Sparql 当我自定义JENA FUSEKI的规则时，表中没有可用的数据？

当我自定义JENA FUSEKI的规则时，表中没有可用的数据

• ttl是rdf:type owl:Ontology
• 和

  规则。ttl

  是我的自定义规则

删除

规则.ttl

顶部的

@前缀后，如下所示

[ruleComedian: (?p :hasActedIn ?m) (?m :hasGenre ?g) (?g :genreName '喜剧') -> (?p rdf:type :Comedian)]
[ruleInverse: (?p :hasActedIn ?m) -> (?m :hasActor ?p)]

更新1:这是
规则顶部的
@前缀

@prefix : <http://www.kgdemo.com#> .
@prefix owl: <http://www.w3.org/2002/07/owl#> .

我不知道我是否描述得很清楚


对不起，我忘记粘贴我的查询代码了

PREFIX : <http://www.kgdemo.com#>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>

SELECT ?n WHERE {
?x rdf:type :Comedian.
?x :personName ?n.
}
limit 10

它现在运行得很好

谢谢

就像一个健全的检查，数据不是空的吗
SELECT*{s？p？o}LIMIT 10
“删除rules.ttl顶部的@前缀后”-这是什么意思？您必须添加自定义前缀
：
，或者不添加？此外，您可以使用SPARQL查询检查第一个规则的前提，即
前缀：select*{p:hasActedIn？m.？m:HasGene？g.？g:genreName'喜剧' } 限制10
-这是空的吗？请仔细检查前缀声明-显然，您没有显示任何示例数据，因此，我们无法判断是否已经存在mismatch@AKSW是，
SELECT*{s？p？o}LIMIT 10
It successful！“显示10个entriesShow entriesSearch中的1到10个。”
