Interface SMTaxonomyNodeHeight

All Superinterfaces:

SimilarityMeasure, SMTaxonomy

All Known Implementing Classes:

SMTaxonomyNodeHeightImpl

public interface SMTaxonomyNodeHeight
extends SMTaxonomy

This measure computes the similarity between two nodes based on the height of the nodes. To calculate the similarity between two nodes the common parent of the nodes is searched and the heights of the nodes, which start with 1 for the root and increases the height for each level, are sourced. Similar to the measure for the Classic User Weighted taxonomy, there are three different strategies for the calculation of the similarity:

Strategy	Similarity sim(q,c)=
Optimistic	height(commonFather(q,c)) / minimum(height(q), height(c)
Pessimistic	height(commonFather(q,c)) / maximum(height(q), height(c)
Average	height(commonFather(q,c)) / ((height(q) + height(c))/2)
