Class AsymmetricRelationship


  • public class AsymmetricRelationship
    extends Relationship
    An asymmetric relationship is one whose source and target synsets have lineages with a definite divergence point. The commonParentIndex is the index of the node in the relationship that represents this divergence point.

    For example, in finding a hypernym relationship between dog and cat, the relationship is dog -> canine -> carnivore -> feline -> cat. The ancestry of "dog" and the ancestry of "cat" diverge at "carnivore," so the common parent index is thus 2.

        private int _commonParentIndex
        The index of the node in the relationship that represents the point at which the source and target nodes' ancestries diverge.

      • getCommonParentIndex

        public int getCommonParentIndex()
      • getRelativeTargetDepth

        public int getRelativeTargetDepth()
        Get the depth of the target, from the commonParentIndex, relative to the depth of the source. If both target and source are eqidistant from the commonParentIndex, this method returns 0;
