interrupted in class ReasoningUtils

Returns:

getCoverageCLP

public ReasoningUtils.Coverage[] getCoverageCLP(org.semanticweb.owlapi.model.OWLClassExpression description,
                                                Collection<org.semanticweb.owlapi.model.OWLIndividual> classInstances,

get coverage result for class learning problem. currently this is specialised for SPARQL reasoner and uses generic getCoverage otherwise

Parameters:

description - the description to test

classInstances - instances of the target class

superClassInstances - instaces of the superclass

Returns:

array of coverage data

getAccuracyOrTooWeak3

description - description to test

classInstances - class instances. will be converted to set

superClassInstances - superclass instances. will be converted to set

negatedClassInstances - negated class instances. will be converted to set

noise - problem noise

Returns:

accuracy or -1
