如何在 OWL / GraphDB 中推断具有 2 个以上属性的个体？

Question

我得到了the previous question 的建议并修改了源代码。但是，源仍然无法正常工作。

我正在使用 GraphDB(RuleSet: OWL2-RL) 和 SPARQL。

我有一个包含 Person 和 Animal_Lover 类的本体。如果人们拥有超过 2 只宠物，则他们是 Animal_Lover。

如何在我的本体中做到这一点？

我希望史密斯被推断并成为 Animal_Lover。但是此代码在 OWL（或 GraphDB）中不起作用。有什么问题？

Answer 1

我认为您要求的内容属于 OWL DL，GraphDB 不支持。
