Question

我从the previous question得到了建议，并修改了来源。但是，源仍然无法正常工作。

我正在使用GraphDB（RuleSet：OWL2-RL）和SPARQL。

我有一个关于Person和Animal_Lover类的本体。如果宠物超过2只，则它们是Animal_Lover。

我该如何在本体中做到这一点？

我希望推断史密斯，成为Animal_Lover。但是此代码在OWL（或GraphDB）中不起作用。有什么问题吗？

Answer 1

我认为您要求的是OWL DL，这是GraphDB不支持的。

如何在OWL / GraphDB中推断具有两个以上属性的个人？
