Chunking strategies for dense retrieval evaluated for effectiveness and cost

A new paper evaluates eight different chunking strategies for dense retrieval systems, considering not only retrieval effectiveness but also operational costs like indexing throughput, query latency, and memory usage. The study found that computationally expensive chunking methods do not consistently outperform simpler ones. The optimal strategy is dependent on factors such as the embedding model, dataset, corpus size, and the specific retrieval metric being optimized. AI

IMPACT Provides insights into optimizing retrieval system performance and operational costs, relevant for developers of large-scale information retrieval systems.

    When Is Complex Chunking Worth It? A Multi-Objective Evaluation of Chunking Methods at Scale

    Dense retrieval is commonly evaluated on benchmarks that represent each document with a single embedding, even though real-world retrieval systems often index long documents that require chunking. In these settings, the chosen chunking method not only affects retrieval quality, b…
