這個程序可能會使用推理技術向本體中添加其他獅子個體推斷出的推理，但我不知道如何解決返回的所有錯誤。的Java代碼如下：如何在eclipse上用sparql查詢推斷新的人
package paletrasi;
import com.hp.hpl.jena.rdf.model.*;
import com.hp.hpl.jena.vocabulary.RDF;
import org.apache.jena.atlas.io.IndentedWriter;
import com.hp.hpl.jena.query.*;
import com.hp.hpl.jena.rdf.model.InfModel;
import com.hp.hpl.jena.rdf.model.Model;
import com.hp.hpl.jena.rdf.model.ModelFactory;
import com.hp.hpl.jena.rdf.model.Resource;
import com.hp.hpl.jena.reasoner.Reasoner;
import org.mindswap.pellet.jena.PelletReasonerFactory;
public class jungle2
{
public static final String NL = System.getProperty("line.separator") ;
public static void main(String[] args) {
// create the simplest model there is
//
String jungle_file = "C:/Users/acer/workspace/paletrasi/src/paletrasi/junglejena.owl";
// create Pellet reasoner
Reasoner reasoner = PelletReasonerFactory.theInstance().create();
// create an empty model
Model emptyModel = ModelFactory.createDefaultModel();
//create an inferencing model using Pellet reasoner
InfModel m = ModelFactory.createInfModel(reasoner, emptyModel);
//read the file
m.read(jungle_file);
//Model m = ModelFactory.createDefaultModel();
System.out.println("We have loaded a model with no. statements = " + m.size());
String jungle ="http://www.lirmm.fr/jungle#";
String prolog1 = "PREFIX jungle: <"+jungle+">" ;
String prolog2 = "PREFIX rdf: <"+RDF.getURI()+">" ;
//Query string.
String queryString = prolog1 + NL + prolog2 + NL +
"SELECT ?individu WHERE {?individu rdf:type jungle:Lion }" ;
Query query = QueryFactory.create(queryString) ;
//Print with line numbers
query.serialize(new IndentedWriter(System.out,true)) ;
System.out.println() ;
//Create a single execution of this query, apply to a model
//which is wrapped up as a Dataset
QueryExecution qexec = QueryExecutionFactory.create(query, m) ;
//Or QueryExecutionFactory.create(queryString, model) ;
System.out.println("Les Lions : ") ;
try {
//Assumption: it’s a SELECT query.
ResultSet rs = qexec.execSelect() ;
//The order of results is undefined.
for (; rs.hasNext() ;)
{
QuerySolution rb = rs.nextSolution() ;
//Get title - variable names do not include the ’?’
RDFNode y = rb.get("individu");
System.out.print("uri : "+y+"--- ");
Resource z = (Resource) rb.getResource("individu");
System.out.println("plus simplement "+z.getLocalName());
}
}
finally
{
//QueryExecution objects should be closed to free any system resources
qexec.close() ;
}
}}
的錯誤是：

所有幫助是apreciated :)謝謝你提前 。
我已經過期＃但我得到一個exeption。請檢查編輯以查看它。 – Nanis
@ user3347859如果原始錯誤是filenotfound，那麼您不應該編輯問題並進行更改。這使得當前問題的原始問題的答案是錯誤的。 –
