我是门生的新手。我已经能够运行一些示例，例如pizza.owlor travel.owl。然后我打开了一个其他人创建的本体，当我运行 HermiT 推理器时，我收到以下错误：

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..

本体中定义的字符串似乎存在一些问题（但我可能错了）。关于如何确定问题在本体中的任何建议？

我正在使用 Protege 5.5.0

谢谢！

从

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

似乎 a 的Range规范有问题Data property。因此，转到 Protege 中的“数据属性”选项卡并查找具有范围规范的数据属性并删除范围规范（假设您已经制作了原始本体的副本）。

一般来说，在与本体作战时，我会从本体中删除公理，直到它一致或不出错。然后我会慢慢添加公理，直到我再次失败。
