           What makes a Wiki
• Collaborative Writing
• Easy editing and changing (wiki=quickly)
• Monitoring changes
    – History saved
    – Revert option
• Searching utility

• Problems: Spam, Vandalism               1994-1995

9                     www.sharon-it.com
           Spam Prevention
• Restricting the use of certain words or
  phrases, using word lists or regular
  expressions.
• Blocking access based on excessive
  activity.




10                www.sharon-it.com
                          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.

      Blogs




15   www.sharon-it.com
               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.


16                     www.sharon-it.com
     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.


17                     www.sharon-it.com
           Blog Search Engines
•    Technorati.com www.technorati.com/
•    BlogLines www.bloglines.com/
•    BlogDigger blogdigger.com/
•    Blogdex.net blogdex.net/search.asp

18                 www.sharon-it.com
                    Technorati
• The best one around

     – All words, exact phrase, at least one, not
     – Search all blogs, by topic, by URL

19                     www.sharon-it.com
     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)

                      Blog vs. Wiki
               Blog                                    Wiki

•    Ordered by dates                   • Ordered by topics
•    Older posts not changed            • Constant update
•    Have comments/
     talkbacks by viewers               • Have updates/additions by
                                          viewers and comments

                                                               * usually
21                            www.sharon-it.com
     Ajax
 Asynchronous
 JavaScript
 and XML



22              www.sharon-it.com
       Example Ajax Applications
•    Google Maps/Local (Yahoo, A9)
•    Housing Maps
•    Google Suggest
•    Windows live
•    Yahoo! Instant Search
•    GMail
•    Wall Street Journal
•    And many more..
23                  www.sharon-it.com
               Google Suggest
• As you type – you get query suggestions
  and number of results per query.
• labs.google.com/suggest




24               www.sharon-it.com
         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.

25                    www.sharon-it.com
                  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




27           www.sharon-it.com
         Web 2.0 – Future?
• Web 2.0 and the enterprise
• Opportunities in “Web n.0”
• What is “Web 3.0”?




28               www.sharon-it.com
                         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
30                            www.sharon-it.com
                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

32                        www.sharon-it.com
     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.
• http://blog.outer-court.com/forum/17079.html
33                   www.sharon-it.com
     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.”
