Studying the processes of information propagation in Youtube video hosting social network

The purpose of the work is to explore the influence of structural and topological features of the YouTube video hosting social network on the processes of information propagation in YouTube. In the course of the work, data were collected to build a fragment of a network of YouTube channels, the basic characteristics of the network and centrality indicators were calculated and analyzed. Special attention is paid to the study of the topological features of the network, including community structures and core-periphery. The study used a propagation model that takes into account the identified properties of the network. The influence of the community structure on the processes of information propagation is studied, and the role of significant nodes on the scale and time of information propagation is investigated. The results obtained can be the basis for solving the problems of finding superpropagators, blocking negative influence, forming sets of the most influential nodes for solving the problems of propagation and blocking.
