OWL-API 5.1.6 SWRL规则生成和RDFXMLDocumentFormat:规则已合并

标签: java owl-api swrl

内容:

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

  • 西红柿->关于蔬菜
  • 猴子,驴-> aboutAnimals

方法:

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:

出了什么问题:

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):

帮助:

很明显,我看到了两种可能性:

  • 我使用库的方式错误(我已经成功使用了此代码:/)
  • 该库存在问题(序列化)

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

2 个答案:

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)

解决方案

正如Ignazio的评论中所述,他修复了5.1.7版本中的错误

以前的部分解决方案(无论如何,问题都发生了,但要序列化一组更重要的规则)

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:
