Method Detail

getExplanations

public Set<Explanation<org.semanticweb.owlapi.model.OWLAxiom>> getExplanations(org.semanticweb.owlapi.model.OWLAxiom entailment)
                                                                        throws ExplanationException

Gets explanations for an entailment. All explanations for the entailment will be returned.

Specified by:

getExplanations in interface ExplanationGenerator<org.semanticweb.owlapi.model.OWLAxiom>

Parameters:

entailment - The entailment for which explanations will be generated.

Returns:

A set containing all of the explanations. The set will be empty if the entailment does not hold.

Throws:

ExplanationException - if there was a problem generating the explanation.

getExplanations

public Set<Explanation<org.semanticweb.owlapi.model.OWLAxiom>> getExplanations(org.semanticweb.owlapi.model.OWLAxiom entailment,
                                                                               int limit)

Gets explanations for an entailment, with limit on the number of explanations returned.

Specified by:

getExplanations in interface ExplanationGenerator<org.semanticweb.owlapi.model.OWLAxiom>

Parameters:

entailment - The entailment for which explanations will be generated.

limit - The maximum number of explanations to generate. This should be a positive integer.

Returns:

A set containing explanations. The maximum cardinality of the set is specified by the limit parameter. The set may be empty if the entailment does not hold, or if a limit of zero or less is supplied.

Throws:

ExplanationException - if there was a problem generating the explanation.
