Class NormalizationH2

Normalization model in which the term frequency is inversely related to the length.

While this model is parameterless in the original article, the thesis introduces the parameterized variant. The default value for the c parameter is 1.

Note

This API is experimental and might change in incompatible ways in the next release.
