The analysis of cybersecurity subject area terms based on the information diffusion model / Dmytro Lande, Olexiy Novikov, Dmytro Manko // Theoretical and Applied Cybersecurity : scientific journal. – 2022. – Vol. 4, Iss. 1. – Pp. 55–60. – Bibliogr. 6 ref.https://ela.kpi.ua/handle/123456789/55650This research describes a comparison of the information diffusion model, built on the basis of cellular automata with the real statistics the dynamics of the use of terms from the field of cybersecurity in the information flows of the Internet. The information diffusion model is used with different parameters of the intensity of the information propagation. The cross-correlation of dynamics of the dissemination of new information in the model with the dynamics of the occurrence of concepts of the real subject area has been calculated. A high correlation dynamic of the terms occurrence with the dynamics given by the model at the selected parameters is shown. The research results allow fixing the model parameters that can further perform forecasting. The advantage of the information diffusion model based on cellular automata is the simplicity and clarity of a small number of parameters, and the ability to change them in accordance with the data on the actual occurrence of special terminology in information flows. The dynamics of the information diffusion model under various parameters allows us to determine centroids for the subsequent clustering of domain terms.enModelingSubject domainCross-correlationCellular automataInformation diffusionCyber security datasetsArticlePp. 55-60https://doi.org/10.20535/tacs.2664-29132022.1.274122004.912
