English(EN) Correct, Cited, and Two Years Out of Date: Measuring Version Leakage in RAG

新基准显示 RAG 系统存在版本泄露问题

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-24 14:30

一项关于检索增强生成（RAG）系统的研究揭示了版本泄露的严重问题，即系统使用过时信息错误地回答问题。该研究开发了一个新的基准，使用了九年的美国联邦采购条例来衡量这个问题。研究结果表明，虽然 RAG 系统可以正确引用信息，但它们常常无法提供与指定日期相关的信息，材料泄露是一个关键问题。 AI

影响突出了 RAG 系统的一个关键缺陷，这可能会影响其在时间敏感信息检索方面的可靠性。

本文如何被排名

Signal score: 26 / 100; Composite score across the factors below. Higher = stronger signal that this story matters right now.
Newsworthiness bucket: Tool; 研究论文，详细介绍了衡量 RAG 系统版本泄露的新基准。[lever_c_demoted from research: ic=1 ai=1.0]
Source corroboration: Single-source cluster; Only one publisher covered this so far. Single-source stories can still rank when the publisher is high-authority, but they lack cross-source corroboration.
Topics: paper, product; Editorial topic classification. Feeds into how the story surfaces on /topic/<slug> hub pages and into the per-entity coverage mix.
AI-industry relevance: High; Clearly on-topic for AI-industry coverage.
Story freshness: Breaking (< 6h); Fresh story with cross-source coverage still developing. Ranking may shift as more sources report.

Correct, Cited, and Two Years Out of Date: Measuring Version Leakage in RAG

I built RAG over nine yearly revisions of federal acquisition regulations and asked it questions "as of" specific dates. Plain RAG answers from the wrong version 80% of the time — fluently, with citations. Date handling fixes it without hurting recall. <a class…
