The document discusses semantic mediawiki and applications. It provides an agenda that includes an introduction to semantic wikis, examples of semantic wikis, semantic mediawiki, useful extensions, and applications. It then goes on to provide background on wikis, their history and evolution, including the development of semantic wikis beginning in 2004/2005. It defines semantic wikis and discusses their benefits, features, and examples including popular semantic wikis like Semantic MediaWiki and KiWi.

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

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
