Survey of Inferring Information Diffusion Networks
Information diffusion can be modeled as a stochastic process over a network.However,the topology of an underlying diffusion network and the pathways of spread are often not visible in real-world scenarios.Therefore,the inference of diffusion networks becomes critical in the analysis and understanding of the diffusion process,tracking the pathways of spread,and even predicting future contagion events.There has been a surge of interest in diffusion network inference over the past few years.This paper investigates and summarizes the representative research in the field of diffusion network inference.Finally,this paper analy-zes the existing problems of diffusion network inference and provides a new perspective on this field.
