Interface SimilarityOperatorInterface

All Known Implementing Classes:

SimilarityOperator

public interface SimilarityOperatorInterface

An interface for classes that provides an operator to calculate the similarity between 2 fuzzy values. By default the SimilarityByArea operator (ratio of area of intersection to area of union of the fuzzy values) is used.

SimilarityByAreaOperator, SimilarityByPossibilityOperator

Method Summary

double

similarity(nrc.fuzzy.FuzzyValue fuzzyValue1, nrc.fuzzy.FuzzyValue fuzzyValue2) Classes that implement the SimilarityOperatorInterface must provide a similarity method that accepts 2 FuzzyValue objects and returns the measure of the similarity between them.

Method Detail

similarity

public double similarity(nrc.fuzzy.FuzzyValue fuzzyValue1,
                         nrc.fuzzy.FuzzyValue fuzzyValue2)
                  throws IncompatibleFuzzyValuesException

Classes that implement the SimilarityOperatorInterface must provide a similarity method that accepts 2 FuzzyValue objects and returns the measure of the similarity between them.

Parameters:

fuzzyValue1 -

fuzzyValue2 -

Returns:

double that is the result of applying the operator to the 2 values (the similarity measure)
