  3. 1. Introduction (1) • Wiki system + Semantic Web • SHAWN: Structure Helps a Wiki Navigate • WikSAR: Semantic Authoring and Retrieval within a Wiki • SemperWiki: A Semantic Personal Wiki • … • OntoWiki

  4. 1. Introduction (2) • OntoWiki Strategies • Intuitive display and editing • Semantic views • Versioning and Evolution • Semantic search • Community support • Online statistics • Semantic syndication

  5. 2. Visual Representation of Semantic Content (1) • List views: allow to view a selection of several instances in a combined view. • Individual views: combine all the properties attached to a particular instance.

  6. 2. Visual Representation of Semantic Content (2) • Different Views on Instance Data • Map View • Calendar View

  7. 3. Collaborative Authoring (1) • 1. Inline Editing • 2. Concept Identification and Reuse

  8. 3. Collaborative Authoring (2) • 3. Editing Widgets • Provided Widgets (prototypical OntoWiki) • Statements: allows editing of subject, predicate, and object • Nodes: edit literals or resources • Resources: select and search from/for existing resources • Literals: literal data in conjunction with a data type or a language identifier • Widgets for specific literal data types: e.g. dates, HTML fragments • File widget: allows uploading of files to the OntoWiki system

  9. 3. Collaborative Authoring (3) • 4. View Editing • Types of editable views: Metadata, Instances, Views

  10. 4. Enabling Social Collaboration • Social collaboration within OntoWiki • Change tracking: All changes applied to a knowledge base are tracked. • Commenting: All statements may be annotated, commented, and their usefulness can be rated. • Rating: Instances of the class can be rated according to special categories. • Popularity: All accesses are logged thus allowing to arrange views on the content based on popularity. • Activity/Provenance: This system keeps record of what was contributed by whom. (addition of instance data, commenting, …)

  11. 5. Semantic Search (1) • 1. Facet-Based Browsing Reference: http://3ba.se/resource/view/swrc%3AConference

  12. 5. Semantic Search (2) • 2. Semantically Enhanced Full-Text Search

  13. 6. Implementation and Status (1) • OntoWiki: an alternative user interface to the schema editor integrated in Powl(*Powl: platform for Semantic Web application development realized in a 3-tier architecture)

  14. 6. Implementation and Status (2) • OntoWiki is.. • Implemented in the Scripting language PHP • To be easily deployed on most Web hosting environment • Available as open-source software from SourceForge • Available at http://3ba.se • Extended and adopted within a variety of R&D projects

  15. Thank You!
