## Field Documentation

int32(* ngram_funcs_s::add_ug)(ngram_model_t *model, int32 wid, int32 lweight)

Implementation-specific function for adding unigrams.

This function updates the internal structures of a language model to add the given unigram with the given weight (defined as a log-factor applied to the uniform distribution). This includes reallocating or otherwise resizing the set of unigrams.

Returns
  The language model score (not raw log-probability) of the new word, or 0 for failure.
