删除OWLAPI中特定类的个体

Question

removerToDeleteAlreadyAssignedInds = new OWLEntityRemover(man, Collections.singleton(target_Ontology));

OWLClass classWithAlreadyAssignedInds = factory.getOWLClass(destinationclassname,pm_Target_Ontology);
for(OWLNamedIndividual indsToDelete : classWithAlreadyAssignedInds.getIndividualsInSignature())
        {
            indsToDelete.accept(removerToDeleteAlreadyAssignedInds);
        }

        man.applyChanges(removerToDeleteAlreadyAssignedInds.getChanges());
        removerToDeleteAlreadyAssignedInds.reset();
        man.saveOntology(target_Ontology);

Answer 1

您正在对OWLClass对象使用getIndiversalsInSignature()。该对象的签名中没有个人。

如果您使用

target_Ontology.getClassAssertionAxioms(classWithAlreadyAssignedInds)

对于您的循环，您应该能够删除断言属于该类的个体。但是，有些个体可能被推断为属于该类，在这种情况下，您将不得不手动查找它们，或者使用本体上的推理器获得该类的所有实例：

OWLReasoner r... 
r.getInstances(classWithAlreadyAssignedInds, false)
