Constructor Detail

EvaluatedDescriptionClass

public EvaluatedDescriptionClass(org.semanticweb.owlapi.model.OWLClassExpression description,
                                 ClassScore score)

Constructs an evaluated class expression for learning classes in ontologies.

Parameters:

description - Description.

score - Score of description.

Method Detail

getAddition

public double getAddition()

Returns:

The addition factor.

See Also:

ClassScore.getAddition()

getAdditionalInstances

public Set<org.semanticweb.owlapi.model.OWLIndividual> getAdditionalInstances()

Returns:

The instances of the class description, which are not instances of the class to learn.

See Also:

ClassScore.getAdditionalInstances()

getCoverage

public double getCoverage()

Returns:

The coverage percentage.

See Also:

ClassScore.getCoverage()

getCoveredInstances

public Set<org.semanticweb.owlapi.model.OWLIndividual> getCoveredInstances()

Returns:

The instances covered by the class description.

See Also:

ClassScore.getCoveredInstances()

getNotCoveredInstances

public Set<org.semanticweb.owlapi.model.OWLIndividual> getNotCoveredInstances()

Returns:

The instances of the class not covered by the class description.

See Also:

ClassScore.getCoveredInstances()

isConsistent

public boolean isConsistent()

Returns:

True if adding the axiom to the knowledge base leads to an inconsistent knowledge base. False otherwise.

followsFromKB

public boolean followsFromKB()

Returns:

True if adding the axiom to the knowledge base does not logically change the knowledge base (i.e. the axiom already follows from it). False otherwise.

setConsistent

public void setConsistent(boolean isConsistent)

setFollowsFromKB

public void setFollowsFromKB(boolean followsFromKB)

asJSON

public String asJSON()

This convenience method can be used to store and exchange evaluated descriptions by transforming them to a JSON string.

Overrides:

asJSON in class EvaluatedDescription<ClassScore>

Returns:

A JSON representation of an evaluated description.
