Method Detail

score

public double score(Alignment<R,N> alignment)

Description copied from interface: RelSetSimilarity

Scores the similarity of two relation sets that are related to each other by the alignment given as input. This score is based on the Jaccard Coefficient.

Returns:

the similarity score for the two relation sets under the given alignment

scoreDice

public double scoreDice(Alignment<R,N> alignment)

Description copied from interface: RelSetSimilarity

Scores the similarity of two relation sets that are related to each other by the alignment given as input. This score is based on the Dice Coefficient.

Returns:

the similarity score for the two relation sets under the given alignment

getName

public String getName()

Description copied from class: AbstractRelSetSimilarity

Standard method for the name of a similarity. Simply returns the class name.

Specified by:

getName in interface RelSetSimilarity<R extends RelSet<M,N>,M extends IEntityModel<N>,N extends IEntity>

Overrides:

getName in class AbstractRelSetSimilarity<R extends RelSet<M,N>,M extends IEntityModel<N>,N extends IEntity>

setWeights

public void setWeights(double weightExSim,
              double weightSoSim,
              double weightInSim,
              double weightESSim,
              double weightEISim)

Set weights for aggregation of similarities.

Parameters:

weightExSim - weight for @ExclusivenessSimilarity

weightSoSim - weight for @OrderSimilarity

weightInSim - weight for @InterleavingSimilarity

weightESSim - weight for @ExtendedOrderSimilarity

weightEISim - weight for @ExtendedInterleavingSimilarity
