我在使用HermiT推理器庫時遇到問題。使用HermiT打印本體的層次結構
有沒有人瞭解我在這裏做錯了？
public static void main(String[] args) {
try {
// First, we create an OWLOntologyManager object. The manager will load and
// save ontologies.
OWLOntologyManager manager=OWLManager.createOWLOntologyManager();
// Now, we create the file from which the ontology will be loaded.
File inputOntologyFile = new File("SchoolESTGExample.owl");
// We use the OWL API to load the ontology.
OWLOntology ontology=manager.loadOntologyFromOntologyDocument(inputOntologyFile);
// Now we can start and create the reasoner. Here we create an instance of HermiT
// OWLReasonerFactory reasonerFactory = new StructuralReasonerFactory();
//OWLReasoner owlReasoner = reasonerFactory.createReasoner(ontology);
Reasoner reasoner = new Reasoner(ontology);
reasoner.precomputeInferences();
// We can determine if the ontology is actually consistent
if (reasoner.isConsistent()) {
// Now we create an output stream that HermiT can use to write the axioms. The output stream is
// a wrapper around the file into which the axioms are written.
File prettyPrintHierarchyFile=new File("prettyPrint.owl");
if (!prettyPrintHierarchyFile.exists())
prettyPrintHierarchyFile.createNewFile();
// turn to an absolute file, so that we can write to it
prettyPrintHierarchyFile=prettyPrintHierarchyFile.getAbsoluteFile();
BufferedOutputStream prettyPrintHierarchyStreamOut=new BufferedOutputStream(new FileOutputStream(prettyPrintHierarchyFile));
// The output stream is wrapped into a print write with autoflush.
PrintWriter output=new PrintWriter(prettyPrintHierarchyStreamOut,true);
// Now we let HermiT pretty print the hierarchies. Since all parameters are set to true,
// HermiT will print the class and the object property and the data property hierarchy.
long t=System.currentTimeMillis();
t=System.currentTimeMillis()-t;
reasoner.printHierarchies(output, true, true, true);
// Now save a copy in OWL/XML format
//File f = new File("example.xml");
//IRI documentIRI2 = IRI.create(f);
//manager.saveOntology(school, new OWLXMLOntologyFormat(), documentIRI2);
//System.out.println("Ontology saved in XML format.");
} else {
System.out.println("Ontology malformed.");
}
// Remove the ontology from the manager
//manager.removeOntology(ontology);
} catch (OWLOntologyCreationException | IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
