我正面临所谓的问题,但可能不是。
对于某些需求,我正在通过OWL API创建一系列swrl规则,将其序列化后将通过简单的文件上传添加到stardog存储库中。
例如,我修改了我的代码以生成两个非常简单的swrl规则公理:对于给定的术语列表,如果一项具有所有术语,则必须将其分类为参数中的分类类。
在这里,我选择了
我使用此版本:
[根据Ignazio提示进行了编辑]
compile group: 'net.sourceforge.owlapi', name: 'owlapi-distribution', version: '5.1.6'
所以我有类似的东西来产生swrl规则公理:

import org.semanticweb.owlapi.model.*;

consequent.add(propClassifiedAtom);
/**

SWRLRule rule = factory.getSWRLRule(antecedent,

return rule;
}
}
问题出在输出中,swrl规则被合并。
输出文件包含两个规则,没关系,但是如果您查看第一个规则,则它包含第二个规则,或者类似的东西。
输出文件内容(仅swrl规则部分):

很明显,我看到了两种可能性:
因此,如果您有任何提示,遇到类似的问题,或者只是看我怎么了,如果可以共享它,我将很高兴:-)
谢谢
答案 0 :(得分:1)
Owlapi 3.5.0很古老。您看到的结果似乎是RDF / XML渲染中的问题。
要尝试的两件事:
改用功能语法或OWL / XML,看看是否有帮助
使用较新的owlapi版本。您的代码应使用5.1.6进行编译,但要进行较小的更改,其中大多数应该仅在程序包名称上。
编辑:如前所述,实际使用的版本是5.1.6。看到的问题是一个错误,已在5.1.7版中修复。
答案 1 :(得分:0)
正如Ignazio的评论中所述,他修复了5.1.7版本中的错误
只要我没有太多时间去探索问题所在,我就会选择使用另一种序列化格式,因为并不是所有可用的序列化格式都存在这个问题...
因此,至少两种格式都没有出现此问题:
