Here's a sample query to find people for my dead pool using SPARQL and the dbpedia.

Dead Pool

PREFIX dbo: <http://dbpedia.org/ontology/>

SELECT ?name ?birth ?death ?person ?wikipedia ?occupation WHERE {
     ?person dbo:birthDate ?birth .
     ?person foaf:name ?name .
     ?person a dbo:Actor .
     OPTIONAL {?person dbo:deathDate ?death .}
     OPTIONAL {?person dbpprop:dateOfDeath ?death2 .}
     FILTER (?birth < "1950-01-01"^^xsd:date)
     FILTER (?birth > "1890-01-01"^^xsd:date)
     FILTER (!bound(?death))
     FILTER (!bound(?death2))
}
ORDER BY asc(?birth)
