Hybrid Sparse-Dense Retrieval Efficiency Trade-offs in Text-Table QA Systems

This report synthesises findings from 2 peer-reviewed papers addressing the following research question: What is the efficiency trade-off (inference latency vs. retrieval accuracy) when combining sparse and dense retrieval for hybrid text-table QA systems compared to unimodal baselines in the Telco-DPR. 8 claims were extracted from source literature; 7 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 7.6/10. This report is a machine-generated literature synthesis and does not constitute original research.
