Ontologies are formal models relating to how we perceive the possible states of affairs in our domain of discourse.

Ontologies provide an effective means whereby human and electronic agents can communicate unambiguously about concepts by electronic means, which typically lack the facility for the user to ask for further clarification.

Interoperability between various ontologies will also become increasingly important in enabling members of disparate communities to reuse and understand digital information over time.
