Hi all!
I wonder how can I get an exact mapping for the literal "1950" using
the following sparql query with bif:contains:
WHY I CAN'T GET THE EXACT MAPPINGS FOR "1950"
SELECT DISTINCT ?s ?o FROM <http://dbpedia.org> WHERE {?s ?p ?
o.FILTER( <bif:contains>(?o, '"1950"') && isLiteral(?o) && ( str(?p) !
= rdfs:label || str(?p) != foaf:name && ( ?o='1950')
))}
I get 1950's, 1950-1952, 1950-present, etc
But I don't get "1950" as for example in the instance:
http://dbpedia.org/page/Zumtobel_Lighting_Group (dbprop:foundation
1950 (xsd:integer))
Many thanks!!!
