This work describes the application of semantic wikis in distant learning for Semantic Web courses. The resulting system focuses its application of existing and new wiki technology in making a wiki-based interface that demonstrates Semantic Web features. A new layer of wiki technology, called “OWL Wiki Forms” is introduced for this Semantic Web functionality in the wiki interface. This new functionality includes a form-based interface for editing Semantic Web ontologies. The wiki then includes appropriate data from these ontologies to extend existing wiki RDF export. It also includes ontology-driven creation of data entry and browsing interfaces for the wiki itself. As a wiki, the system provides the student an educational tool that students can use anywhere while still sharing access with the instructor and, optionally, other students.

Applying and Extending Semantic Wikis for Semantic Web Courses Applying and Extending Semantic Wikis for Semantic Web Courses Presentation Transcript

  • Applying and Extending Semantic Wikis for
    Semantic Web CoursesLinkedLearning 2011, 29 May 2011
    Lloyd Rutledge, Open Universiteit
  • Independent students
    Education as distance collaboration
    Flexible schedules
  • Many conforming Semantic Web functions
    Well-known oft-used tool
    Specializes in editing ontologies
    • Online, sharable, universal
    • Specializes in data retrieval
    • XSLT can tailor data report presentation
    • Online, sharable, universal
    • Specializes in distance collaboration
    • Well-supported, has extension framework
  • Wikipedia infobox: open data editing
    • MediaWiki extension
    • Well-supported, active development
    • Semantic Web: -ish, -partial
    • Annotation syntax
    • Data queries and formatted reports
    • RDF export
    • Semantic MediaWiki extension
    • Infobox-like templates for data browsing
    • Forms for data entry
    • Primitives for building ontology-based interface
  • Semantic MediaWiki for Distance Learning
    Student and teacher share environment
    From anywhere, anytime
    Student can build
    Teach can track and query
    Student can build full data system
    Ontologies, data, tailored interface
    Does everything, but nothing well
    Little internal Semantic Web support
  • Forms of education use of Semantic MediaWiki
    Student projects
    Done for Bachelors and Masters
    Semantic wiki is foundation for system building
    Courseware
    Course information
    Student assignments and projects
  • Semantic MediaWiki for the Semantic Web
    Really?
    Started as a research baby step toward
    Has become short-term industry driven
    Many near equivalents and “not quites”
    Components
    Own data annotation syntax
    Own query language
    Although several extensions offer SPARQL
    Many query result presentations formats
    RDF export with Linked Data links
    Little internal Semantic Web support
  • OWL Wiki Forms
    Editing Semantic Web ontologies
    Forms and infoboxes for ontologies
    Classes and properties in RDF, RDFS and OWL
    Also in RDF export
    Semantic MediaWiki annotations in infobox code
    rdf:datatype -> [[Has type::]]
    owl:inverseOf -> SMW’s invert-property template
    Inferencing in infobox displays
    rdfs:domain -> property in template and form
    owl:symmetricProperty -> in infobox both ends of triple
    Inferencing in Forms input
    rdfs:range -> Semantic Forms autocompletion parameters
  • Conclusion
    MediaWiki for teacher access
    The more on the wiki the better
    The Semantic Web in the wiki
    Remains an “extra” tool for students
    Future work
    More SPARQL usage: internal & external
    Fresnel integration
    Additional semantic browsing features
    Continued integration with new extensions
