Should LLM Agents Decide in Social Simulations? Comparing Finite-State and LLM-Based Decision Policies
Alejandro Buitrago López, Javier Pastor-Galindo, José A. Ruipérez-Valiente
Large language models (LLMs) are increasingly used as decision-making components in social simulations. This introduces a methodological risk: the simulation may deviate from the e…
Execution and assessment of agentic influence operations in simulated social networks
Alejandro Buitrago López, David Montoro Aguilera, Javier Pastor-Galindo +1
This article evaluates AI-enabled influence operations in synthetic social networks through controlled simulations of narrative release, amplification, and counter-messaging. We me…
Evaluating the Realism of LLM-powered Social Agents: A Case Study of Reactions to Spanish Online News
Alejandro Buitrago López, Alberto Ortega Pastor, Javier Pastor-Galindo +1
LLM-powered social agents are increasingly used to simulate online social behavior, yet their realism remains difficult to validate. Existing work has largely relied on general-pur…
Agent-based simulation of online social networks and disinformation
Alejandro Buitrago López, Alberto Ortega Pastor, David Montoro Aguilera +4
Research on online social networks (OSNs) is often hindered by platform opacity, limited access to data, and ethical constraints. Simulation offer a valuable alternative, but exist…
Synthetic generation of online social networks through homophily
Alejandro Buitrago López, Javier Pastor-Galindo, José A. Ruipérez-Valiente
Online social networks (OSNs) have become increasingly relevant for studying social behavior and information diffusion. Nevertheless, they are limited by restricted access to real…
Frameworks, Modeling and Simulations of Misinformation and Disinformation: A Systematic Literature Review
Alejandro Buitrago López, Javier Pastor-Galindo, José A. Ruipérez-Valiente
The prevalence of misinformation and disinformation poses a significant challenge in today's digital landscape. That is why several methods and tools are proposed to analyze and un…
