13. So What is a WikiBy Wikipedia:A wiki (pronounced /ˈwɪki/ WIK-ee) is a website that allows the easy[1] creation and editing of any number of interlinked web pages via a web browser using a simplified markup language or a WYSIWYG text editor.[2][3] Wikis are typically powered by wiki software and are often used to createcollaborative websites, to power community websites, for personal note taking, in corporate intranets, and in knowledge management systems.9

14. What Wiki Really Is aboutQuick and Easy – no need of extra softwareCollaborative Community AuthoringInterlinked ContentVersion ControlNotification 10

15. Wiki as Productivity PlatformWiki is not only a wiki engine, web site, hosting service…It is a social, collaborative productivity toolIt is a platform where people can build web applicationsIt marries the web of computers with the web of peopleIt is a great indicator of human Civilization!11

16. Wiki : the Web in the Small12

17. The Small Web is just like the Whole WebWikis are not perfect13

18. Wikis Are Great …Enable new scale of human collaborationEveryone can readEveryone can writeEveryone can editEveryone is accountable for everythingBut some things are better left to machines…14

19. Wiki Clock ?15

20. Limits of TheWiki: WikipediaWikipedia has articles about…

21. … all cities

22. … their populations

23. … their mayors

24. … the skyscrapersSo can I ask for a list of the world’s 10 largest cities with a female mayor?Or Skyscrapers in Shanghai with 50+ floors and built after 2000?16

32. Computers Are StupidComputers Need Our HelpWhat computers can understand (powered by programs) is simple named entities, such as:... 43285812... 2009-12-07... 400 Guoding Road, Shanghai, China... Jesse WangStill not always correct with all the possible variations of formats...24

33. How to get the Answers in the wikis?The female majors of top 10 cities, sorted by population, starting year, age…All skyscrapers in China (Japan, Thailand,…) of 50 (40/60/70) floors or more, and built in year 2000 (2001/2002) and after, sorted by built year, floors…, grouped by cities, regions…Median (average) base annual salary of CEOs of Fortune 100 companies in America (Europe, Asian,…)(And so on…)Semantic Wiki25

34. Semantic WikiA Brief History26

35. 1995: The First WikiWiki – Hawaiian word for “quick and easy”

36. First developed by Ward Cunningham as an add-on to the Portland Pattern Repository on 1995.03.25

37. http://c2.com/cgi/wiki?WikiDesignPrinciples our interpretation

38. Incremental - Pages can cite other pages, including pages that have not been written yet.  network of pages

39. Organic - The structure and text content of the site is open to editing and evolution.  different from classical content management systems

40. Universal - The mechanisms of editing and organizing are the same as those of writing so that any writer is automatically an editor and organizer.  integrated creation and organization of content

41. Unified - Page names will be drawn from a flat space so that no additional context is required to interpret them.  humans can remember names

42. Precise - Pages will be titled with sufficient precision to avoid most name clashes, typically by forming noun phrases.  names are quasi-unique

43. Tolerant - Interpretable (even if undesirable) behavior is preferred to error messages.  usability: novice users have less fear to start using it

44. Observable - Activity within the site can be watched and reviewed by any other visitor to the site.  exchange of meta-information

45. Convergent - Duplication can be discouraged or removed by finding and citing similar or related content.  27

56. Semantic WikiViews from all angles33

57. Definition: Semantic WikisSemantic Wiki is a wiki that has an underlying model of the knowledge described in its pages.The knowledge model found in a semantic wiki is typically available in a formal language, so that machines can process it into an entity-relationship or relational database.Semantic Web compatibility34

58. To View It In Different Ways To allow users to make their internal knowledge more explicit and more formal, so that the information in a wiki can be searched and presented in better waysMore Structure  Knowledge ManagementData in RDF  Ontology ReasoningTwo PerspectivesWikis for MetadataMetadata for Wikis35

59. Nova Spivack: MetaWebSemantic Wikis36

60. Semantic Wikis BenefitsAnnotation of existing structures with machine readable metadatalinks carry meaning, typing of links, typing of pagesContext dependent adaptation and presentationdifferent domains have different ways of presenting content, personal preferences, etc.Improved, „intelligent“, search and navigationqueries to the structure, visualisation of structure, derived informationImproved interoperability between systemsexchange of content, integration of different systems, agents, etc37
