  9. 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 www.sharon-it.com

  10. 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.com

  11. 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 www.sharon-it.com

  12. ויקיפדיה בעברית www.sharon-it.com http://he.wikipedia.org

  13. ויקיפדיה בעברית • משתמשת ב-MediaWikiwww.mediawiki.org • כמו כן רבות אחרות • מופעלת על ידי מתנדבים ותורמים • כ-37,000 ערכים • כ-3,000 עדכונים ביום • כ-10 ערכים נעולים www.sharon-it.com

  14. 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.com

  15. Blogs www.sharon-it.com

  16. 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.com

  17. 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.com

  18. 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.com

  19. 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.com

  20. 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.com

  21. 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 Blog vs. Wiki • http://betsysblog.blogspot.com/2005_03_01_betsysblog_archive.html • http://www.samizdata.net/blog/glossary_archives/006470.html * usually www.sharon-it.com

  22. Ajax Asynchronous JavaScript and XML www.sharon-it.com

  23. 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.com

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

  25. 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.com

  26. 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. www.sharon-it.com

  27. Web 2.0 and the Future www.sharon-it.com

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

  29. 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 www.sharon-it.com

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

  31. 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=68http://blogs.zdnet.com/SAAS/?p=83 www.sharon-it.com

  32. Web 3.0 is (real) 3D • Real 3D • Think Web 4.0 http://blog.outer-court.com/forum/17079.html • Philip Torrone jokingly mentioned to me the other day (inside Second Life) that 3D was Web 3.0 • Web x.0, Joi Itohttp://joi.ito.com/archives/2005/10/10/web_x0.html www.sharon-it.com

  33. 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 www.sharon-it.com

  34. 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 • Also in: http://radar.oreilly.com/archives/2006/04/second_order_consequences_of_w.html www.sharon-it.com
