Influence Maximization in Messenger-Based Social Networks
Yuanxing Zhang,Yichong Bai,Lin Chen,Kaigui Bian,Xiaoming Li +4 more
- 01 Dec 2016
TL;DR: A novel efficient approximation algorithm that calculates the influence by looking at the user's local contribution to the information diffusion process, which scales to large datasets with provable near-optimal performance is developed.

Population Distribution Projection by Modeling Geo Homophily in Online Social Networks
Yuanxing Zhang,Zhuqi Li,Kaigui Bian,Yichong Bai,Zhi Yang,Xiaoming Li +5 more
- 06 Jul 2017
TL;DR: A geo-homophily model in OSNs to help project the population distribution in a given division of geographical regions is proposed and a three-layer theoretic framework is established: It first describes the relationship between the online message diffusion among friends in the OSN and the offline population distribution over aGiven division of regions via a Dirichlet process, and then projects the floating population across the regions.

On Diffusion-restricted Social Network: A Measurement Study of WeChat Moments
TL;DR: Wang et al. as mentioned in this paper conduct a measurement study on information diffusion in the WeChat Moments (WM) network by crawling and analyzing the spreading statistics of more than 160,000 pages that involve approximately 40 million users.

Modeling geo-homopholy in online social networks for population distribution projection
TL;DR: The authors establish a three-layered theoretic framework that first maps the online message diffusion among friends in the OSN to the offline population distribution over a given division of regions via a Dirichlet process and then projects the floating population across the regions.
