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

This work evaluates eight representative chunking strategies across two scalable corpora, three embedding models, and multiple corpus sizes, measuring both retrieval effectiveness and system-level costs and shows that computationally expensive methods rarely provide consistent gains over simpler chunking.

Query Performance Prediction under Corpus Growth in Dense Retrieval

This work extends the QPP paradigm by studying query performance degradation under corpus inflation in dense retrieval systems and proposes simple adaptations to established QPP measures, most notably a top-k vs background Wasserstein distance measure, which yield more consistent associations with degradation and outpe...
