CTRUST project, in collaboration with EUROCC4SEE project, organized a two-day hybrid workshop titled CTRUST Workshop Trust: Foundation, Measurement, and Relevance on collective trust at the Institute of Physics Belgrade on 22 and 23 December 2025. The event brought together researchers from physics, computer science, social sciences, psychology, and artificial intelligence to discuss interdisciplinary approaches to studying collective trust in online and social systems.
The workshop examined how trust emerges, evolves, and can be measured in complex social systems, with a particular focus on digital and online communities. A central theme was the integration of computational methods, such as natural language processing, network science, agent-based modeling, and large-language model simulations, with empirical social data. Presentations covered topics including language technologies and text embeddings for Serbian, AI-driven narrative and misinformation analysis, large-language model based social simulations, and the use of synthetic agents and large language models to study social behavior. Several contributions introduced new datasets, modeling frameworks, and validation approaches for analyzing trust dynamics at scale.
In addition, the workshop addressed psychological and behavioral aspects of online interaction, including the roles of personality traits, emotions, and nonverbal communication, alongside advanced mathematical and network-theoretic approaches to modeling collective cognition and higher-order social structures. Overall, the event highlighted the importance of interdisciplinary collaboration and high-performance computing - enabled methods in advancing the scientific understanding of trust as a complex social phenomenon, while fostering exchange across theoretical, methodological, and applied perspectives within the computational social science research community.
