Method Detail

setEntityToDescribe

public void setEntityToDescribe(org.semanticweb.owlapi.model.OWLDataProperty entityToDescribe)

Overrides:

setEntityToDescribe in class PropertyAxiomLearner<org.semanticweb.owlapi.model.OWLDataProperty,T extends org.semanticweb.owlapi.model.OWLDataPropertyAxiom,org.semanticweb.owlapi.model.OWLDataPropertyAssertionAxiom>

Parameters:

entityToDescribe - the entity for which axioms will be computed

getAxiom

public abstract T getAxiom(org.semanticweb.owlapi.model.OWLDataProperty property,
                           org.semanticweb.owlapi.model.OWLDataProperty otherProperty)

Returns the hierarchy axiom based on the axiom type of the current learning algorithm between both properties. The relationship between both properties can be (1) subsumption, (2) equivalence or (3) disjointness.

Parameters:

property - the first property

otherProperty - the second property

Returns:

the hierarchy axiom

setBeta

public void setBeta(double beta)

Parameters:

beta - the beta to set

getBeta

public double getBeta()

setStrictMode

public void setStrictMode(boolean strictMode)

Parameters:

strictMode - the strictMode to set

isStrictMode

public boolean isStrictMode()

setBatchMode

public void setBatchMode(boolean batchMode)

If true, batch mode is used and only a single query will be used to compute the result. Otherwise, iteration over all properties in the ontology is done, i.e. at lots of queries - but simpler ones - will be executed.

Parameters:

batchMode -

isBatchMode

public boolean isBatchMode()
