Constructor Detail

LanguageProfileBuilder

public LanguageProfileBuilder(@NotNull
                              @NotNull LdLocale locale)

Method Detail

ngramExtractor

public LanguageProfileBuilder ngramExtractor(@NotNull
                                             @NotNull 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.

addText

public LanguageProfileBuilder addText(java.lang.CharSequence text)

In order to use this you must set the ngramExtractor first.

addGram

public LanguageProfileBuilder addGram(java.lang.String ngram)

Shortcut for addGram(ngram, 1).

addGram

public LanguageProfileBuilder addGram(java.lang.String ngram,
                                      int frequency)

If the builder already has this ngram, the given frequency is added to the current count.

build

public LanguageProfile build()

removeNgramsWithLessFrequency

private void removeNgramsWithLessFrequency()
