Subject: The Better Looking Output After the SPARQL Query in Java Code To: [email protected]
Dear Sir or Madam, I am using the SPARQL query in Java (actually, NetBeans). The query works fine, however, the results are outputted not in the nice form. The example of my code (Java) is the following: String queryString2 ="PREFIX base: < http://www.semanticweb.org/darius/ontologies/2013/6/rooms#>" + "PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns# >" + "PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>" + "PREFIX owl: <http://www.w3.org/2002/07/owl#>" + "PREFIX foaf: <http://xmlns.com/foaf/0.1/>" + "SELECT ?person ?room WHERE { ?person a base:Person. ?room a base:Room." + "FILTER regex(STR(?person), \"Ana\") }" + "ORDER BY DESC (?person)"; Query query = QueryFactory.create(queryString2); QueryExecution qe = QueryExecutionFactory.create(query, model); com.hp.hpl.jena.query.ResultSet results = qe.execSelect(); ResultSetFormatter.out(System.out, results, query); ResultSetFormatter.asText(results, query); qe.close(); I get the results in the following form: ---------------------------------------------------------------------------------------------------- | person | room | ==================================================================================================== | base:Ana | < http://www.semanticweb.org/darius/ontologies/2013/6/rooms#Rue_de_Mont_Blanc,_Geneva> | ---------------------------------------------------------------------------------------------------- Is there any possibility in SPARQL to cut or substring these additional parts ("Ana instead of "base: Ana" or "Rue_de_Mont_Blanc,_Geneva" instead of the "< http://www.semanticweb.org/darius/ontologies/2013/6/rooms#Rue_de_Mont_Blanc,_Geneva>")? I tried FILTER (SUBSTR(?person, 4)) in the query, but it did not give me the desired results. Or it is recommended to do in Java? How to do it? Thanks for any suggestions, Darius Miliauskas
