获取给定DBpedia类别的属性

Question

I'm trying to get skos:broader of a given DBpedia category, but it gives me a null result.

This is my SPARQL request:

  select ?value where { 
     <http://dbpedia.org/page/Category:Watches> skos:broader ?value 
      }

Answer 1

The URI for DBpedia resources is http://dbpedia.org/resource/<title> , it's not http://dbpedia.org/page/<title> , that's the URL of the DBpedia page describing the resource.

So, your query should be:

select ?value where { 
  <http://dbpedia.org/resource/Category:Watches> skos:broader ?value 
}

Or shorter:

select ?value where { 
  dbc:Watches skos:broader ?value 
}
