Method Detail

getCurrentlyBestDescriptions

List<org.semanticweb.owlapi.model.OWLClassExpression> getCurrentlyBestDescriptions(int nrOfDescriptions)

Parameters:

nrOfDescriptions - Limit for the number or returned descriptions.

Returns:

List<? extends EvaluatedDescription> getCurrentlyBestEvaluatedDescriptions(int nrOfDescriptions)

Return the best currently found concepts up to some maximum count (no minimality filter used).

Parameters:

nrOfDescriptions - Maximum number of descriptions returned.

Returns:

Return value is getCurrentlyBestDescriptions(nrOfDescriptions, 0.0, false).
