BgNgrams lists are extracted from the current version of the Bulgarian National Corpus (with a core Bulgarian part containing over 1.2 billion words). The n-grams involves both lemmas (n-gram lemma) and word forms (n-gram word form).
n-grams can be 1-grams, 2-grams, 3-grams, 4-grams, 5-grams. The n-gram language models (1-5) are in the standard ARPA text and binary format.
