Overview

AI snapshot

Written from the paper’s full text.

TL;DR

RARR is a model-agnostic research-and-revise system that retrieves web evidence for an LM-generated passage and post-edits unsupported content while preserving the original text. Across factoid QA, reasoning chains, and dialog, RARR improves attribution more robustly than prior edit models and preserves original intent over 90% of the time.

Key findings

  • On PaLM NQ outputs, RARR raises auto-AIS from 45.6 to 54.9 and human AIS from 35.4 to 43.4, with intent preservation 90.0, Levenshtein preservation 89.6, combined preservation 83.1, and F1_AP 57.0.
  • On PaLM SQA outputs, RARR raises auto-AIS from 37.6 to 45.1 and AIS from 24.5 to 31.5, with intent preservation 92.6, Levenshtein 89.9, combined 84.6, and F1_AP 45.9.
  • On LaMDA QReCC outputs, RARR raises auto-AIS from 18.8 to 29.4 and AIS from 13.2 to 28.3, with intent preservation 95.6, Levenshtein 80.2, combined 78.1, and F1_AP 41.5.
  • RARR is the only method reported to perform robustly across all three datasets; EFEC and LaMDA preserve original intent only 6–40% of the time, while RARR preserves intent over 90% of the time. Editing increases attribution by up to 13% absolute while changing only 10–20% of the text.

Methods

  • The paper formalizes Editing for Attribution: given a generated passage x, output a revised passage y plus an attribution report A of evidence snippets. It evaluates attribution with sentence-level AIS and an automated NLI-based auto-AIS, and preservation with human intent preservation, Levenshtein similarity, and their combination.
  • RARR uses few-shot prompting with PaLM 540B: comprehensive question generation, Google Search retrieval (K=5 pages, top J=1 evidence per query), an agreement model to detect disagreement, an edit model to revise only when needed, and selection of at most M=5 evidence snippets for the attribution report.
  • Experiments use 150 development and 150 test passages for each generation-model/source-dataset combination: PaLM and GPT-3 on NQ and SQA, and LaMDA and GPT-3 on QReCC. Baselines include EFEC and LaMDA Research; human evaluation and automated metrics are both reported.

Limitations

  • Stated: attribution and preservation may not deserve equal weight depending on the application; the metrics do not capture all aspects of attribution, such as self-evident sentences, varying assertion scope, directness, or implicatures; preservation metrics do not cover discourse or logical coherence, and heavily flawed inputs may require changes that the metrics penalize.
  • Stated: RARR is not fully general—it is not prepared for poetry or long documents without prompt changes—and it tends to preserve rather than delete claims it cannot attribute, even when those are hallucinations. It is also computationally costly because it prompts a large language model.
  • Evident from the text: the main experiments are based on a single run, though Appendix A reports variance over 3 random runs; the paper also notes that evidence trustworthiness and conflicting evidence are not addressed by the current implementation or evaluation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-29, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-29 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Cited sources are checked with a language model’s help (gpt-6-sol).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
