Interval-censored Transformer Hawkes: Detecting Information Operations using the Reaction of Social Systems
Quyu Kong, Pio Calderon, Rohit Ram +2
Social media is being increasingly weaponized by state-backed actors to elicit reactions, push narratives and sway public opinion. These are known as Information Operations (IO). T…
Slipping to the Extreme: A Mixed Method to Explain How Extreme Opinions Infiltrate Online Discussions
Quyu Kong, Emily Booth, Francesco Bailo +2
Qualitative research provides methodological guidelines for observing and studying communities and cultures on online social media platforms. However, such methods demand considera…
Contact Tracing: Computational Bounds, Limitations and Implications
Quyu Kong, Manuel Garcia-Herranz, Ivan Dotu +1
Contact tracing has been extensively studied from different perspectives in recent years. However, there is no clear indication of why this intervention has proven effective in som…
Evently: Modeling and Analyzing Reshare Cascades with Hawkes Processes
Quyu Kong, Rohit Ram, Marian-Andrei Rizoiu
Modeling online discourse dynamics is a core activity in understanding the spread of information, both offline and online, and emergent online behavior. There is currently a discon…
Describing and Predicting Online Items with Reshare Cascades via Dual Mixture Self-exciting Processes
Quyu Kong, Marian-Andrei Rizoiu, Lexing Xie
It is well-known that online behavior is long-tailed, with most cascaded actions being short and a few being very long. A prominent drawback in generative models for online events…
Modeling Information Cascades with Self-exciting Processes via Generalized Epidemic Models
Quyu Kong, Marian-Andrei Rizoiu, Lexing Xie
Epidemic models and self-exciting processes are two types of models used to describe diffusion phenomena online and offline. These models were originally developed in different sci…
