Beyond Chunking: Discourse-Aware Hierarchical Retrieval for Long Document Question Answering

Researchers present a discourse-aware hierarchical framework that uses rhetorical structure theory (RST) to improve long-document question answering systems. Rather than treating documents as flat sequences, the approach leverages natural discourse structures to enhance retrieval accuracy across multiple languages and document types.

SmartChunk Retrieval: Query-Aware Chunk Compression with Planning for Efficient Document RAG

Researchers have developed SmartChunk retrieval, a query-adaptive framework that improves retrieval-augmented generation (RAG) systems by dynamically adjusting chunk sizes and compression for document question answering. The system uses a planner to predict optimal chunk abstraction levels and a compression module to create efficient embeddings, outperforming existing RAG baselines while reducing costs.
