The pith

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The reading

Knowledge editing methods are usually scored by whether a model recalls a single updated fact, and on those tests many methods score near perfection. ScEdit argues that this misses how edited knowledge is used in practice: when a user asks a 'How'-type question, the model must fold the new fact into a step-by-step script without contradicting itself. The paper builds a benchmark of script questions paired with counterfactual and temporal edits, and measures editing success both at the token level and on full generated scripts. Across GPT2-XL, GPT-J, and Llama 3, every tested editing method loses ground in the script setting, with the script-based efficacy metric dropping on average 27% relative to the standard paraphrase-success metric. If the paper is right, near-perfect fact-recall scores overstate how ready edited models are to serve as planning assistants.

What carries the argument

The load-bearing object is the cloze-format script prompt $g_{Q_{i,k}}$. For each edit $(s,r,o_c)\mapsto(s,r,o)$, the benchmark generates a 'How' question $Q_{i,k}$, obtains a script that encodes the old object $o_c$, truncates that script at the first appearance of $o_c$, and concatenates the truncated script with the question. Token-level metrics then ask whether the edited model assigns higher probability to $o$ than to $o_c$ under this prompt (S-ES), whether neighboring facts survive in analogous scripts (S-NS), and how much probability mass neighbor objects lose (S-BO). Text-level metrics score the model's full generated scripts on Executability, Coherence, Consistency, and Completeness via 7-point Likert ratings from both GPT-4 and human annotators. The truncation is the mechanism that converts a fact-recall test into a propagation test: the model must continue an existing procedure under the new fact rather than answer a question in isolation.

What would settle it

Run the same edits and models with a from-scratch script-generation prompt (no truncated prefix) and score whether the new object appears and human raters judge the script coherent; if from-scratch success approaches the paraphrase-success level while S-ES stays low, the benchmark's difficulty is driven by the cloze truncation rather than by a genuine failure to propagate edits.

Watch

Extended reading notes

Core claim

The central claim is that script-based evaluation exposes a systematic gap in current knowledge editing: edited models prefer the new object on the bare fact prompt, but often fail to carry that object into a multi-step script, and the scripts they do produce lose coherence, executability, or consistency. ScEdit formalizes this with Script-based Efficacy Success (S-ES), computed by cloze-filling a script that was truncated just before the old object first appeared, and reports an average 27% drop in S-ES relative to the analogous Paraphrase Success metric across all methods and models tested. The paper further reports that token-level efficacy (ES) does not strongly track script-level outcomes, and that text-level coherence correlates only weakly with S-ES, meaning the two evaluation levels capture different kinds of failure. On this evidence, the paper concludes that script scenarios are a harder, more realistic test bed for knowledge editing than fact-recall benchmarks.

Load-bearing premise

The load-bearing premise is that cloze-completing a truncated script written with the old object fairly measures whether a model can produce updated step-by-step guidance; if real users instead ask for a whole script from scratch, the reported 27% drop could overstate practical editing difficulty.

Editorial extensions

If this is right

  • Editing methods that look near-perfect on fact-recall tests should not be assumed ready for agent-style use: every method tested on ScEdit loses ground, and even the strongest token-level performers score only mid-range on text-level coherence.
  • The 27% average drop from paraphrase success to script-based efficacy implies that paraphrased fact questions are not a proxy for procedural generalization.
  • Because S-ES correlates only weakly with text-level coherence and consistency correlates almost not at all with token metrics, rankings of editing methods change when text-level script quality is included.
  • The benchmark makes the edit-locality trade-off explicit: fine-tuning can satisfy the edit but damage script generation, while locality-preserving methods such as MEMIT keep scripts intact but propagate the edit less.
  • ScEdit positions script-based and text-level evaluation as a necessary complement to existing fact-based metrics for future knowledge-editing research.

Reading between the lines

Editorial extensions of the paper, not claims the author makes directly.

  • The cloze setup may be pessimistic relative to real use: users typically ask for a fresh full script, not a continuation of an outdated truncated one, so comparing S-ES with a from-scratch generation test on the same edits would separate propagation failure from completion failure.
  • The single-edit, revert-after-test protocol likely understates real-world difficulty; sequential or massive editing, which the paper leaves to future work, could degrade script-level propagation further.
  • Because scripts are short, deterministic, and auditable, script-level checks could serve as a low-cost screening test before deploying an edited model as a planning assistant.
  • The results point toward editing or post-hoc methods that optimize text-level coherence directly, such as step-level verification that the new fact actually appears in the procedure.

Referee Report

3 major / 5 minor

Summary. The paper introduces ScEdit, a script-based benchmark that extends knowledge editing (KE) evaluation from fact recall ("What"-type questions) to procedural guidance ("How"-type questions). The benchmark is built from CounterFact and WikiFactDiff edits; for each edit, GPT-4 generates script questions and scripts containing the old object, and the scripts are truncated at the old object to form cloze prompts. The paper defines token-level metrics S-ES, S-NS, and S-BO, and text-level metrics (Executability, Coherence, Consistency, Completeness), with automatic GPT-4 scoring and a human evaluation on a 400-sample subset. Experiments cover GPT2-XL, GPT-J, and Llama-3 with FT, FT+L, MEND, ROME, MEMIT, and PROMPT. The central claim is that all KE methods drop substantially on script-based metrics—most prominently a reported 27% average drop in S-ES relative to the PS metric of Meng et al. (2022)—and that text-level evaluation reveals additional difficulties not captured by token-level metrics.

Significance. If its metrics are accepted, ScEdit fills a genuine gap: existing KE benchmarks largely measure single-token factual recall, whereas LLM-as-agent applications require models to use edited facts in multi-step procedural generation. The benchmark construction is transparent, with GPT-4 prompts, filtering criteria, and human validation described in the appendices; the 10% sample validation with 94.5% agreement and the public release of the dataset are concrete strengths. The inclusion of both counterfactual and temporal subtasks and multiple open-weight models is also valuable. However, the headline quantitative claim (the 27% drop) is not verifiable from the reported tables, and the S-ES cloze design has a potential confound between procedural editing and distributional cueing. The paper's significance is therefore conditional on addressing these verification and validity issues.

major comments (3)
  1. [§4.1, Table 2] The sentence in §4.1 stating that S-ES "drops by an average of 27% compared to the original PS" cannot be checked from the paper. Table 2 reports ES, S-ES, S-NS, and S-BO, but no PS values appear, and the experimental protocol for the PS runs (same edits, models, random seeds, and prompts) is not described. The later statement that MEND's S-ES drops by "roughly 53% compared to simpler PS tasks" similarly relies on an unreported number. The paper should add a table of paired PS results computed under the same conditions, or it should remove the percentage comparisons from the abstract and §4.1 and replace them with claims that are directly supported by the reported tables.
  2. [§3.1, Eq. (2)] Equation (2) defines S-ES as the next-token preference for the new object under a prompt formed by concatenating the script question with a GPT-4-generated script that was written using old knowledge and truncated immediately before the old object. Because the truncated script is generated with the old knowledge, its preceding steps can cue the old object (for example, the full script in Table 4 contains "Step 5: Apply for a Schengen visa" and earlier flight-to-Paris steps) or can create an unnatural prompt. A low S-ES may therefore reflect cueing or distribution shift rather than a failure to integrate the edit into procedural planning. I ask for a validation of S-ES against free-form generation after editing—for example, generating the complete script from the question alone and measuring how often the new object is used—or at least an analysis of how many truncated scripts still contain old-knowledge cues, before the 27% drop is presented as evidence about procedural editing.
  3. [§4.2, Table 3 and Table 5] The text-level evaluation supporting the claim that methods "face challenges on text-level metrics" is reported for one model only (LLAMA3-8B on SCEDIT-CF) in Table 3, while Table 5 reports a Krippendorff's alpha of -0.09 for Consistency in the human evaluation. Negative agreement means the Consistency ratings are effectively uninterpretable as a reliable measurement, and the conclusions about consistency (e.g., the discussion of PROMPT in §4.2.1) should be qualified accordingly. Please either report text-level results for more models and settings or temper the generalizations, and present metric-wise human agreement prominently in the main text rather than only in the appendix.
minor comments (5)
  1. [§4.1] The sentence "ROME achieves the best overall results across all models and all metrics" is contradicted by Table 2, where PROMPT has the highest S-ES on SCEDIT-T for GPT-J and FT has higher S-ES on SCEDIT-T for GPT-J as well; this should be rephrased to say that ROME has the best average or best trade-off, not the best on every metric and model.
  2. [§4.3] The sentence "GE 2 is included here" is confusing because GE is not defined in the main text; the footnote defines it via Zhang et al. (2018), but the main text should introduce the notation explicitly before using it.
  3. [Appendix C.2] The main text reports Krippendorff's α = 0.43, while Appendix C.2 reports α = 0.45 for inter-rater agreement; please clarify which quantity each number denotes (human–automatic agreement versus inter-annotator agreement) and use consistent notation.
  4. [Table 2 and throughout] Model names are inconsistent ("GPT2-XL" vs. "GPT-2 XL", "LLAMA3" vs. "Llama 3"), and the table captions should state the exact model sizes (e.g., Llama-3-8B) for reproducibility.
  5. [§4.2.2] The phrase "Spearman's β" is not standard notation; this should be Spearman's rank correlation coefficient ρ or another clearly named coefficient with a reference.

Circularity Check

0 steps flagged · score 1.0 of 10

No significant circularity: ScEdit is a self-contained empirical benchmark; the headline 27% PS comparison is a verification issue, not a circular reduction.

full rationale

ScEdit is an empirical benchmark paper, not a derivation. Its core contributions—the token-level metrics S-ES, S-NS, and S-BO (Eqs. 2–4) and the text-level Likert ratings—are defined and then applied to edited models. No parameter is fitted to make a measured outcome match an input, and no prediction is computed from its own evaluator. The observed performance drops are contingent measurements: for example, FT reaches 71–99% S-ES on different models and GPT2-XL ROME achieves 74.76% on SCEDIT-CF, so S-ES is not forced to be low by construction. The abstract's "27% drop" compares S-ES to the PS metric of Meng et al. (2022), but PS values are not reported in Table 2; this is a replicability and verification concern, not a circularity, because the comparison is an external benchmark rather than an input to the metric. The only self-citation (Wang et al., 2024f, which shares authors Xinye Li and Dianbo Sui) appears in a related-work list and is not load-bearing. The GPT-4 generator/annotator overlap is acknowledged in the Limitations and partially checked by human evaluation (Krippendorff's alpha 0.43, Spearman's beta 0.72), so the text-level findings have independent support. The dataset intentionally filters for Script Questions that "meaningfully hinge on the edited fact," which makes the benchmark challenging by design, but this selection is a benchmark-construction choice rather than a logical circularity. No circular step can be exhibited from the paper's equations or citations, so the honest finding is no significant circularity.

Assumptions & free parameters 0 free parameters · 4 assumptions · 0 invented entities

No numerical parameters are fitted to data. The benchmark relies on the domain assumption that script-based 'How' questions are a meaningful proxy for real-world agent tasks, and that GPT-4-generated scripts and judge scores are valid after filtering. The headlined 27% drop also implicitly assumes that a fair comparison to previously published PS numbers is possible.

assumptions (4)
  • domain assumption Script-based procedural planning tasks are a valid proxy for real-world LLM-as-agent knowledge editing scenarios.
    The paper motivates ScEdit by the rise of LLM agents and assumes 'How' questions exercise knowledge propagation better than 'What' questions. This is stated in Sections 1 and 3.1.
  • domain assumption The S-ES metric, computed by cloze-completing a truncated old-knowledge script, measures script-based editing success.
    Equation (2) defines S-ES; the paper treats it as a generalization of paraphrase success, but the truncation procedure creates an artificial context where the model must override old object tokens. The validity of this proxy is not independently established.
  • domain assumption The comparison between S-ES and the PS metric from Meng et al. (2022) is valid despite differing implementations.
    Section 4.1 reports a 27% average drop relative to the original PS without showing PS values in any table or describing the PS computation setup in this work.
  • domain assumption GPT-4 generated data and GPT-4 judge scores are reliable after manual filtering.
    Sections 3.2 and C.1 rely on GPT-4 for dataset construction and text-level evaluation. The authors acknowledge potential bias in Section 7, and the human evaluation shows only moderate agreement overall.

read the original abstract

Knowledge Editing (KE) has gained increasing attention, yet current KE tasks remain relatively simple. Under current evaluation frameworks, many editing methods achieve exceptionally high scores, sometimes nearing perfection. However, few studies integrate KE into real-world application scenarios (e.g., recent interest in LLM-as-agent). To support our analysis, we introduce a novel script-based benchmark -- ScEdit (Script-based Knowledge Editing Benchmark) -- which encompasses both counterfactual and temporal edits. We integrate token-level and text-level evaluation methods, comprehensively analyzing existing KE techniques. The benchmark extends traditional fact-based ("What"-type question) evaluation to action-based ("How"-type question) evaluation. We observe that all KE methods exhibit a drop in performance on established metrics and face challenges on text-level metrics, indicating a challenging task. Our benchmark is available at https://github.com/asdfo123/ScEdit.
