  • Enclosing class:

    public static final class Normalization.NoNormalization
    extends Normalization
    Implementation used when there is no normalization.
    • Constructor Detail

      • NoNormalization

        public NoNormalization()
        Sole constructor: parameter-free
    • Method Detail

      • tfn

        public double tfn​(BasicStats stats,
                          double tf,
                          double len)
        Description copied from class: Normalization
        Returns the normalized term frequency.
        Specified by:
        tfn in class Normalization
        len - the field length.
      • explain

        public Explanation explain​(BasicStats stats,
                                   double tf,
                                   double len)
        Description copied from class: Normalization
        Returns an explanation for the normalized term frequency.

        The default normalization methods use the field length of the document and the average field length to compute the normalized term frequency. This method provides a generic explanation for such methods. Subclasses that use other statistics must override this method.

      • toString

        public String toString()
        Description copied from class: Normalization
        Subclasses must override this method to return the code of the normalization formula. Refer to the original paper for the list.
