Business Impact.
• By 2008, the majority of Global 1000 companies will quickly adopt several technology-related aspects of Web 2.0, but will be slow to adopt the aspects of Web 2.0 that have a social dimension, and the result will be a slow impact on business, according to Gartner, Inc.
• "While it is straightforward to add specific technologies, such as Ajax or RSS to products, platforms and applications, it is more difficult to add a social dimension"

Web n.0?
http://blog.outer-court.com/archive/2006-01-17-n79.html
www.sharon-it.com31
Web 3.0 is: Enterprise Web 2.0
(i.e Business Applications)• Web 3.0 is going to deliver a new generation of
business applications • brief topology of Web 3.0. It's divided into three (and a half)
distinct layers:– API services form the foundation – Aggregation services form the middle layer – Application services form the top layer – Serviced clients are the and-a-half

Web 3.0 is (real) 3D
1. Real 3D– Think Web 4.0
http://blog.outer-court.com/forum/17079.html
2. Philip Torrone jokingly mentioned to me the other day (inside Second Life) that 3D was Web 3.0
– Web x.0, Joi Ito http://joi.ito.com/archives/2005/10/10/web_x0.html
www.sharon-it.com33
Web 3.0 is the Semantic Web
• Web 1.0 was the Hypertext/CGI Web. (the basics) Web 2.0 is the Community Web (for people: apps/sites connecting them). Web 3.0 is the Semantic Web (for machines). Web 2.0 and Web 3.0 are a fork we are moving into now
• Web 4.0 is when these technologies come together to form what I call the "Learning Web". This is moving more into the area of Artificial Intelligence.

Web 3.0 is “the sensor-web”• Web 3.0 is “the sensor-web, in which
the architecture of participation will be an automatic byproduct of the devices we carry around with us.”http://www.stubbleblog.com
