Tracking Top-K Influential Vertices in Dynamic Networks
Yu Yang, Zhefeng Wang, Tianyuan Jin +2
Influence propagation in networks has enjoyed fruitful applications and has been extensively studied in literature. However, only very limited preliminary studies tackled the chall…
Mining Density Contrast Subgraphs
Yu Yang, Lingyang Chu, Yanyan Zhang +3
Dense subgraph discovery is a key primitive in many graph mining applications, such as detecting communities in social networks and mining gene correlation from biological data. Mo…
Activity Maximization by Effective Information Diffusion in Social Networks
Zhefeng Wang, Yu Yang, Jian Pei +1
In a social network, even about the same information the excitements between different pairs of users are different. If you want to spread a piece of new information and maximize t…
Tracking Influential Nodes in Dynamic Networks
Yu Yang, Zhefeng Wang, Jian Pei +1
In this paper, we tackle a challenging problem inherent in a series of applications: tracking the influential nodes in dynamic networks. Specifically, we model a dynamic network as…
Information Coverage Maximization in Social Networks
Zhefeng Wang, Enhong Chen, Qi Liu +3
Social networks, due to their popularity, have been studied extensively these years. A rich body of these studies is related to influence maximization, which aims to select a set o…
