Method Details

getWeight

public double getWeight(String attributeName)
                 throws ProCAKENameNotFoundException

Specified by:

getWeight in interface SMAggregateWeighted

Returns:

double the weight of the given attribute. If the weight is not set, the default weight 1.0 will be returned.

Throws:

ProCAKENameNotFoundException

setWeight

public void setWeight(String attributeName,
 double weight)
               throws ProCAKENameNotFoundException

Specified by:

setWeight in interface SMAggregateWeighted

Parameters:

attributeName - is the name of the attribute whos weight should be set

weight - is the weight of the attribute. The values will normalized automatically.

Throws:

ProCAKENameNotFoundException - if the attribute not exists

getUserSimWeightsNormalized

public Map<String,Double> getUserSimWeightsNormalized(AggregateObject dataObject)

isEveryUserSimWeightZero

public boolean isEveryUserSimWeightZero(Map<String,Double> weights)

getDefaultWeight

public double getDefaultWeight()

Specified by:

getDefaultWeight in interface SMAggregateWeighted

Returns:

default weight

setDefaultWeight

public void setDefaultWeight(double defaultWeight)

Specified by:

setDefaultWeight in interface SMAggregateWeighted

Parameters:

defaultWeight - is the default weight for each attribute, which hasn't an own weight

initializeBasedOn

protected void initializeBasedOn(SimilarityMeasure base)

Description copied from class: SimilarityMeasureImpl

Initialize measure based on existing instance

Overrides:

initializeBasedOn in class SMAggregateImpl

Parameters:

base - similarity measure to base on

@Nullable
protected @Nullable SimilarityImpl validateQueryNotEmpty(DataObject queryObject,
 DataObject caseObject)

getAttributeWeights

public Map<String,Double> getAttributeWeights()

Specified by:

getAttributeWeights in interface SMAggregateWeighted

Returns:

attribute weight map
