Abstract
In the present paper we consider the feasibility of using methods of almost periodic functions, wavelet analysis and Hurst self-similarity to analyze in length of time the behavior spectra of vectors defining the position of the news reports clusters in the information space. The essence of the authors approach is to apply the methods of mathematical linguistics (text markup, normalization, comment) to create a dictionary and a collection of news text messages tied to the time scale. This makes it possible to create a vector representation for each newsletter, using standard methods. It is proposed to introduce the concept of a director (a conditional axis characterizing the basic direction of all vectors) for the entire set of vectors presented in the article. Time progress in metrics (cosine of the angle) of the vectors defining the position of the clusters centers relative to directors form spectra of information processes. The analysis by the methods of almost - periodic functions, wavelet analysis and Hurst self-similarity can help identify the presence of recurrence of certain social events groups, and thus predict their possible manifestation in the future.
