determineGenerator

public static URIGenerator determineGenerator(String recipe)

determineGenerator

public static URIGenerator determineGenerator(com.hp.hpl.jena.ontology.OntModel model)

determines the respective generator from a model currently it is only recognized if the respective class is assigned once. No heuristic is used to determine the URI Recipe, otherwise.

Parameters:

model -

Returns:

getContextBefore

public static String getContextBefore(opennlp.tools.util.Span span,
                                      String text,
                                      int contextLength)

getContextAfter

public static String getContextAfter(opennlp.tools.util.Span span,
                                     String text,
                                     int contextLength)

getFirstCharacters

public static String getFirstCharacters(String anchoredPart,
                                        int firstCharLength)

return the first characters of the anchored part urlencoded

Parameters:

anchoredPart -

firstCharLength -
