Method Details

compute

public Similarity compute(DataObject queryObject,
 DataObject caseObject,
 SimilarityValuator valuator)

Specified by:

compute in interface SimilarityMeasure

Returns:

setDiscordantParameter

public void setDiscordantParameter(double discordantParameter)

Description copied from interface: SMListCorrectness

Setting a parameter, that specifies, how the similarity is evaluated if there are more discordant than concordant pairs. By default, this parameter is set to 1.0 and decreases linearly. This means that only discordant pairs have a similarity of 1.0. The parameter can be in the interval 1.0 to 0.0.

Specified by:

setDiscordantParameter in interface SMListCorrectness

Parameters:

discordantParameter - A double parameter, which specifies the maximum similarity if only discordant pairs exists.

getDiscordantParameter

public double getDiscordantParameter()

Description copied from interface: SMListCorrectness

Returns the double parameter, which specifies the maximum similarity if only discordant pairs exists.

Specified by:

getDiscordantParameter in interface SMListCorrectness

Returns:

A double parameter, which specifies the maximum similarity if only discordant pairs exists.

isSimilarityFor

public boolean isSimilarityFor(DataClass dataclass,
 String orderName)

Overrides:

isSimilarityFor in class SMCollectionImpl

getSystemName

public String getSystemName()

Description copied from interface: SimilarityMeasure

The system name can be used to distinguish the similarity measures. Each similarity measure that can be instantiated contains a static final field called NAME representing the system name, e.g., SMAggregateEuclidian.NAME

The system name must also be given during initialization, see SimilarityModel.createSimilarityMeasure(String, DataClass).

Specified by:

getSystemName in interface SimilarityMeasure

Returns:

The system name of the similarity measure. This is equal to SimilarityMeasure.NAME.
