Цель работы – вывод наблюдаемого на практике степенного закона распределения характеристик социодинамических процессов из стационарного уравнения Фоккера – Планка и проверка возможности применения нестационарного уравнения Фоккера – Планка для описания динамики процессов в социальных системах.</p></sec><sec><title>Методы</title><p>Методы. При проведении исследований были использованы методы моделирования стохастических процессов, методы и модели теории графов, инструменты и технологии объектно-ориентированного программирования для разработки систем сбора данных из массмедиа-источников, методы имитационного моделирования.</p></sec><sec><title>Результаты</title><p>Результаты. Наблюдаемое текущее состояние графа сети комментариев может быть описано с помощью вектора, элементами которого являются среднее значение коэффициента посредничества, среднее значение коэффициента кластеризации, доля пользователей в конкретном состоянии. Критическое состояние сети может быть задано базовым вектором. Зависимость от времени расстояния между базовым вектором и текущим вектором состояния образует временной ряд, значения которого можно рассматривать как «блуждающую точку», динамика перемещений которой описывается нестационарным уравнением Фоккера – Планка. Текущее состояние графа комментариев можно определить с помощью методов текстовой аналитики.</p></sec><sec><title>Выводы</title><p>Выводы. Наблюдаемый на практике степенной закон зависимости стационарной плотности вероятности распределения новостей по числу комментариев может быть получен из решения стационарного уравнения Фоккера – Планка, а нестационарное уравнение может быть использовано для описания процессов в сложных сетевых структурах. Для описания состояний сети комментариев пользователей новостных масс медиа можно использовать векторное представление. Достижение или реализация желаемых, или нежелательных состояний всей социальной сети могут быть заданы на основе базовых векторов. Решение нестационарного уравнения Фоккера – Планка позволяет получить уравнение для плотности вероятности переходов между состояниями системы в единицу времени, которые хорошо согласуются с наблюдаемыми данными. Анализ полученной модели с использованием характеристик реального временного ряда для изменения графа комментариев читателей официальной страницы в социальной сети «ВКонтакте» информационного агентства «РИА Новости» и структурных параметров графа показывает ее адекватность.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objectives</title><p>Objectives. The study aims to theoretically derive the power law observed in practice for the distribution of characteristics of sociodynamic processes from the stationary Fokker–Planck equation and apply the non-stationary Fokker–Planck equation to describe the dynamics of processes in social systems.</p></sec><sec><title>Methods</title><p>Methods. During the research, stochastic modeling methods were used along with methods and models derived from graph theory, as well as tools and technologies of object-oriented programming for the development of systems for collecting data from mass media sources, and simulation modeling approaches.</p></sec><sec><title>Results</title><p>Results. The current state of the comment network graph can be described using a vector whose elements are the average value of the mediation coefficient, the average value of the clustering coefficient, and the proportion of users in a corresponding state. The critical state of the network can be specified by the base vector. The time dependence of the distance between the base vector and the current state vector forms a time series whose values can be considered as the “wandering point” whose movement dynamics is described by the non-stationary Fokker–Planck equation. The current state of the comment graph can be determined using text analysis methods.</p></sec><sec><title>Conclusions</title><p>Conclusions. The power law observed in practice for the dependence of the stationary probability density of news distribution by the number of comments can be obtained from solving the stationary Fokker–Planck equation, while the non-stationary equation can be used to describe processes in complex network structures. The vector representation can be used to describe the comment network states of news media users. Achieving or implementing desired or not desired states of the whole social network can be specified on the basis of base vectors. By solving the non-stationary Fokker–Planck equation, an equation is obtained for the probability density of transitions between system states per unit time, which agree well with the observed data. Analysis of the resulting model using the characteristics of the real time series to change the graph of comments of users of the RIA Novosti portal and the structural parameters of the graph demonstrates its adequacy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>социальные сети</kwd><kwd>моделирование социальных процессов</kwd><kwd>сетевой граф</kwd><kwd>характеристики сетевого графа</kwd><kwd>уравнение Фоккера – Планка</kwd><kwd>мониторинг</kwd><kwd>управление</kwd><kwd>нелинейная динамика</kwd><kwd>степенной закон распределения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>social networks</kwd><kwd>modeling of social processes</kwd><kwd>network graph</kwd><kwd>network graph characteristics</kwd><kwd>Fokker–Planck equation</kwd><kwd>monitoring</kwd><kwd>management</kwd><kwd>nonlinear dynamics</kwd><kwd>power law of distribution</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского научного фонда, грант № 22-21-00109 «Разработка моделей прогнозирования динамики социальных настроений на основе анализа временных рядов текстового контента социальных сетей с использованием уравнений Фоккера – Планка и нелинейной диффузии».</funding-statement><funding-statement xml:lang="en">The study is financially supported by the Russian Science Foundation, grant No. 22-21-00109 “Development of models for forecasting the dynamics of social sentiments based on analyzing time series of text content of social networks using the Fokker–Planck equations and nonlinear diffusion.”</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Du B., Lian X., Cheng X.
