[英]OWL subclass defined in turtle
I try to add a bit of ontology to a (public) RDF dataset (wordnet), specifically I need to differentiate between LexicalEntries
for Verbs and Nouns, separated as two subclasses. 我尝试向(公共)RDF数据集(wordnet)添加一些本体,特别是我需要区分动词和名词的LexicalEntries
,并分为两个子类。 Following examples on the web and in the OWL standard, I assumed that 根据网上和OWL标准中的示例,我假设
:LexicalEntryNoun a owl:Class ;
rdfs:subClassOf
[ a owl:Restriction ;
owl:onProperty wn:part_of_speech ;
owl:hasValue wn:noun
] .
should build a class LexicalEntryNoun
, but the query (in jena fuseki) 应该建立一个类LexicalEntryNoun
,但是查询(在jena fuseki中)
prefix : <http://gerastree.at/2017/litonto#>
SELECT *
WHERE {
?s a :LexicalEntryNoun.
}
gives an empty result. 给出一个空结果。 The two URI which should be returned are included in the class represented by a blank node, which stands for the restriction, but are not reported as LexicalEntryNoun
as reported in other queries. 应该返回的两个URI包含在由空白节点表示的类中,该节点代表限制,但未如其他查询中所报告的那样报告为LexicalEntryNoun
。
i am new to OWL and do not find many examples of OWL in turtle syntax. 我是OWL的新手,在乌龟语法中找不到很多OWL的示例。 Where is my error? 我的错误在哪里? Thank you for help! 谢谢你的帮助!
I constructed a very small subset of data which is loaded together with the OWL reasoner http://jena.hpl.hp.com/2003/OWLFBRuleReasoner

as already posted on the Apache Jena Users mailing list, the answer is: 正如已经发布在Apache Jena Users邮件列表上的,答案是:
Change the subclassof to an equivalence. 将subclassof更改为等效项。 Since both resources: 由于这两种资源:
http://wordnet-rdf.princeton.edu/wn31/%27s+Gravenhage-n http://wordnet-rdf.princeton.edu/wn31/%27s+Gravenhage-n
http://wordnet-rdf.princeton.edu/wn31/%27hood-n http://wordnet-rdf.princeton.edu/wn31/%27hood-n
would fall inside the :LexicalEntryNoun class and show up in his SPARQL query. 会属于:LexicalEntryNoun类,并显示在他的SPARQL查询中。
