You can also paste http://dbpedia.org/snorql/?query=SELECT+%3Fsubject+%3Femployees+%3Fhomepage+WHERE+{%0D%0A%3Fsubject+rdf:type+%3Chttp://dbpedia.org/class/yago/Company108058098%3E.%0D%0A%3Fsubject+dbpedia2:numEmployees+%3Femployees%0D%0AFILTER+(xsd:integer(%3Femployees)+%3E%3D+50000).%0D%0A%3Fsubject+foaf:homepage+%3Fhomepage.%0D%0A}+ORDER+BY+DESC(xsd:integer(%3Femployees))%0D%0ALIMIT+20%0D%0A ... into the form at http://meyerweb.com/eric/tools/dencoder/ This gives: http://dbpedia.org/snorql/?query=SELECT ?subject ?employees ?homepage WHERE { ?subject rdf:type <http://dbpedia.org/class/yago/Company108058098>. ?subject dbpedia2:numEmployees ?employees FILTER (xsd:integer(?employees) >= 50000). ?subject foaf:homepage ?homepage. } ORDER BY DESC(xsd:integer(?employees)) LIMIT 20 Hope that helps!
