Use of the Bleu metric to assess the naturality of the text of linguistic stegosystems

The article presents the results of a study of the use of the BLEU metric for evaluating the naturalness of the text of linguistic stegosystems. Two methods of embedding additional information are considered: the method of replacing synonyms and the method of rearranging words in a sentence. The study compares text estimates using the BLEU metric for various stegopreformations of the text, and also assesses the impact of changes made by the stegosystem on the value of the BLEU metric in the calculation. The reliability of the BLEU metric as a method of text analysis in the case of various methods of embedding is estimated.
