Evaluating RAG Chunking Strategies for Enterprise Documents: Semantic Chunking Outperforms Fixed-Size

arXiv·low signal

A systematic evaluation of document chunking strategies for RAG systems applied to dense enterprise documents in the oil and gas sector. The study finds that chunking strategy — often overlooked as an implementation detail — is a primary determinant of RAG quality, with semantic chunking methods significantly outperforming fixed-size approaches on complex technical documents. Directly applicable for practitioners building RAG pipelines over enterprise or regulatory content.
