Challenge: Existing methods for ERC lack human-like emotion reasoning and discrimination between similar emotions.
Approach: They propose a multi-dimension curriculum with long CoT fine-tuning to clone human-like emotion reasoning for conversational emotion recognition.
Outcome: The proposed model outperforms existing methods on three widely used datasets and shows that it is more intuitive and more accurate.
