Method Detail

openOntology

public static OntModel openOntology(java.lang.String filename,
                                    java.lang.String namespace)

opens a local Ontology and returns the OntModel

Parameters:

filename - String

namespace - String

Returns:

OntModel

openSwpathoOntology

public static OntModel openSwpathoOntology()

openSwpathoOntology, opens all owl-files and returns the OntModel containing all imports as submodels Franziska & Katja: Am besten man öffnet die OWL-Files und fügt die abhängigen Ontologien als Unterontologien dazu. Auf diese Weise verhindert man lästige Exceptions, die bei uns immer aufgetreten sind, weil anscheinend Jena nicht so richtig mit den Imports klarkommt. Eigentlich sollte man das mit OntModel.getDocumentManager().setProcessImports(true) einstellen können...

Returns:

OntModel

openOntologyHTTP

public static OntModel openOntologyHTTP(java.lang.String filename,
                                        java.lang.String namespace)

openOntologyHTTP, opens Ontology over HTTP

Parameters:

filename - String

namespace - String

Returns:

OntModel

saveModel

public static void saveModel(java.lang.String outputFile,
                             OntModel m,
                             java.lang.String namespace)

writes model m to file outputFile, overwrites the file if exists

Parameters:

outputFile - String

m - OntModel

namespace - String

query

public static java.lang.String query(java.lang.String q,
                                     OntModel m)

query2

public static java.lang.String query2(java.lang.String q,
                                      OntModel m)

getIndividualCount

public static int getIndividualCount(OntModel m)

normalizeWord

public static java.lang.String normalizeWord(java.lang.String s)

normalizeString Before a query, the String is normalized, changing the first letter to lower case

Parameters:

s - String

Returns:

String

hasSuperClass

public static boolean hasSuperClass(OntClass c)

isSubclassOf

public static boolean isSubclassOf(OntClass subclass,
                                   OntClass superclass)
