Method Detail

                                    NgramExtractor ngramExtractor)

minimalFrequency

public LanguageProfileBuilder minimalFrequency(int minimalFrequency)

Parameters:

minimalFrequency - 1-n, the default is 1. n-grams that occurred less often in the text are removed. This really should be set to something higher. Try to play with the number until you get a profile file of satisfying size, that produces good language detection results.

Shortcut for addGram(ngram, 1).

                             int frequency)
