Dissemination models proposed in social media are based for the most part on epidemiological hypotheses and not on the observation of real data to describe the characteristics of the diffusion. Such models cannot faithfully reproduce the phenomenon of diffusion because they do not consider the observed factors that may influence this phenomenon. Our approach is innovative because we consider the populations of the countries and that it consists in identifying in addition to the number of populations reached, the geographical radius of influence around these populations, the moment of diffusion of the information, the duration of the diffusion and the country to which these populations belong knowing the population at the origin of the information and its theme.
