我没有使用Protégé为我的本体添加规则,而是希望使用Java或pellet将SWRL规则添加到本体。
例如,这是我要导入我的本体的规则:
[课程(?x),teacherOf(?y,?x),worksFor(?y,?z)] => [coursePresentedInUniversity(ΔX,Z)]
我想将以下代码添加到本体中:
<swrl:Imp rdf:about="#CoursePresentedInUniversityRule">
<swrl:head rdf:parseType="Collection">
<swrl:IndividualPropertyAtom>
<swrl:propertyPredicate rdf:resource="#coursePresentedInUniversity" />
<swrl:argument1 rdf:resource="#x" />
<swrl:argument2 rdf:resource="#z" />
</swrl:IndividualPropertyAtom>
</swrl:head>
<swrl:body rdf:parseType="Collection">
<swrl:ClassAtom>
<swrl:classPredicate rdf:resource="#Course" />
<swrl:argument1 rdf:resource="#x" />
</swrl:ClassAtom>
<swrl:IndividualPropertyAtom>
<swrl:propertyPredicate rdf:resource="#teacherOf" />
<swrl:argument1 rdf:resource="#y" />
<swrl:argument2 rdf:resource="#x" />
</swrl:IndividualPropertyAtom>
<swrl:IndividualPropertyAtom>
<swrl:propertyPredicate rdf:resource="#worksFor" />
<swrl:argument1 rdf:resource="#y" />
<swrl:argument2 rdf:resource="#z" />
</swrl:IndividualPropertyAtom>
</swrl:body>
</swrl:Imp>
有人能指出我的示例代码吗?
实际上,我编写了以下代码,但它没有用!
Rule mynewRule=new Rule(ruleHead,ruleBody);
PelletReasoner pelletReasoner =com.clarkparsia.pellet.owlapiv3.PelletReasonerFactory.getInstance().createReasoner(testOntology );
KnowledgeBase knowledgeBase=pelletReasoner.getKB();
knowledgeBase.addRule(mynewRule);
答案 0 :(得分:2)
Java代码的一种方法是通过OWL API - OWLDataFactory
类具有创建SWRL规则的方法,并且生成的规则可以添加到本体并保存 - 它与Protege 4使用的过程相同和5.
