Method Detail

refine

public abstract Set<org.semanticweb.owlapi.model.OWLClassExpression> refine(org.semanticweb.owlapi.model.OWLClassExpression description)

Description copied from interface: RefinementOperator

Standard refinement operation.

Specified by:

refine in interface RefinementOperator

Parameters:

description - The description, which will be refined.

Returns:

A set of refinements.

refine

public Set<org.semanticweb.owlapi.model.OWLClassExpression> refine(org.semanticweb.owlapi.model.OWLClassExpression description,
                                                                   int maxLength)

Description copied from interface: LengthLimitedRefinementOperator

Optional refinement operation, where the learning algorithm can specify an additional bound on the length of descriptions.

Specified by:

refine in interface LengthLimitedRefinementOperator

Parameters:

description - The description, which will be refined.

maxLength - The maximum length of returned description, where length is defined by OWLClassExpressionUtils.getLength(OWLClassExpression) }.

Returns:

A set of refinements obeying the above restrictions.

refine

public Set<org.semanticweb.owlapi.model.OWLClassExpression> refine(org.semanticweb.owlapi.model.OWLClassExpression description,
                                                                   int maxLength,

Description copied from interface: LengthLimitedRefinementOperator

Optional refinement operation, where the learning algorithm can specify an additional bound on the length of descriptions and a list of known refinements, which do not need to be returned.

Specified by:

refine in interface LengthLimitedRefinementOperator

Parameters:

description - The description, which will be refined.

maxLength - The maximum length of returned description, where length is defined by OWLClassExpressionUtils.getLength(OWLClassExpression).

knownRefinements - A collection of known refinements, which do not need to be returned.

Returns:

A set of refinements obeying the above restrictions.
