The IEEE Transactions on Computational Social Systems is dedicated to exploring the modeling, simulation, and analysis of social systems through quantitative and computational lenses. This encompasses a wide array of "systems," including interactions between people, human-machine interfaces, and machine-to-machine organizations, as well as the dynamics of social media structures. The journal publishes articles that delve into various aspects of social system dynamics, methodologies for integrating socio-cultural and behavioral factors into computational models, and the analysis of social behaviors and structures. Additionally, it features research on social network dynamics, social intelligence, and cognition, along with the design and architecture of social systems. By covering topics like socio-cultural modeling and computational behavior modeling, the journal aims to illuminate the complexities of social systems and their real-world applications, fostering a deeper understanding of these interconnected fields.
