LumberChunker: Long-Form Narrative Document Segmentation (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Modern NLP tasks rely on dense retrieval methods to access up-to-date and relevant contextual information. |
| Approach: | They propose a method that leverages an LLM to dynamically segment documents by iterating on a set of sequential passages to identify the point where the content begins to shift. |
| Outcome: | The proposed method outperforms the most competitive baseline by 7.37% in retrieval performance and integrates into a RAG pipeline. |
