AIMA at SemEval-2024 Task 10: History-Based Emotion Recognition in Hindi-English Code-Mixed Conversations
This work addresses emotion recognition in Hindi-English code-mixed (Hinglish) dialogues. We propose a history-aware multimodal framework comprising two key components: (1) a Hinglish-to-English translation pre-processing pipeline for linguistic normalization, and (2) a joint contextual modeling architecture integrating bidirectional LSTM or Transformer-based context encoders with an ensemble of multilingual pretrained language models (BERT, RoBERTa, XLM-R). Crucially, we introduce the novel concept of “history-aware contextual modeling”, synergistically coupled with code-mixed translation pre-processing. This design enhances cross-lingual robustness—particularly critical in low-resource emotion recognition in conversations (ERC). Evaluated on SemEval-2024 Task 10 Subtask 1, our approach outperforms all baseline systems, demonstrating the efficacy of jointly leveraging contextual awareness and language normalization for code-mixed emotion classification.
