如何根据其基数 class 在 class 中指定个人

How to classificate individuals in a class according to its cardinality

我创建了这个 ontology,其中包含两个 classes Car、Person 和对象 属性 hasCar,其中 Person 作为域,Car 作为范围。

我想在 multiCarOwner 和 OnlyCar person 中 classify individuals(Persons),这是代表这个的 ontology:

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" class 的成员为:"individuals with exactly 1 Car."

推理的结果是偏的,因为protegé中的个体标签显示如下:

上图显示 "Bob" 个人作为 CarOwner 会员,但我希望 "bob" 成为 "onlyCar" class.

的会员

-我遇到了 OWA 问题? -有办法完成我想要的吗?

The images above show the "Bob" individual as a CarOwner member but i want that "bob" as member of "onlyCar" class. -I am facing an OWA problem ? -There is a way to accomplish what i want?

你说过鲍勃拥有一辆车,但你没有说过鲍勃没有拥有任何其他汽车。话虽如此,你不能确定他只有一辆车。您需要向 bob 添加另一个类型断言,即:

hasCar only {Car_2}

那么,既然你知道他拥有Car_2而且你知道他只拥有 Car_2,你将能够推断 bob 是

的一个元素

hasCar exactly 1 Car
