比如有一个ttl格式的文件名为cco.ttl
package com.jena; import java.io.InputStream; import com.hp.hpl.jena.rdf.model.Model;
import com.hp.hpl.jena.rdf.model.ModelFactory;
import com.hp.hpl.jena.rdf.model.RDFNode;
import com.hp.hpl.jena.rdf.model.Resource;
import com.hp.hpl.jena.rdf.model.Statement;
import com.hp.hpl.jena.rdf.model.StmtIterator;
import com.hp.hpl.jena.util.FileManager; public class test
{
public static void main(String args[])
{
//String inputFileName = "E:\\Pattern Mining\\test.rdf";
//String inputFileName = "E:\\Pattern Mining\\test.nt";
String inputFileName = "E:\\ChEMBL\\cco.ttl"; Model model = ModelFactory.createDefaultModel(); InputStream in = FileManager.get().open(inputFileName);
if (in == null)
{
throw new IllegalArgumentException("File: " + inputFileName + " not found");
} //model.read(in, "","RDF/XML");//根据文件格式选用参数即可解析不同类型
//model.read(in, "","N3");
model.read(in, "","TTL");
System.out.println("开始");
// list the statements in the graph
StmtIterator iter = model.listStatements(); // print out the predicate, subject and object of each statement
while (iter.hasNext())
{
Statement stmt = iter.nextStatement(); // get next statement
//Resource subject = stmt.getSubject(); // get the subject
//Property predicate = stmt.getPredicate(); // get the predicate
//RDFNode object = stmt.getObject(); // get the object String subject = stmt.getSubject().toString(); // get the subject
String predicate = stmt.getPredicate().toString(); // get the predicate
RDFNode object = stmt.getObject(); // get the object System.out.print("主语 " + subject+"\t");
System.out.print(" 谓语 " + predicate+"\t");
if (object instanceof Resource)
{
System.out.print(" 宾语 " + object);
}
else {// object is a literal
System.out.print("宾语 \"" + object.toString() + "\"");
}
System.out.println(" .");
}
}
}
运行结果
