Constructor Detail

JaccardSimilarityFunction

protected JaccardSimilarityFunction()

Internal constructor for Jsonable deserialization.

JaccardSimilarityFunction

public JaccardSimilarityFunction(String... defaultAttr)

Initializes the JaccardSimilarityFunction with the default tokenizer.

Parameters:

defaultAttr - The default attribute.

JaccardSimilarityFunction

public JaccardSimilarityFunction(int attrIndex,
