  2. WebFilter Rules Profile Annotations AnnotationManager RuleManager ProfileManager HClass HTemp HClassManager HTempManager WebBrowser NKRL Filter prototypeGeneral architecture

  3. Phases of the process • 1st phase: creation of an ontology and a hierarchy of templates • 2nd phase: creation of NKRL annotations associated with web sites • 3rd phase: creation of the NKRL filtering rules • 4rd phase: establishment of a profile defining a level of filtering • 5th phase: browsing with a NKRL filter

  4. 1st phase: Creation of an ontology and a hierarchy of templates • NKRL expert user • HClassManager: • to add, remove, modify and browse concepts in a hierarchy • HClass repository • HTempManager: • to add, remove, modify and browse templates in a hierarchy • HTemp repository

  5. 1st phase - Creation of an ontology AnnotationManager - HClass Browser

  6. 1st phase - Creation of a hierarchy of templates AnnotationManager - HTemp Browser

  7. 2nd phase: Creation of annotations associated with web sites • NKRL expert user • AnnotationManager: • new version of an existing tool developed in Concerto project • to add, remove, modify and browse annotations representing sites • Annotations repository

  8. Concerto (NKRL objects) Bridge (NKRL objects) User Interface Compatibility required for the reuse of: • Filtering and Unification Module • Inference Engine Module developed in Concerto project 2nd phase - Creation of annotations AnnotationManager - General architecture

  9. 2nd phase - Creation of annotations AnnotationManager - Main window (Description view)

  10. 2nd phase - Creation of annotations AnnotationManager - Main window (Tree view)

  11. 2nd phase - Creation of annotations AnnotationManager - Creating a binding occurrence

  12. 2nd phase - Creation of annotations AnnotationManager - Creating a predicative occurrence

  13. 2nd phase - Creation of annotations AnnotationManager - Complex filler sequence of dialogs

  14. 3rd phase: creation of the NKRL filtering rules • NKRL expert user • RuleManager: • to add, remove, modify and browse filteringrules • some HClass concepts are associated with filtering rules • Rules repository

  15. 3rd phase: creation of the NKRL filtering rules WebBrowser - NKRL Filtering Rules

  16. 4rd phase: Establishment of a profile defining a level of filtering • Owner of the filter user (eg institution, parent,...) • ProfileManager • to add, remove, modify and browse ICRAcategories and the corresponding HClassconcepts • to select ICRA categories • that are associated with HClass concepts associated in turn with filtering rules • Profile repository • Rules repository

  17. ProfileManager WebFilter Profile Rules 4rd phase - Establishment of a profile

  18. 4rd phase - Establishment of a profile ProfileManager - Edit User Profile

  19. 4rd phase - Establishment of a profile ProfileManager - ICRA categories / HCLASS concepts

  20. 5th phase: Browsing with a NKRL filter • Final user (eg student,...) • WebBrowser • user interface • input: URL (inserted or clicked on the web page) • output: viewing of requested web pages when permitted by the NKRL filter • deals with the ProfileManager and WebFilter • functions to view all the process involved in the filtering of the web pages, calling: • AnnotationManager / RuleManager / HClassManager / HTempManager

  21. 5th phase - Browsing with NKRL filter WebBrowser - Main window
