Towards User Engagement Dynamics in Social Networks
Qingyuan Linghu, Fan Zhang, Xuemin Lin +2
The engagement of each user in a social network is an essential indicator for maintaining a sustainable service. Existing studies use the of a user to well estimate its…
Exploring Cohesive Subgraphs with Vertex Engagement and Tie Strength in Bipartite Graphs
Yizhang He, Kai Wang, Wenjie Zhang +2
We propose a novel cohesive subgraph model called -strengthened -core (denoted as -core), which is the first to consider both tie strength and vertex engagement…
Efficient Butterfly Counting for Large Bipartite Networks
Kai Wang, Xuemin Lin, Lu Qin +2
Bipartite networks are of great importance in many real-world applications. In bipartite networks, butterfly (i.e., a complete 2 x 2 biclique) is the smallest non-trivial cohesive…
When Engagement Meets Similarity: Efficient (k,r)-Core Computation on Social Networks
Fan Zhang, Ying Zhang, Lu Qin +2
In this paper, we investigate the problem of (k,r)-core which intends to find cohesive subgraphs on social networks considering both user engagement and similarity perspectives. In…
