This report synthesises findings from 9 peer-reviewed papers addressing the following research question: What is the impact of model size scaling on the inference efficiency and retrieval accuracy of geodesic distance-based dense retrievers versus Euclidean-based models in Dutch IR tasks. 7 claims were extracted from source literature; 7 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 9.2/10. This report is a machine-generated literature synthesis and does not constitute original research.Research goal: What is the impact of model size scaling on the inference efficiency and retrieval accuracy of geodesic distance-based dense retrievers versus Euclidean-based models in Dutch IR tasks?Autonomous literature synthesis.
