An Extensible Semantic Wiki Architecture An Extensible Semantic Wiki Architecture Presentation Transcript

  • An Extensible Semantic Wiki Architecture The Semantic Wiki Extension Space
    Jochen Reutelshöfer, Fabian Haupt,
    Florian Lemmerichand Joachim Baumeister,
    University of Würzburg
    Germany
  • Semantic Wiki
    Whatis a Semantic Wiki?
    „Semanticallyenriched“ content
    Allowingforsome additional functionalitybeyondreadingandbrowsing
    Examples: Semantic MediaWiki, KIWI, SWIM, AceWiki, SweetWiki,…
    Problem:
    Wiki means: fast and simple
    enrichingthecontentmeans: …
    Danger
    not so fast and not so simple (anymore) ?
  • Why Extending(Semantic) Wikis?
    Customization: tailored to specific applications
    Lowers barriers of usage
    Higher efficiency in formalization
    Extension: more complex knowledge management
    Problem-solving knowledge, flowchart-editing
    Advanced editing support
    Exploitation of further formalization techniques
    NLP, Text Mining
    Customized to a startup corpus

  • Application: Hermes Wiki
    Developers: Chair of ancient greek history, 4-6 people (University of Würzburg)
    Task: Connecting explaining text, formalized time events and historical sources
    Purpose: Exam preparation for students
    Content: > 500 pages, ~ 600 time events, >100 Google-maps, > 350 concepts (historical characters, places, peoples, rites…)
