java.lang.Object

org.dkpro.statistics.agreement.distance.MASISetAnnotationDistanceFunction

All Implemented Interfaces:

IDistanceFunction

public class MASISetAnnotationDistanceFunction
extends Object
implements IDistanceFunction

Distance function for set-valued annotation studies based on the definition of Passonneau's (2006) MASI (Measuring Agreement on Set-valued Items). The measure is an improved version of SetAnnotationDistanceFunction
