假设我在Protege中创建了一些本体,并且有一个带有一些对象属性的类的实例,以及一个对象属性列表,如下图所示:
对象属性的层次结构如下:
现在,当我打开Reasoner(Hermit)时,我得到了同一个人的以下断言对象属性:
当我点击推断对象属性“dependsUp”客户的解释时,我得到:
我的问题是如何使用Java生成这个?我已经可以通过以下方式获得某个人的推断对象属性(这里不完整,但是它可以像我测试的那样工作):
for (OWLNamedIndividual namedIndividual : this.ontology.getIndividualsInSignature()) {
if (subjectName.equals(namedIndividual.getIRI().getFragment())) {
OWLObjectProperty objectProperty = fac.getOWLObjectProperty(IRI.create(propertyIRI));
NodeSet<OWLNamedIndividual> namedIndividualSet = reasoner.getObjectPropertyValues(namedIndividual ,objectProperty);
for (Node<OWLNamedIndividual> namedIndividualsInObjectPropertySet : namedIndividualSet) {
for (OWLNamedIndividual namedIndividualForObjectPropertySet : namedIndividualsInObjectPropertySet) {
for (OWLClassExpression owlClass : namedIndividualForObjectPropertySet.getTypes(this.ontology)){
if (owlClass.toString().split("#")[1].replace(">", "").equals(archiClass)) {
result.add(OWLOntologyUtils.getHumanInstanceName(this.ontology, namedIndividualForObjectPropertySet.getIRI().getFragment()));
// Result contains all the inferred object properties shown in the above pictures, so this code works. How can I access the explanation for one of the inferred object properties by the reasoner here?
}
}
}
}
}
}
答案 0 :(得分:1)
您可以使用InferredObjectPropertyAxiomGenerator
:
InferredObjectPropertyAxiomGenerator generator = new InferredObjectPropertyAxiomGenerator();
generator.createAxioms(owldatafactory, reasoner);
