Class ConceptPosition

java.lang.Object
  de.fuberlin.wiwiss.semmf.taxon.ConceptPosition

public class ConceptPosition
extends java.lang.Object

This class describes the position of a concept in the concept hierarchy. The concept position is indicated by the level in a concept hierarchy (the level is used to calculate the milestone of a given concept) and by a reference to the super concept (in this way all concepts create a taxonomy tree, allowing the matching engine to traverse along the path to the root concept and by these means to determine the closest common parent of two given concepts as the intersection of their paths). Note that a particular concept (at this time it only refers to BottomConcepts) may have more than one position in the hierarchy e.g. to have more than one super concept.

Constructor Detail

ConceptPosition

public ConceptPosition(int level,
                       SuperConcept sc)

Constructor.

Parameters:

level - taxonomy level

sc - reference to a SuperConcept of a concept having this position in the taxonomy tree.

Method Detail

isRoot

public boolean isRoot()

Returns:

true if this position is a position of a root concept. A root concept is located at level=0 and has not SuperConcepts.

getLevel

public int getLevel()

Returns:

the level of this concept position

getSuperConcept

public SuperConcept getSuperConcept()

Returns:

the reference to a SuperConcept of this concept position
