  de.hpi.fgis.dude.similarityfunction.contentbased.calculationstrategy.AverageArrayArrayStrategy

All Implemented Interfaces:

CalculationStrategy<JsonArray,JsonArray>

public class AverageArrayArrayStrategy
extends Object
implements CalculationStrategy<JsonArray,JsonArray>

Calculates the average similarity of the arrays' elements (e.g. the first element of array #1 is compared with the first element of array #2, the second elements are compared with each other etc.). The similarities are added to each other and the over-all sum is divided by the size of the larger array.
