Frequency lists extracted from the WaCky corpora. Lists of words and lemmas are provided, sorted by frequency. All the lists are in '.7z' compressed format.
Bigram lists. In order to produce cleaner (and more usable) lists, we post-processed the raw data in this way: 1) we lowercased all words, and 2) we discarded all pairs in which one or both word fields contained non-alphabetical characters, except for dashes and apostrophes (but we kept the pairs in which one of the two fields was a (single) punctuation mark).
