我有查询 -

#select count(DISTINCT ?instance) # The number of suitable instances
#select DISTINCT ?instance ?type # Full Ground-truth dataset
select DISTINCT ?instance ?domain ?range ?subClassOf # Full Algorithm input dataset (sampling might be required)
where {
?instance rdf:type ?type;
rdfs:domain ?domain;
rdfs:range ?range;
rdfs:subClassOf* ?subClassOf.
}
ORDER BY ?instance
- 返回具有type
,domain
和range
属性的所有三元组。结果集就像 -
