Method Detail

printHierarchyTree

public static void printHierarchyTree(java.lang.String taxonURL,
                                      java.lang.String rootConceptURI,
                                      float k_factor)

Utility method printing the taxonomy tree on screen including milestones. Works only with the build-in ExpMilestCalc.

Parameters:

taxonURL - location of the taxonomy file (RDF or OWL)

rootConceptURI - URI of the taxonomy's root concept

printMatchingResult

public static void printMatchingResult(MatchingResult mr)

Prints the matching result out

Parameters:

mr - - object returned by the engine

printHierarchyTree

private static void printHierarchyTree(com.hp.hpl.jena.rdf.model.Model m,
                                       com.hp.hpl.jena.rdf.model.Resource r,
                                       int level,
                                       float k_factor)

Recursive method used to iterate through a taxonomy

Parameters:

m - Jena RDF model reresenting a taxonomy

r - Jena Resource from this model

level - taxonomy level

k_factor - k factor for the build-in ExpMilestCalc

multiplyUnderscore

private static java.lang.String multiplyUnderscore(int i)

Helper method used in printHierarchyTree() to mark the indentation of a concept with a series of "_ " according to its hierarchy level.

Parameters:

i - hierarchy level
