Beyond Semantic Similarity: Appraisal-Guided Chain-of-Thought Reasoning and Retrieval for Multimodal Emotional Support Conversations (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing retrieval-augmented generation paradigms rely on semantic similarity to retrieve historical dialogues that are surface analogous but therapeutically incongruent. |
| Approach: | They propose to use appraisal-guided reasoning chains to generate appraisal-based reasoning chains and apply a dual-signal verification mechanism to verify and correct them. |
| Outcome: | Extensive experiments on two ESC benchmarks show that the proposed model significantly outperforms state-of-the-art models. |
