AB - This study proposes a parameter-efficient emotion recognition model optimized for Korean counseling dialogues to address the demand for online psychological crisis response. Parameter-efficient fine-tuning (PEFT) techniques, specifically LoRA and QLoRA, were applied to KcBERT and evaluated against full fine-tuning and KoGPT2 using the AI Hub(Artificial Intelligence Hub) corpus. Results show that LoRA-based KcBERT achieved 0.824 accuracy and 0.812 F1-score while updating only 0.3% of parameters. t-SNE analysis confirmed stable emotional representation learning. This research demonstrates that high-performance emotion recognition can be practically deployed in resource-constrained environments, significantly improving the efficiency of AI-based mental health support.
