DTCRS: Dynamic Tree Construction for Recursive Summarization (2025.acl-long)
Copied to clipboard
| Challenge: | Recursive summarization (RAG) is an important method for mitigating large model hallucinations and enhancing answer interpretability. |
| Approach: | They propose a method that dynamically generates summary trees based on document structure and query semantics. |
| Outcome: | The proposed method significantly reduces summary tree construction time and achieves substantial improvements across three QA tasks. |
