General information

Name Enlarge Class Definition for Resolving Disjointness due to Subsomption.
Also known as
Author(s) Rim DJEDIDI
SubmittedBy RimDjedidi


Description

Motivation Problem:

Resolve disjointness –caused by a subsumption– by enlarging a class definition.

Competency Question: How to resolve disjointness –caused by a subsumption– by enlarging a definition of a class?

Aim The logical pattern models an alternative resolving disjointness inconsistency –caused by a subsumption– by enlarging the definition of a class.
Solution description The pattern resolves a disjointness inconsistency –caused by a subsumption–by enlarging the definition of the sub-class object of the disjointness inconsistency, based on the definition of disjoint classes involved in the inconsistency.

Process: 1) The pattern enlarges the definition of the sub-class object of the disjointness inconsistency by defining –in its description– a union of the definitions of the disjoint classes involved in the inconsistency to be resolved.

Elements the following elements are manipulated y the pattern:

ID of the class to enlarge (classID). ID(s) of the classes defining the enlargement. Operator : Union

Implementation
Reusable component
Component type


Example

Problem example Let’s consider the OWL ontology O defined by the following axioms:

{Animal ⊑Fauna-Flora, Plant ⊑Fauna-Flora, Carnivorous-Plant ⊑Plant, Plant ⊑ Not(Animal)}

If we apply a change to the ontology defining Carnivorous-Plant class as a sub-class of class Animal we cause a disjointness inconsistency as the class Carnivorous-Plant and the class Animal are disjointed. The proposed pattern propose a resolution alternative to this kind of inconsistency

Pattern solution example
Consequences Enlarge the definition of the class Carnivorous-Plant based on the definition of the classes Animal and Plant.

1) The pattern enlarges the definition of the sub-class object of the disjointness inconsistency Carnivorous-Plant by defining –in its description– a union of the definitions of the disjoint classes involved in the inconsistency: the classes Animal and Plant.
