• A knowledge management scenario
• Imagine an inexperienced employee in a public
  organisation

but who should I be consulting? Has anyone
written anything similar that I could reuse? Or
maybe theres even a template?
I know Im supposed to be producing a report for
the assessment
How long will it take to get a response? Is there
anyone whos done this before?

Ontologies in PELLUCID

• Generic Ontology
• Domain Specific Ontologies

System Architecture

• Hybrid Approach
• Knowledge centralized in Organizational Memory
• Distributed in Agents

• Query creation GUI
• GUI generated from Ontology
• Extracting Knowledge
• Query on the picture can be read as follows
  Return All EventContacts where BusinessEntity
  (contact contacted) is Police Department and I am
  interested in the employee, which made the
  contacts. Note that ontological elements adopt
  tree structure from inheritance of ontology
  elements.
