MDKeyChunker: Single-Call LLM Enrichment with Rolling Keys and Key-Based Restructuring for High-Accuracy RAG
Researchers introduce MDKeyChunker, a three-stage pipeline that improves RAG (Retrieval-Augmented Generation) systems by using structure-aware chunking of Markdown documents, single-call LLM enrichment, and semantic key-based restructuring. The system achieves superior retrieval performance with Recall@5=1.000 using BM25 over structural chunks, significantly improving upon traditional fixed-size chunking methods.
