使用Eclipse的Tamil中的Sparql查询结果

Question

我们正尝试在Eclipse IDE中使用Protege为我们在Tamil中创建的OWL本体执行SparQL查询。代码运行良好，但结果似乎不显示在泰米尔语中。以下是代码和输出。

import edu.stanford.smi.protegex.owl.model.OWLModel;


public class Sample {
public static void main(String[] args) throws FileNotFoundException, IOException,           NullPointerException {

try
{
    //opening owl file
    InputStream in = new FileInputStream(new  File("C:/Users/Sandhya/Desktop/Ontology/newtamil.owl"));
    Model model=ModelFactory.createMemModelMaker().createDefaultModel() ;
    model.read(in,null);       
  System.out.println(model);
   in.close();
   String queryString =
         "PREFIX pizza:   <http://www.semanticweb.org/ontologies/2013/3/newtamil.owl#> "+     

   " PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> "+
     "PREFIX owl: <http://www.w3.org/2002/07/owl#> "+
     "PREFIX xsd: <http://www.w3.org/2001/XMLSchema#> "+
     "PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> "+
     "SELECT ?subject ?object "+
     "  WHERE { ?subject rdfs:subClassOf ?object }";
    com.hp.hpl.jena.query.Query q = QueryFactory.create(queryString);
    QueryExecution qe = QueryExecutionFactory.create(q, model);
    ResultSet results = qe.execSelect();
    while (results.hasNext())
    {
        System.out.println(results.getResourceModel() );

    ResultSetFormatter.out(System.out, results, q);
    qe.close();
    }
   }catch(java.lang.NullPointerException e){ System.out.println(e);}
    catch(Exception e){
  System.out.println("Query Failed !");
    }

   }

   }

输出：

subject | object

|%E0%AE%AA%E0%AE%AA%E0%AF%80%E0%AE%BE%E0%AF%82 | %E0%AF%8D%E0%AE%A4%E0%AF%81%E0%AE%B0%E0%AE%AA |

|%E0%AE%95%E0%AF%81%E0%AE%B0%E0%AF%82%E0%AE%95%E0%AE%A4%E0%AE%AA | %E0%AF%8D%E0%AE%A4%E0%AF%81%E0%AE%B0%E0%AE%AA |

我们想让它用泰米尔语展示。我们还安装了unicode，并将输出重定向到一个文本文件中，然后进行了检查，但它仍然没有给出预期的结果。提前谢谢。

Jena以UTF-8格式打印。

看起来数据已经被%编码了。
