我创建了这个本体,它包含两个类 Car、Person 和对象属性 hasCar,其中 Person 作为域,Car 作为范围。
我想对 multiCarOwner 和 OnlyCar 人中的个人(Persons)进行分类,这是代表这一点的本体:

但是,当我创建个人时,推理器没有给我想要的结果,我希望“OnlyCar”类具有作为成员:“具有恰好 1 辆汽车的个人”。
推理的结果是部分的,因为 protegé 中的个人选项卡显示以下内容:
上面的图片显示“Bob”个人作为 CarOwner 成员,但我希望“bob”作为“onlyCar”类的成员。
-我面临 OWA 问题?- 有办法完成我想要的吗?
