如何从HermiT输出中确定问题在本体中的位置

Question

我在门徒方面是个新手。我已经能够运行一些示例，比如pizza.owl或travel.owl。然后我打开了别人创建的本体，当我运行HermiT推理器时，我得到了以下错误：

An error occurred during reasoning: String '^(\(?\+?[0-9]*\)?)?[ \.\-])?(\(?[0-9]*\)?)?[0-9A-Z \.\-\(\)]*((x|ext|extension)? ?[0-9]*)?$' in the datatype restriction org.semanticweb.HermiT.datatypes.rdfplainliteral.RDFPlainLiteralDatatypeHandler@64cf23b2 is not a valid regular expression..

这似乎是本体论中定义的字符串有问题(但我可能错了)。关于如何确定问题在本体中的位置，有什么建议吗？

我使用的是Protege 5.5.0

谢谢!

从…

at org.semanticweb.HermiT.structural.OWLClausification$DataRangeConverter.convertDataRange(OWLClausification.java:820)

Data property的Range规范似乎有问题。因此，转到Protege中的"Data properties“选项卡，查找具有范围规范的数据属性，并删除范围规范(假设您已经复制了原始本体)。

通常，在与本体斗争时，我会从本体中删除公理，直到它一致或不给出错误。然后，我将慢慢地添加回公理，直到我再次得到一个失败。
