Modeling Multi-topic Information Diffusion in Social Networks Using Latent Dirichlet Allocation and Hawkes Processes


We present in this paper a framework to model information diffusion in social networks based on linear multivariate Hawkes processes and the latent Dirichlet allocation topic model. Our model exploits the effective broadcasting times of information by users and a fuzzy scheme of information dissemination, where users broadcast information as a mixture of… (More)
