[in sources printed between 1500 and 2008 (en.wikipedia.org. ) ngram-count generates and manipulates N-gram counts, and estimates N-gram language models from them. But now we'll go into n gram frequency count which is building on top of the text pre processing, as well as we'll go through a concept called phrase mining.
