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
