【问题描述】:
我已经编写了这段代码来替换对象属性值:
public void changeObjectPropertyValue(String ind, String propertyFragment, String newValueFragment) {
OWLNamedIndividual individualToReplaceValueOn = factory.getOWLNamedIndividual(prefix + ind);
OWLNamedIndividual newValueInd = factory.getOWLNamedIndividual(prefix + newValueFragment);
OWLObjectProperty theObjectProperty = factory.getOWLObjectProperty(prefix + propertyFragment);
OWLIndividual theOldValue = EntitySearcher.getObjectPropertyValues(individualToReplaceValueOn, theObjectProperty, ont).findFirst().get();
OWLAxiom oldAxiom = factory.getOWLObjectPropertyAssertionAxiom(
theObjectProperty,
individualToReplaceValueOn,
theOldValue);
OWLAxiom newAxiom = factory.getOWLObjectPropertyAssertionAxiom(
theObjectProperty,
individualToReplaceValueOn,
newValueInd);
List<OWLOntologyChange> changes = new Vector<OWLOntologyChange>();
changes.add(new RemoveAxiom(ont, oldAxiom));
changes.add(new AddAxiom(ont, newAxiom));
manager.applyChanges(changes);
}
我想知道这是否是替换值的正确方法以及 OWLAPI 库中是否有方法可以做到这一点?
