Package de.dfki.mycbr.core.similarity

Contains standard classes to maintain similarity functions for attribute descriptions (local similarity functions) and concepts (amalgamation functions).

Description

Interface Summary

ISimFct	Has to be implemented by each similarity function such that one can always compute similarity of two attributes without casting the ISimFct to a specific object.
TaxonomyNode	Represents nodes in the taxonomy used by TaxonomyFct to compute similarities of symbols.

Class Summary

AdvancedDoubleFct	Used for calculating similarities of DoubleAttribute objects.
AdvancedFloatFct	Used for calculating similarities of FloatAttribute objects.
AdvancedIntegerFct	Used for calculating similarities of IntegerAttribute objects.
AmalgamationFct	This function is used to compute similarity of to ConceptAttribute objects.
DateFct	Not implemented yet.
DoubleFct	Calculates the similarity of DoubleAttribute objects.
FloatFct	Calculates the similarity of FloatAttribute objects.
IntegerFct	Calculates the similarity of IntegerAttribute objects.
IntervalFct	Not implemented yet.
NumberFct	Defines how to compute the similarity of two integers, floats or doubles.
OrderedSymbolFct	This function provides a linear order of the known symbol attributes for the given description.
Similarity	Represents similarity values.
SpecialFct	Special values such as "undefined" can be used as values for any attribute description.
StringFct	Calculates the similarity of two strings for a given description.
SymbolFct	Holds the similarity of the known attributes for the given description in a two dimensional array (table).
Taxonomy	Represents the data structure used for taxonomy similarity functions.
TaxonomyFct	Similarity function for symbol descriptions.

Enum Summary

FunctionEnum

Lists the functions types which can be used to calculate the similarity of attributes of the respective description.

Package de.dfki.mycbr.core.similarity Description

Contains standard classes to maintain similarity functions for attribute descriptions (local similarity functions) and concepts (amalgamation functions).

The model of the myCBR project allows definition of several similarity functions for an attribute description. Each attribute description (concept) holds a collection of known similarity (amalgamation) functions. Each similarity value is an object of class Similarity.
