Researchers have developed systems for SemEval-2026 Task 9, a multilingual polarization detection challenge across 22 languages. One approach fine-tuned Gemma 3 models using Low-Rank Adaptation (LoRA) and augmented data generated by GPT-4o-mini, achieving a mean macro-F1 of 0.811 and ranking second overall. Another method focused on fine-tuning mid-size LLMs with QLoRA and data augmentation techniques like anonymization and homoglyphing to improve robustness. AI
