java OWLAPI 5.1.6 SWRL规则生成和RDFXMLDocumentFormat：合并规则
什么：
我面临着我所说的问题，但可能不是
出于某些需要，我正在通过OWLAPI创建一系列swrl规则，这些规则在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，如果一个项包含所有术语，则必须将其分类为参数中的分类类
在这里，我选择了
- 番茄->；关于蔬菜
- 猴子，驴->；关于动物
如何：
我使用这个版本：
[根据Ignazio提示进行相应编辑]
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.apibinding.OWLManager;
import org.semanticweb.owlapi.formats.RDFXMLDocumentFormat;
import org.semanticweb.owlapi.model.*;
import java.io.File;
import java.util.Arrays;
import java.util.HashSet;
import java.util.List;
import java.util.Set;

public static void main(String[] args) throws Exception {
OWLOntologyManager manager = OWLManager.createOWLOntologyManager();
OWLOntology onto = manager.createOntology();
SWRLRule rule1 = createRule(manager, Arrays.asList(new String[]{"tomato"}), BASE_IRI + "#aboutVegetables");
manager.applyChange(new AddAxiom(onto, rule1));
SWRLRule rule2 = createRule(manager, Arrays.asList(new String[]{"monkey", "donkey"}), BASE_IRI + "#aboutAnimals");
manager.applyChange(new AddAxiom(onto, rule2));

OWLDocumentFormat format = new RDFXMLDocumentFormat();
manager.saveOntology(onto, format, IRI.create(output));
}
private static SWRLRule createRule(OWLOntologyManager manager,
List<String> inputWords,
String classificationClass) throws Exception {
OWLDataFactory factory = manager.getOWLDataFactory();
OWLClass classItem = factory.getOWLClass(IRI.create(CLASS_ITEM));
OWLClass classTerm = factory.getOWLClass(IRI.create(CLASS_TERM));
/**

*/
SWRLVariable varItem = factory.getSWRLVariable(IRI.create(IND_IT));
OWLObjectProperty propHasTerm = factory.getOWLObjectProperty(IRI.create(PROP_HASTERM));
Set<SWRLAtom> antecedent = new HashSet<>();
for (String term : inputWords) {
OWLNamedIndividual termInd = factory.getOWLNamedIndividual(IRI.create(BASE_IRI + "#" + term));
SWRLIndividualArgument termIndArg = factory.getSWRLIndividualArgument(termInd);
SWRLObjectPropertyAtom propAtom = factory.getSWRLObjectPropertyAtom(propHasTerm,
varItem,
termIndArg);
antecedent.add(propAtom);
antecedent.add(factory.getSWRLClassAtom(classTerm, termIndArg));
antecedent.add(factory.getSWRLClassAtom(classItem, varItem));
}
/**
* Building consequent part
*/
OWLNamedIndividual classificationIndividual = factory.getOWLNamedIndividual(IRI.create(classificationClass));
OWLObjectProperty propClassified = factory.getOWLObjectProperty(IRI.create(PROP_ISCLASSIFIED));
SWRLObjectPropertyAtom propClassifiedAtom = factory.getSWRLObjectPropertyAtom(propClassified,
varItem,
factory.getSWRLIndividualArgument(classificationIndividual));
Set<SWRLAtom> consequent = new HashSet<>();
consequent.add(propClassifiedAtom);
/**
* Create the swrl rule
*/
SWRLRule rule = factory.getSWRLRule(antecedent,
consequent);
return rule;
}
}
出了什么问题：
问题在于输出，swrl规则被合并
输出文件包含两条规则，这是可以的，但是如果您查看第一条规则，它将包含第二条规则，或者类似的内容
输出文件内容（仅限swrl规则部分）：

帮助：
显然，我看到了两种可能性：
- 我以错误的方式使用库（我已经成功地使用了此代码：/）
- 库（序列化）有问题
所以，如果您有任何提示，遇到过类似的问题，或者只是看到我错了，如果您能分享，我会很高兴：-）
谢谢
# 1 楼答案
Owlapi 3.5.0非常古老。您看到的结果似乎是RDF/XML呈现中的一个问题
尝试两件事：
改用函数语法或OWL/XML，看看这是否有帮助
使用更新的owlapi版本。您的代码应该使用5.1.6进行编译，并进行一些小的更改，其中大部分应该只针对包名
编辑：如前所述，实际使用的版本是5.1.6。所看到的问题是一个bug，已在5.1.7版中修复
# 2 楼答案
解决方案
正如Ignazio在评论中提到的，他在5.1.7版本中修复了这个bug
以前的部分解决方案（问题仍然发生，需要序列化一组更重要的规则）
只要我没有太多的时间去探索哪里出了问题，我就选择使用另一种序列化格式，因为问题并不是出现在所有可用的序列化格式中
因此，至少在这两种格式中没有出现问题：
OWLXMLDocumentFormat
RioRDFXMLDocumentFormat
