In this paper, we address the challenges of text-based emotion detection, focusing on multi-label classification, emotion intensity prediction, and cross-lingual emotion detection across various languages. We explore the use of advanced machine learning models, particularly transformers, in three tracks: emotion detection, emotion intensity prediction, and cross-lingual emotion detection. Our approach utilizes pre-trained transformer models, such as Gemini, DeBERTa, M-BERT, and M-DistilBERT, combined with techniques like majority voting and average ensemble voting (AEV) to enhance performance. We also incorporate multilingual strategies and prompt engineering to effectively handle the complexities of emotion detection across diverse linguistic and cultural contexts. Our findings demonstrate the success of ensemble methods and multilingual models in improving the accuracy and generalization of emotion detection, particularly for low-resource languages.

In this paper, we detail the IASBS team’s approach and findings from participating in SemEval-2024 Task 10, “Emotion Discovery and Reasoning in Hindi-English Code-mixed Conversations (EDiReF).” This task encompasses three critical subtasks: Emotion Recognition in Conversation (ERC), and Emotion Flip Reasoning (EFR) in both Hindi-English code-mixed and English dialogues. Our methodology integrates advanced NLP and machine learning techniques, focusing on the unique challenges of code-mixing, such as linguistic diversity and shifts in emotional context. By implementing a robust framework that includes data preprocessing, and feature engineering using models like GPT-4 and DistilBERT, we extend our analysis beyond mere emotion identification to explore the triggers behind emotion flips. This endeavor not only achieved third place on the leaderboard, demonstrating a high proficiency in emotion and flip detection with an F1-Score of 0.70 but also significantly contributed to the advancement of emotional AI. Our findings offer valuable insights into the complex interplay of emotions in communication, showcasing the potential for enhancing applications across various domains, from social media analytics to healthcare, and underscore the importance of understanding emotional dynamics in code-mixed conversations for future research and practical applications.
