Emotion-Wheel-Guided Audio-Referred Text Representation for Multimodal Emotion Recognition in Conversation (2026.acl-long)
Copied to clipboard
| Challenge: | Existing methods for Emotion Recognition in Conversation ignore their distinct communicative roles and information capacities and apply uniform penalties regardless of affective proximity. |
| Approach: | They propose a modality-aware fusion strategy capturing linguistic features from text as the primary source and audio as a complementary component. |
| Outcome: | The proposed method captures linguistic features from text as the primary source and audio as a complementary component and supervised contrastive loss to encode emotional proximity based on Russell’s circumplex model. |

| Challenge: | rapid growth of scientific literature has made manual extraction of structured knowledge increasingly impractical. |
| Approach: | They propose a system for creating datasets from scientific literature that integrates human-AI teaming principles and iterative workflows. |
| Outcome: | The proposed system improves extraction fidelity and facilitates efficient dataset creation. |
