Almost 70 years ago, a linguist from Harvard George Zipf formulated an empirical-mathematical law that reflects for any natural language the connection of the "rank-frequency" type: words of a very long text (in the potential of language), if lexicographically order them according to their use, then the word series with the number n, the frequency will be "almost" inversely proportional to the rank, the number n. In particular, the second most frequent word will occur twice as rarely as the first, the third - less often than the first three times, etc. Based on the application of the Zipf Law, an analysis of the web pages of sites on the subject of naturalness has been carried out.
