Ontology Sharing

Ontology Sharing

Three Alternatives

• Create a committee to define everybody’s terms
  • Takes many years, until people are worn out
  • Ignored when changes make deviation necessary
  • Get all terms and put them into large model

  [ Cyc, UMLS, Federated Schemas, . . . ]

  • Can be rapid
  • Ignores conflicts
  • Hard to maintain (requires committee)
  • Keep all Terms distinct, except where sharing
    • Requires initial effort
    • Empowers participants
