Syntax

public sealed class Normalization.NoNormalization : Normalization

Constructors

NoNormalization()

Sole constructor: parameter-free

Declaration

public NoNormalization()

Methods

Explain(BasicStats, float, float)

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.

Declaration

public override Explanation Explain(BasicStats stats, float tf, float len)

Parameters

Type	Name	Description
BasicStats	stats
float	tf
float	len

Returns

Type	Description
Explanation

Overrides

Normalization.Explain(BasicStats, float, float)

Tfn(BasicStats, float, float)

Returns the normalized term frequency.

Declaration

public override float Tfn(BasicStats stats, float tf, float len)

Parameters

Type	Name	Description
BasicStats	stats
float	tf
float	len	the field length.

Returns

Type	Description
float

Overrides

Normalization.Tfn(BasicStats, float, float)

ToString()

Subclasses must override this method to return the code of the normalization formula. Refer to the original paper for the list.

Declaration

public override string ToString()

Returns

Type	Description
string

Overrides

Normalization.ToString()
