Ontologies g

Semantic Web

  • Built on existing standards

Semantic Web Project

  • Built on existing standards
  • Specify information semantics
  • Machine interpretable
  • Support reasoning
  • Extendible

Once a certain domain has been specified using an ontology, ft t b d th t l i t bl d software agents based on the same ontology are interoperable and so may communicate and cooperate

Generic Approach to pp Interoperability

  • Scenario analysis and application requirements

Scenario analysis and application requirements

  • Ontology as a formal representation of the detected

Ontology as a formal representation of the detected concepts and properties

  • HW/SW architecture
  • Implementation and testing

Maintenance Domain

  • Sensor networks provide data about environment
  • Rules and normatives specify limits over which fault are

detected

  • Faults are signaled and communicated to maintenance

companies and operators p p

  • Maintenance interventions are scheduled and performed
  • Office tenants are informed of faults and intervetion which

happens in their office to have a less intrusive intervention

  • Maintenance operators are guided to fault location and signal

start and end of operation p

Operator GUI p

  • Acceptation by only one of the

pool of appropriately skilled

  • perators
  • Synchronization of multiple

acceptations

  • Fault info to help the operator

The fault in your office has been repaired

  • Buttons to interact with the SIB
  • Notification of all processes

interested in the modified fault instances => Tenant GUI
