A paper on Predicting Viral News Events in Online Media by Xiaoyan Lu and Boleslaw K. Szymanski has been accepted for 2017 IEEE Workshop on Parallel and Distributed Processing for Computational Social Systems (ParSocial 2017)

Mar. 07, 2017: The information diffusion and dissemination define critical dynamics observed in large complex networks. The underlying information propagation topology, however, is often hidden or incomplete because of the lack of explicit citations of the sources. We proposed a scalable parallel algorithm to derive the node embedding to better understand the information dissemination patterns and predict emergent cascades of viral events in online media. Our algorithm infers the topic-specific output influence and the input selectivity of nodes. The parallel algorithm iteratively merges local node embedding in particular communities to obtain the global optimal results so that the processing of cascades can be significantly accelerated.
