Deep at SemEval-2025 Task 11: A Multi-Stage Approach to Emotion Detection

Dong Shenpo


Abstract
This paper presents a novel text-based emotion detection approach for low-resource languages in SemEval-2025 Task 11. We fine-tuned Google Gemma 2 using tailored data augmentation and Chain-of-Thought prompting. Our method, incorporating supervised fine-tuning and model ensembling, significantly improved multi-label emotion recognition, intensity prediction, and cross-lingual performance. Results show strong performance in diverse low-resource settings. Challenges remain in fine-grained sentiment analysis. Future work will explore advanced data augmentation and knowledge transfer methods. This research demonstrates the potential of large language models for inclusive emotion analysis.
