General description

Name: Transition
Submitted by: AldoGangemi
Also Known As:
Intent: To represent basic knowledge about transitions (events, states, processes, objects).
Domains:
Competency Questions:
  • What states of some object are changed by what event during a transition?
  • What is the process that is invariant through the transition?
  • What transitions are occurring on what object at what time?
Solution description:
Reusable OWL Building Block: http://ontologydesignpatterns.org/cp/owl/transition.owl (1058)
Consequences: We are able to represent part of the semantics involved in transitions (e.g. what is implied by Petri Nets): initial and final states, causal events, underlying processes, affected objects, and sequences of time intervals for situations and events.

However, it is not possible to define axioms for automatically infer initial and final states from time sequences, because coreference is not allowed in OWL (not even in OWL2).

Scenarios: The addition of Bud Powell on piano made the tune jump from a static, aerial comping into a hard driving swing improvisation

Elements

The Transition Content OP locally defines the following ontology elements:

ObjectProperty hasEventAtTime (owl:ObjectProperty) The time of the event causing the transition.
hasEventAtTime page
ObjectProperty hasFinalStateAtTime (owl:ObjectProperty) The time of the final state of the transition.
hasFinalStateAtTime page
ObjectProperty hasInitialStateAtTime (owl:ObjectProperty) The time of the initial state in the transition.
hasInitialStateAtTime page
ObjectProperty includesFinalSituation (owl:ObjectProperty) A relation between a transition situation and the situation resulting from the transition.
includesFinalSituation page
ObjectProperty includesInitialSituation (owl:ObjectProperty) A relation between a transition situation and the situation existing before the transition event.
includesInitialSituation page
ObjectProperty includesProcess (owl:ObjectProperty) A relation between a transition situation and the underlying process that is invariant for the object(s) included in the transition.
includesProcess page
ObjectProperty isFinalSituationIncludedIn (owl:ObjectProperty) A relation between a transition situation and the situation resulting from the transition.
isFinalSituationIncludedIn page
ObjectProperty isInitialSituationIncludedIn (owl:ObjectProperty) A relation between a transition situation and the situation existing before the transition event.
isInitialSituationIncludedIn page
ObjectProperty isProcessIncludedIn (owl:ObjectProperty) A relation between a transition situation and the underlying process that is invariant for the object(s) included in the transition.
isProcessIncludedIn page
ObjectProperty isTimeOf (owl:ObjectProperty)
isTimeOf page
ObjectProperty occursAt (owl:ObjectProperty)
occursAt page
Class Process (owl:Class) The invariance under some different transitions (including the one represented here), in which at least one Object is situated.
Process page
Class Transition (owl:Class) In this pattern, it is the entity that is invariant across the Process underlying the transition, but is also changed from an initial to a final state by an Event.


A transition is a Situation that creates a context for three TimeInterval(s), two additional different Situation(s), one Event, one Process, and at least one Object: the Event is observed as the cause for the transition, one Situation is the state before the transition, the second Situation is the state after the transition, the Process is the invariance under some different transitions (including the one represented here), in which at least one Object is situated. Finally, the time intervals position the situations and the transitional event in time.

This class of situations partly encodes the ontology underlying typical engineering algebras for processes, e.g. Petri Nets.

A full representation of the transition ontology is outside the expressivity of OWL, because we would need qualified cardinality restrictions, coreference, property equivalence, and property composition.
