COSINE: Cognitive Online Simulation of Information Network Environments

geo-homophilyThe goal of this project is to create a cognitive agent simulation framework for studying social behavior in online information environments. We are developing a scalable, virtual laboratory, calibrated on real-world data, for studying dynamics of online social phenomena and information diffusion at different temporal resolutions and at multiple scales, from individual to community to global collective behavior.

Individual agent models within COSINE will be based on first-principles of human behavior uncovered through empirical analysis of the vast troves of online behavioral data. These models will incorporate bounded rationality and cognitive biases within models of attention. In addition, COSINE’s multi-resolution, scalable framework will enable time-resolved, massive simulations of dynamic information environments.

Key to COSINE’s success will be its ability to model complex phenomena arising in multiplex networked information environments. To achieve this, COSINE will incorporate networks into interactions between agents, thereby enabling the study of the interplay between individual behaviors and network structure, including (a) how individual traits affect where in the network individuals position themselves, (b) the information environment these positions produce, and (c) the impact this has on individual behavior. Finally, the system will be calibrated on real-word data collected from a plethora of online platforms.

Postdoctoral Fellowship: Simulation of Information Diffusion in Online Social Networks

JAN 2018 UPDATE: THIS SEARCH HAS BEEN CLOSED.

The Center for Complex Networks and Systems Research (cnets.indiana.edu) at Indiana University, Bloomington has an open postdoctoral position to study how information spreads through complex online social networks. The position funded by the DARPA program on Computational Simulation of Online Social Behavior (SocialSim). The anticipated start date for this position is January 1, 2018 (negotiable). This is an annual renewable appointment for up to 3 years subject to performance and funding. Continue reading Postdoctoral Fellowship: Simulation of Information Diffusion in Online Social Networks
