Sampling Content Distributed Over Graphs
Pinghui Wang, Junzhou Zhao, John C. S. Lui +2
Despite recent effort to estimate topology characteristics of large graphs (i.e., online social networks and peer-to-peer networks), little attention has been given to develop a fo…
Practical Characterization of Large Networks Using Neighborhood Information
Pinghui Wang, Bruno Ribeiro, Junzhou Zhao +3
Characterizing large online social networks (OSNs) through node querying is a challenging task. OSNs often impose severe constraints on the query rate, hence limiting the sample si…
Efficiently Estimating Motif Statistics of Large Networks
Pinghui Wang, John C. S. Lui, Bruno Ribeiro +3
Exploring statistics of locally connected subgraph patterns (also known as network motifs) has helped researchers better understand the structure and function of biological and onl…
A Peep on the Interplays between Online Video Websites and Online Social Networks
Junzhou Zhao, Pinghui Wang, Jing Tao +2
Many online video websites provide the shortcut links to facilitate the video sharing to other websites especially to the online social networks (OSNs). Such video sharing behavior…
Social Sensor Placement in Large Scale Networks: A Graph Sampling Perspective
Junzhou Zhao, John C. S. Lui, Don Towsley +2
Sensor placement for the purpose of detecting/tracking news outbreak and preventing rumor spreading is a challenging problem in a large scale online social network (OSN). This prob…
