TopoChunker framework preserves document topology for improved RAG performance

Researchers have introduced TopoChunker, a novel agentic framework designed to improve retrieval-augmented generation (RAG) by preserving the intrinsic topological hierarchies of documents. Unlike traditional methods that linearize text, TopoChunker maps documents to a Structured Intermediate Representation (SIR) to maintain cross-segment dependencies. This framework utilizes a dual-agent architecture, with an Inspector Agent optimizing extraction paths and a Refiner Agent managing topological context, leading to state-of-the-art performance on benchmarks like GutenQA and GovReport.
