Ljubisa Bojic, Alexander Felfernig, Bojana Dinic +4
Social media platforms mediate how billions form opinions and engage with public discourse. As autonomous AI agents increasingly participate in these spaces, understanding their be…
Towards Simulating Social Media Users with LLMs: Evaluating the Operational Validity of Conditioned Comment Prediction
Nils Schwager, Simon Münker, Alistair Plum +1
The transition of Large Language Models (LLMs) from exploratory tools to active "silicon subjects" in social science lacks extensive validation of operational validity. This study…
Next Reply Prediction X Dataset: Linguistic Discrepancies in Naively Generated Content
Simon Münker, Nils Schwager, Kai Kugler +2
The increasing use of Large Language Models (LLMs) as proxies for human participants in social science research presents a promising, yet methodologically risky, paradigm shift. Wh…
