Contriever and DPR Retrieval Accuracy on Natural Questions at 2048-Token Context

This report synthesises findings from 14 peer-reviewed papers addressing the following research question: How does the retrieval accuracy of Contriever and DPR encoders compare on the Natural Questions benchmark when the context window size is increased to 2048 tokens. Retrieval-Augmented Generation (RAG) has recently emerged as a method to extend beyond the pre-trained knowledge of Large Language Models by augmenting the original prompt with relevant passages or documents retrieved by an Information Retrieval (IR) system. RAG has become. 5 claims were extracted from source literature; 5 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 8.7/10. This report is a machine-generated literature synthesis and does not constitute original research.
