13. So What is a Wiki By 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 about Quick and Easy – no need of extra software Collaborative Community Authoring Interlinked Content Version Control Notification 10

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

16. Wiki : the Web in the Small 12

17. The Small Web is just like the Whole Web Wikis are not perfect 13

18. Wikis Are Great … Enable new scale of human collaboration Everyone can read Everyone can write Everyone can edit Everyone is accountable for everything But some things are better left to machines… 14

19. Wiki Clock ? 15

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

25. Will Search Help? Not something you can do now… 17

26. Wikipedia’s answer: lists 18

30. Will you get your answers? 22

31. Wiki Answers? 23

32. Computers Are StupidComputers Need Our Help What computers can understand (powered by programs) is simple named entities, such as: ... 43285812 ... 2009-12-07 ... 400 Guoding Road, Shanghai, China ... Jesse Wang Still 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 Wiki 25

34. Semantic Wiki A Brief History 26

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 Wiki Views from all angles 33

57. Definition: Semantic Wikis Semantic 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 compatibility 34

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 ways More Structure  Knowledge Management Data in RDF  Ontology Reasoning Two Perspectives Wikis for Metadata Metadata for Wikis 35

59. Nova Spivack: MetaWeb Semantic Wikis 36

60. Semantic Wikis Benefits Annotation of existing structures with machine readable metadatalinks carry meaning, typing of links, typing of pages Context 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 information Improved interoperability between systemsexchange of content, integration of different systems, agents, etc 37

61. Semantic Wiki Illustrated 38

62. Basics of Semantic Wikis Still a wiki, with regular wiki features Category/Tags, Namespaces, Title, Versioning, ... Typed Content Page/Card, Date, Number, URL/Email, String, … Typed Links “capital_of”, “contains”, “born_in”… Querying Interface Support “[[Category:Member]] [[Age::<30]]” 39

63. Advanced Semantic Wiki Features Semantic forms or templates Auto-completion based on semantics Powerful visualizations based on semantics/structures/types Rules and reasoning support Advanced search and queries (faceted search, SPARQL, etc.) Import and Export of Semantic Data 40
