Subclasses of Normalisation in org.terrier.matching.models.normalisation

class	Normalisation0 This class implements an empty normalisation.

class	Normalisation2 This class implements the DFR normalisation 2.
class	Normalisation2exp This class implements the DFR normalisation 2 with natural logorithm.
class	Normalisation3 This class implements the Dirichlet Priors normalisation.
class	NormalisationB This class implements BM25's normalisation method.
class	NormalisationF This class implements an increasing density function for the frequency normalisation.
class	NormalisationJ This class implements the tf normalisation based on Jelinek-Mercer smoothing for language modelling.
class	NormalisationJN This class implements the tf normalisation based on Jelinek-Mercer smoothing for language modelling where collection model is given by document frequency instead of term frequency.
class	NormalisationP This class implements Term Frequency Normalisation via Pareto Distributions
class	NormalisationStatic This class implements a Normalisation method that forces all term frequencies to the value of the parameter.
