隐士和Owlapi检索对象财产断言

Question

我尝试从理由程序(Hermit 1.3.8.4(和Owlapi(3.4.10(中检索属性主张。在这张照片中，我想检索" Israndfather Sandro，Israndfather Sergio"。

我尝试使用Ignazio答案：https：//stackoverflow.com/a/37497541/3760251

以horridge示例，但是owl api更改了签名，我不知道该如何使用它。https://www.javatips.net/api/owl-master/owlapi-master/tools/src/main/java/java/org/semanticweb/semanticweb/owlapi/itil/inferredsubobsptrredsubobsptropertpropertyaxiomgenerator.java

因此，如果您有一个来自sewredobjectPropertyaxiomgenerator的Addaxioms方法的示例，我会很感激。

pefleRedObjectPropertyaxiomgenerator generator = new celebredobjectPropertyaxiomgenerator(({ @Override 受保护的void Addaxioms(猫头鹰实体，猫头鹰推理器，owldatafactory dataFactory，设置结果({ }}

谢谢，

我从Ignazio中找到了一个很棒的代码：

我已经对您的代码进行了较小的更改，并使用Owlapi 4.3.1-Snapshot和Hermit和Hermit 1.3.8.431-Snapshot(这些版本包含第646页中详细介绍的修复程序(
