Meritocracy versus Matthew-effect: Two underlying network formation mechanisms of online social platforms
Yuchen Xu, Wenjun Mei, Ge Chen +1
With the rapid development of the internet industry, online social networks have come to play an increasingly significant role in everyday life. In recent years, content-based emer…
Structural Balance and Interpersonal Appraisals Dynamics: Beyond All-to-All and Two-Faction Networks
Wenjun Mei, Ge Chen, Noah E. Friedkin +1
Structural balance theory describes stable configurations of topologies of signed interpersonal appraisal networks. Existing models explaining the convergence of appraisal networks…
Assign and Appraise: Achieving Optimal Performance in Collaborative Teams
Elizabeth Y. Huang, Dario Paccagnan, Wenjun Mei +1
Tackling complex team problems requires understanding each team member's skills in order to devise a task assignment maximizing the team performance. This paper proposes a novel qu…
Rethinking the Micro-Foundation of Opinion Dynamics: Rich Consequences of the Weighted-Median Mechanism
Wenjun Mei, Francesco Bullo, Ge Chen +2
To identify the main mechanisms underlying complex opinion formation processes in social systems, researchers have long been exploring simple mechanistic mathematical models. Most…
Dynamic Social Balance and Convergent Appraisals via Homophily and Influence Mechanisms
Wenjun Mei, Pedro Cisneros-Velarde, Ge Chen +2
Social balance theory describes allowable and forbidden configurations of the topologies of signed directed social appraisal networks. In this paper, we propose two discrete-time d…
On the Dynamics of Deterministic Epidemic Propagation over Networks
Wenjun Mei, Shadi Mohagheghi, Sandro Zampieri +1
In this work we review a class of deterministic nonlinear models for the propagation of infectious diseases over contact networks with strongly-connected topologies. We consider ne…
Competitive Propagation: Models, Asymptotic Behavior and Multi-stage Games
Wenjun Mei, Francesco Bullo
In this paper we propose a class of propagation models for multiple competing products over a social network. We consider two propagation mechanisms: social conversion and self con…
Dynamic Models of Appraisal Networks Explaining Collective Learning
Wenjun Mei, Noah E. Friedkin, Kyle Lewis +1
This paper proposes models of learning process in teams of individuals who collectively execute a sequence of tasks and whose actions are determined by individual skill levels and…
