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


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


AnnotationManager - HClass Browser1st phase - Creation of an ontology


AnnotationManager - HTemp Browser1st phase - Creation of a hierarchy of templates


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


Compatibility required for the reuse of:

– Filtering and Unification Module– Inference Engine Module

developed in Concerto project

Concerto (NKRL objects)

Bridge (NKRL objects)

AnnotationManager - Complex filler sequence of dialogs2nd phase - Creation of annotations


3rd phase: creation of the NKRL filtering rules

– NKRL expert user– RuleManager:

• to add, remove, modify and browse filtering rules

• some HClass concepts are associated with filtering rules

• Rules repository


WebBrowser - NKRL Filtering Rules3rd phase: creation of the NKRL filtering rules


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 ICRA categories and the corresponding HClass concepts

• to select ICRA categories – that are associated with HClass concepts

associated in turn with filtering rules

• Profile repository• Rules repository

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
