myPlanet an ontology-driven Web-based
personalised news service

• web based newsletter by creating a profile based
  on an ontology.

• to improve and ease ontology usability for web
  users by means of ontology-driven front-ends to
  personalized services.

• to provide lightweight means for ontology
  maintenance triggered by users input by

  specific templates.

Ontological interest-profiling
myPlanet an ontology-driven Web-based
personalised news service

• read only the e-Stories of their interest
• reason about the categories selected by applying
  ontology-driven deductive heuristics
• find implicitly related e-Stories

• Research areas that are investigated in KMi
• Research themes that are investigated in KMi
• Organizations that KMi collborates with
• Projects in KMi
• Technologies used in KMi
• Application domains that are investigated in KMi
• People members of the KMi lab

Ontological interest-profiling

• OCML supports the construction of knowledge
  models by means of several types of constructs.
• It allows the specification and
  operationalization of functions, relations,
  classes and rules.

• abstraction of the category that is associated
  with
• evidence that e-Story which contains it is
  relevant to that category

Populating the ontology
myPlanet an ontology-driven Web-based
personalised news service

• domain specific templates
• based on typology of events
• ex) visiting-a-place-or-people,
  academic-conference, event-involving-project
  
• key is the trigger word
• ex) _, X, _, visited, Y, from, Z, _
