Class NormalizationH1

Normalization model that assumes a uniform distribution of the term frequency.

While this model is parameterless in the original article, information-based models (see IBSimilarity) introduced a multiplying factor. The default value for the c parameter is 1.

Note

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