Constructor Detail

FuzzyFingerprintingEncoding

public FuzzyFingerprintingEncoding()

The default constructor. Instantiates the default fuzzification scheme FuzzificationScheme#FuzzificationScheme().

FuzzyFingerprintingEncoding

public FuzzyFingerprintingEncoding(FuzzyFingerprintingEncoding.FuzzificationScheme scheme)

The explicit constructor. Initializes the encoding with the given fuzzification scheme.

Parameters:

scheme - a user defined fuzzification scheme

Method Detail

getFuzzificationScheme

public FuzzyFingerprintingEncoding.FuzzificationScheme getFuzzificationScheme()

Returns the fuzzification scheme that is applied to encode a documents vector representation to a single integer value.

Returns:

the internal fuzzification scheme

setFuzzificationScheme

public void setFuzzificationScheme(FuzzyFingerprintingEncoding.FuzzificationScheme scheme)

Sets the fuzzification scheme that is applied to encode a documents vector representation to a single integer value.

Parameters:

scheme - the user defined fuzzification scheme

hash

public java.math.BigInteger hash(Vector document)

Specified by:

hash in interface SimilarityHashFunction<Vector>
