SimilarityValuatorImpl

public SimilarityValuatorImpl(SimilarityModel simModel)

Method Details

getSimilarityMeasure

public SimilarityMeasure getSimilarityMeasure(DataObject query,
 DataObject object)

Description copied from interface: SimilarityValuator

Returns the appropriate similarity measure for the common parent class of both given data objects.

Specified by:

getSimilarityMeasure in interface SimilarityValuator

Parameters:

query - the query object

object - the case object

Returns:

the similarity measure for the common data class

computeSimilarity

public Similarity computeSimilarity(DataObject query,
 DataObject object)

Description copied from interface: SimilarityValuator

Computes the similarity between a query and a case.

Specified by:

computeSimilarity in interface SimilarityValuator

Parameters:

query - The query DataObject.

object - The case DataObject.

Returns:

the similarity value, if no applicable similarity measure exists, an invalid Similarity will be returned.

computeSimilarity

public Similarity computeSimilarity(DataObject queryObject,
 DataObject caseObject,
 DataClass commonClass)

Description copied from interface: SimilarityValuator

Computes the similarity between a query and a case for the given common data class.

Specified by:

computeSimilarity in interface SimilarityValuator

Parameters:

queryObject - The query DataObject.

caseObject - The case DataObject.

commonClass - The common parent DataClass that should be used.

Returns:

the similarity value, if no applicable similarity measure exists, an invalid Similarity will be returned.

computeSimilarity

public Similarity computeSimilarity(DataObject queryObject,
 DataObject caseObject,
 String similarityMeasureStr)

Description copied from interface: SimilarityValuator

Computes the similarity between a queryObject and a caseObject based on the similarityMeasure

Specified by:

computeSimilarity in interface SimilarityValuator

similarityMeasureStr - if null, SimilarityValuator.computeSimilarity(DataObject, DataObject) is used, else the similarity with the given name is used.

Returns:

the similarity value, if no similarity measure with that name exists, an invalid Similarity will be returned.

getSimilarityModel

public SimilarityModel getSimilarityModel()

Description copied from interface: SimilarityValuator

The SimilarityModel that is used for the computation.

Specified by:

getSimilarityModel in interface SimilarityValuator

Returns:

the used SimilarityModel
