Sparql MULTIPLE 不存在条件
Sparql MULTIPLE not exists condition
我正在执行一个 Sparql 查询,returns 关键字 apple
不属于特定子类的所有 URI Species
select distinct ?s
where
{
?s a owl:Thing . ?s rdfs:label ?label .
filter(langmatches(lang(?label), 'en')) ?label bif:contains '"apple"' .
filter not exists {?s rdf:type/rdfs:subClassOf* dbo:Species }
}
我想包含更多子类。我想包含许多子类,所以我想像这样过滤掉:
filter not exists {?s rdf:type/rdfs:subClassOf* dbo:Species
和 filter not exists {?s rdf:type/rdfs:subClassOf* dbo:Organisation
和 filter not exists {?s rdf:type/rdfs:subClassOf* dbo:SomeOtherSubclass
如何将多个 AND 链接在一起?
你可以这样做:
FILTER NOT EXISTS {
VALUES ?clazz { dbo:Species dbo:Organisation dbo:SomeOtherSubclass }
?s rdf:type/rdfs:subClassOf* ?clazz.
}
尽管无法保证其性能如何。
