Who Shapes Brazil's Vaccine Debate? Semi-Supervised Modeling of Stance and Polarization in YouTube's Media Ecosystem
★★★★★
significance 2/5
This study utilizes a semi-supervised stance detection framework to analyze 1.4 million YouTube comments regarding vaccine discourse in Brazil. The research tracks how pro- and anti-vaccine narratives evolve and polarize within the digital media ecosystem over time.
Why it matters
Understanding how automated systems track and amplify polarized social narratives is critical as LLMs increasingly interface with real-world misinformation loops.
