Researchers have developed a new hierarchical prompting method called HiPP to improve propaganda detection in social media texts. This method involves predicting fine-grained propaganda techniques before aggregating them, which proved beneficial especially when fine-tuning models on more ambiguous datasets. The study evaluated four language models, finding that Qwen models generally performed best, while Phi-4 14B consistently outperformed GPT-4.1-nano. The findings highlight the importance of fine-tuning for robust propaganda classification and introduce a new dataset for future research. AI
