public class MetricSDAECS
extends AbstractMetricSingleDimensional

This class provides an implementation of the (normalized) average equivalence class size metric. We dont normailze the metric as proposed in the original publication [1], as this would only be possible for k-anonymity. [1] LeFevre K, DeWitt DJ, Ramakrishnan R. Mondrian Multidimensional K-Anonymity. IEEE; 2006:25-25.

Returns an instance of the maximal value.

Setzt außer Kraft:

createMaxInformationLoss in Klasse AbstractMetricSingleDimensional

Gibt zurück:

createMinInformationLoss

public ILSingleDimensional createMinInformationLoss()

Beschreibung aus Klasse kopiert: Metric

Returns an instance of the minimal value.

Setzt außer Kraft:

createMinInformationLoss in Klasse AbstractMetricSingleDimensional

Gibt zurück:

getConfiguration

public MetricConfiguration getConfiguration()

Returns the configuration of this metric.

Setzt außer Kraft:

getConfiguration in Klasse Metric<ILSingleDimensional>

Gibt zurück:

getScore

public ILScore getScore(Transformation<?> node,
 HashGroupify groupify)

Beschreibung aus Klasse kopiert: Metric

Calculates the score. Note: All score functions are expected to return a score value divided by the sensitivity of the score function.

Setzt außer Kraft:

getScore in Klasse Metric<ILSingleDimensional>

Parameter:

node -

groupify -

Gibt zurück:

isGSFactorSupported

public boolean isGSFactorSupported()

Beschreibung aus Klasse kopiert: Metric

Returns whether a generalization/suppression factor is supported

Setzt außer Kraft:

isGSFactorSupported in Klasse Metric<ILSingleDimensional>

Gibt zurück:

toString

public String toString()

Beschreibung aus Klasse kopiert: Metric

Returns the name of metric.

Setzt außer Kraft:

getInformationLossInternal

protected ILSingleDimensionalWithBound getInformationLossInternal(Transformation<?> node,
 HashGroupify g)

Beschreibung aus Klasse kopiert: Metric

Evaluates the metric for the given node.

Angegeben von:

getInformationLossInternal in Klasse Metric<ILSingleDimensional>

Parameter:

node - The node for which to compute the information loss

g - The groupify operator of the previous check

Gibt zurück:

the double

getInformationLossInternal

protected ILSingleDimensionalWithBound getInformationLossInternal(Transformation<?> node,
 HashGroupifyEntry entry)

Beschreibung aus Klasse kopiert: Metric

Returns the information loss that would be induced by suppressing the given entry. The loss is not necessarily consistent with the loss that is computed by getInformationLoss(node, groupify) but is guaranteed to be comparable for different entries from the same groupify operator.

Angegeben von:

getInformationLossInternal in Klasse Metric<ILSingleDimensional>

Parameter:

entry -

Gibt zurück:

getLowerBoundInternal

protected ILSingleDimensional getLowerBoundInternal(Transformation<?> node)

Beschreibung aus Klasse kopiert: Metric

Returns a lower bound for the information loss for the given node. This can be used to expose the results of monotonic shares of a metric, which can significantly speed-up the anonymization process. If no such metric exists, simply return null.

Angegeben von:

getLowerBoundInternal in Klasse Metric<ILSingleDimensional>

Parameter:

node -

Gibt zurück:

getLowerBoundInternal

protected ILSingleDimensional getLowerBoundInternal(Transformation<?> node,
 HashGroupify groupify)

Beschreibung aus Klasse kopiert: Metric

Returns a lower bound for the information loss for the given node. This can be used to expose the results of monotonic shares of a metric, which can significantly speed-up the anonymization process. If no such metric exists, simply return null.

This variant of the method allows computing a monotonic share based on a groupified data representation. IMPORTANT NOTE: The groups may not have been classified correctly when the method is called, i.e., HashGroupifyEntry.isNotOutlier may not be set correctly!

Angegeben von:

getLowerBoundInternal in Klasse Metric<ILSingleDimensional>

Parameter:

node -

groupify -
