In some cases it takes longer, as in the John Seigenthaler Sr. Wikipedia biography controversy.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

20 www.sharon-it.com20 ויקיפדיה בעברית משתמשת ב-MediaWiki www.mediawiki.orgwww.mediawiki.org –כמו כן רבות אחרות מופעלת על ידי מתנדבים ותורמים כ-37,000 ערכים כ-3,000 עדכונים ביום כ-10 ערכים נעולים

21 www.sharon-it.com21 MediaWiki.org

22 www.sharon-it.com22 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

23 www.sharon-it.com23 Uncyclopedia

24 www.sharon-it.com24 Blogs

25 www.sharon-it.com25 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.

26 www.sharon-it.com26 A Blog

27 www.sharon-it.com27 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.

28 www.sharon-it.com28 Blog Search Engines Technorati.com www.technorati.com/www.technorati.com/ BlogLines www.bloglines.com/www.bloglines.com/ BlogDigger blogdigger.com/blogdigger.com/ Blogdex.net blogdex.net/search.aspblogdex.net/search.asp IceRocket.com www.icerocket.comwww.icerocket.com Google BlogSearch blogsearch.google.comblogsearch.google.com Clusty blogs.clusty.comblogs.clusty.com Sphere www.sphere.comwww.sphere.com

29 www.sharon-it.com29 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

30 www.sharon-it.com30

31 www.sharon-it.com31

32 www.sharon-it.com32 Technorati by tags

33 www.sharon-it.com33 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)

34 www.sharon-it.com34 Blog vs. Wiki Blog 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/2005_03_01_betsysblog_ archive.htmlhttp://betsysblog.blogspot.com/2005_03_01_betsysblog_ archive.html http://www.samizdata.net/blog/glossary_archives/006470.htmlhttp://www.samizdata.net/blog/glossary_archives/006470.html * usually

35 www.sharon-it.com35 Ajax Asynchronous JavaScript and XML

36 www.sharon-it.com36 Example Ajax Applications Google Maps/Local (Yahoo, A9) Housing Maps Google Suggest Windows live Yahoo! Instant Search GMail Wall Street Journal And many more..

37 www.sharon-it.com37

38 www.sharon-it.com38 Google Suggest As you type – you get query suggestions and number of results per query. labs.google.com/suggest

39 www.sharon-it.com39 AlltheWeb LiveSearch Yahoo’s AlltheWeb now has a new Livesearch feature. Livesearch It takes the Google Suggest approach a step further.Google Suggest You will instantly see the results to the right side. http://livesearch.alltheweb.com/?ek=1

44 www.sharon-it.com44 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.

45 www.sharon-it.com45 Web 2.0 and the Future

46 www.sharon-it.com46 Web 2.0 – Future? Web 2.0 and the enterprise Opportunities in “Web n.0” What is “Web 3.0”?

47 www.sharon-it.com47 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" Tuesday May 16, 2006 http://biz.yahoo.com/bw/060516/20060516005941.html?.v=1

48 www.sharon-it.com48 Web n.0? http://blog.outer-court.com/archive/2006-01-17-n79.html

49 www.sharon-it.com49 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 Phil Wainewright http://blogs.zdnet.com/SAAS/?p=68 http://blogs.zdnet.com/SAAS/?p=83http://blogs.zdnet.com/SAAS/?p=68 http://blogs.zdnet.com/SAAS/?p=83

50 www.sharon-it.com50 Web 3.0 is (real) 3D 1.Real 3D –Think Web 4.0 http://blog.outer- court.com/forum/17079.htmlhttp://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 http://joi.ito.com/archives/2005/10/10/web_x0.html

51 www.sharon-it.com51 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

52 www.sharon-it.com52 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 http://www.stubbleblog.com Also in: http://radar.oreilly.com/archives/2006/04/ second_order_consequences_of_w.html http://radar.oreilly.com/archives/2006/04/ second_order_consequences_of_w.html
