--  如何在自己构建的本体中导入本体cyc?
我建了一个本体,现要将本体中的一些概念挂到cyc上,我用protege导入cyc,我把opencyc.owl下载到硬盘上,然后在imports中导入cyc,improted uri是http://www.owl-ontologies.com/submodel.owl,alias url是file:/c:/program files/protege_3.1/open-cyc.owl.导进去后我要将一个属性的值域定义为cyc中的一个概念,但是我找不到cyc这个本体,问题出在哪里?

google了一下 找到一个2年前的回答
可能是针对opencyc的早期版本
不知道是否适用你导入的opencyc:

Build 120 of the OWL Plugin will be able to load OpenCyc's
version http://www.cyc.com/2003/04/01/cyc

However, Protege will not be the best tool to view/edit
the details of it, because this ontology makes heavy use
of multiple typing.  Many classes have several rdf:types
and Protege can only display the first type.

Also, there are bugs in this OpenCyc version:
The property guid is declared as FunctionalProperty, but
it should be also declared as DatatypeProperty.  Otherwise
it is interpreted as rdf:Property (which is not the intention
of the authors, as far as I can tell).  Also, there is a
reference to a class http://www.w3.org/2002/07/owl#Property
which does not exist in the OWL specification (I assume they
meant ObjectProperty).  This is very critical, because thus
we cannot interpret these as properties.

Perhaps someone could notify the authors of OpenCyc about this.

ps:我最近也在想导入opencyc到protege
有什么问题能不能交流一下?

我后来把cyc的网址换成http://www.cyc.com/2004/06/04/cyc了,开始能导入,等了大概一个小时后出现了错误,
java.lang.outofmemoryerror:java heap space
后来看了看网上说的好像是内存溢出,目前仍未解决此问题.
我的qq是50246200,咱们共同讨论一下吧
