 7. The parameter `-cn` is always followed by two arguments (Example: `-cn year lm_ns_year`). The first is used to specifie how the n-grams are counted. It can be set to "year", "mont_year", "speaker" or "speech". N-grams will then be count by year, speaker and so on. The second argument is a user specified string to identify from what kind of protocols the n-grams have been calculated. The string "lm_ns_year" for example describes that the input protocols have been lemmatized (lm) and contain no stop words (ns). The last part (year) specifies that the n-grams have been calculated by year.
