Method Detail

toIntArray

public static <T> int[] toIntArray(java.util.List<T> ngram,
                                   ArrayEncodedNgramLanguageModel<T> lm)

toObjectList

public static <T> java.util.List<T> toObjectList(int[] ngram,
                                                 ArrayEncodedNgramLanguageModel<T> lm)

sample

public static <W> java.util.List<W> sample(java.util.Random random,
                                           NgramLanguageModel<W> lm)

Samples from this language model. This is not meant to be particularly efficient

Parameters:

random -

Returns:

sample

public static <W> java.util.List<W> sample(java.util.Random random,
                                           NgramLanguageModel<W> lm,
                                           double sampleTemperature)

getDistributionOverNextWords

public static <W> Counter<W> getDistributionOverNextWords(NgramLanguageModel<W> lm,
                                                          java.util.List<W> context)

Builds a distribution over next possible words given the context. Context can be of any length, but only at most lm.getLmOrder() - 1 words are actually used.

Type Parameters:

W -

Parameters:

lm -

context -
