Author-in-the-Loop Response Generation and Evaluation: Integrating Author Expertise and Intent in Responses to Peer Review
The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
The central discovery is a formulation and an empirical result. Rebuttal generation, the paper argues, should be organized around explicit author input: edits the author plans to make, paragraph context, and strategic choices about response actions and length. The paper constructs Re3Align, the first large-scale dataset of aligned review–response–revision triplets—15,521 triplets from 3,394 papers with 439,798 sentence-level edit annotations—where sentence-level edits between original and revised papers proxy author expertise and intent. Using this, it tests REspGen, a modular generation framework, and REspEval, an evaluation suite spanning input utilization (factual grounding, input coverag
What carries the argument
Re3Align is the central object: a dataset of aligned review–response–revision triplets in which sentence-level edits extracted between paper versions serve as proxies for author expertise and intent, linked to specific reviewer concerns through two-way classifiers and similarity matching. REspGen is the generation framework: configurable author input (edit strings with or without paragraph context, plus optional retrieval of paper paragraphs), itemized response planning with 16 response-action labels, length constraints, and iterative refinement driven by REspEval. REspEval operationalizes the dependent variables—generation factuality precision, input coverage recall, length and plan control
Load-bearing premise
The argument collapses if the extracted revisions do not actually stand in for what the author knew and planned while writing the rebuttal—the paper's own human validation of edit-to-review linking reaches only 0.71 precision on one of its two data sources, so some 'author input' may be text that is lexically similar but not the author's intended response signal.
What would settle it
Collect review–response pairs from a venue where authors record their intended revisions at rebuttal time, before revisions exist, and compare REspGen run with those prospective author inputs against REspGen run with post-hoc extracted edits. If the quality advantage of author input disappears under prospective inputs, the proxy assumption fails.
If this is right
- If rebuttal writing is author-in-the-loop, then review-only generation is an incomplete task formulation; systems that omit author input will miss information only authors have.
- Adding author input—planned revision text—improves targeting, specificity, and convincingness of generated responses across five large language models, often above human baselines.
- Richer input, such as paragraph context and retrieved paper sections, improves factual grounding but lowers coverage of the author's core edits, a dilution effect that response systems must manage.
- Imposing length limits lowers response quality; response-plan control alone preserves quality better; combined multi-attribute control remains difficult, with length as the primary bottleneck.
- Evaluation-guided refinement using REspEval feedback produces significant quality gains, especially for initially weak responses, while largely maintaining controllability.
Where Pith is reading between the lines
- The paper's proxy assumption is the point to stress-test: if post-hoc revisions do not faithfully capture what authors knew at rebuttal time, the reported quality gains may reflect extra relevant text rather than true author intent; a live rebuttal study collecting author input during the actual review process would settle this.
- The controllability–quality trade-off suggests a practical design rule: author-in-the-loop rebuttal assistants should let authors choose how much context to reveal, since richer context can actively hurt focus; an interface that lets authors select individual edits rather than whole paragraphs could preserve grounding without dilution.
- Because REspEval decomposes quality into targeting, specificity, and convincingness plus input-utilization metrics, it enables a new kind of diagnostic for other collaborative writing tasks beyond peer-review rebuttals, such as grant revisions or paper revisions.
- The refinement loop is an instance of generator–evaluator iteration; a natural extension is to make refinement online and interactive, with the author choosing among refinements rather than accepting a single revised draft.

A structured set of objections, weighed in public.
Referee Report
Summary. The paper reformulates author response generation (ARG) as an author-in-the-loop task, where the author's expertise and intent are provided as explicit inputs alongside review comments. It contributes (i) Re3Align, a dataset of review–response–revision triplets with 15,521 aligned instances; (ii) REspGen, a modular generation framework supporting author input, response-plan and length control, and evaluation-guided refinement; and (iii) REspEval, a multi-dimensional evaluation suite with 20+ metrics. Experiments with five LLMs across nine settings report that author input improves quality, richer input improves factual grounding but dilutes focus, controls create quality trade-offs, and refinement yields statistically significant gains. The paper also releases dataset and tools.
Significance. The released dataset and evaluation suite are potentially valuable resources for a neglected task, and the paper is ambitious in formalizing author input, controllability, and evaluation for ARG. The human-validation studies for REspEval (agreement ratings >4.17/5, Krippendorff's α=0.81–0.89) and the fine-grained alignment effort are creditable; the resource release is a concrete contribution. However, the central empirical claim—that author input, as simulated, improves response quality—rests on a proxy that may not capture author intent at response time. The temporal leak in the EMNLP24 experiments and the moderate alignment precision on PeerJ are load-bearing issues that need to be addressed before the author-in-the-loop conclusion can be accepted.
major comments (3)
- [§4.2, §6.1, §6.2.1] Temporal leak in the author-input simulation. §4.2 states that author input is simulated via aligned sentence-level edits [ealign], supplied as an edited-sentence string or with paragraph context. For the EMNLP24 experiments (§6.1), these edits are extracted from the post-rebuttal revised paper, while the generation prompt explicitly says the response is written 'during the rebuttal phase, before submitting any revisions' (Table 11). The model is therefore given the exact final wording that was written after the human response, whereas the human baseline was written before that wording existed. The RQ2 conclusion in §6.2.1 ('all models surpass them in most author-input settings') is thus a comparison between humans without the answer key and models with the answer key. This does not establish that author intent available at response time improves quality. A concrete fix is to re-run the
- [§4.3, §6.2.4, Table 14] Evaluation-guided refinement is scored by the same judge that produces the feedback. §4.3 feeds REspEval's justifications and suggestions back into the generator, and §6.2.4 reports 'statistically significant gains' in Table 14 measured with the same GPT-5-based REspEval scores (§5.4). This creates a potential circularity: the model may be fitting the judge rather than producing genuinely better responses. The human validation in §C.2 was performed on static responses and pairwise comparisons, not on original-vs-refined pairs, so it does not establish that refinement-induced improvements correspond to human-perceived quality. I recommend adding a human pairwise evaluation on a random subset of Setting 6/7 vs. Setting 8/9 outputs, or at least reporting human agreement on win/loss for refinement pairs.
- [§3.3, §1] Proxy validity and alignment precision. The paper's load-bearing premise, stated in §1, is that revisions proxy author expertise and intent at response time. But even perfectly aligned post-hoc edits are not necessarily what the author planned during rebuttal; for EMNLP24 the revised text is temporally future (Major 1). In addition, §3.3 reports human-validated alignment precision of only 0.71 for PeerJ and 0.86 for EMNLP24, with errors caused by aggregation of lexically or semantically similar but irrelevant edits. With 29% false positives in PeerJ, the 'author input' condition contains substantial unrelated text, which may explain quality gains as extra context rather than author intent. I recommend reporting results on a high-precision subset (e.g., edits agreed by both CE and AE components), and ablating by the number of supplied edits to separate 'more text' from 'author intent'.
minor comments (5)
- [Limitations] The Limitations section does not mention the temporal-leak or proxy-validity concerns raised above. A dedicated paragraph acknowledging these threats and the steps taken to mitigate them is needed.
- [§4.1] Length-control simulation uses n+50 where n is the human response length. This is an oracle bound that leaks information about the human response; please discuss this choice and its effect on the controllability-quality trade-off (RQ6).
- [Table 3 / Table 12] Several cells contain '/' without explanation (e.g., lenC/planC in settings where the control is not applied). Please add a table note clarifying that these are not-applicable settings. The green highlighting may also be difficult to distinguish in grayscale.
- [§5.2] The order-fidelity definition OF(m)=LCS(s,s*)/|s| is underspecified regarding ties and unmatched actions at the beginning/end. A brief example would improve clarity.
- [Table 14] The 'eD' column is not defined in the caption or text; please define the edit-distance measure used.
Circularity Check
Author-input experiments supply post-hoc final revision text as 'author input,' and refinement gains are scored by the same GPT-5 judge that issued the feedback; both load-bearing claims are partly self-confirming.

[§4.2 (Input Component Configuration) with §6.2.1 (Why Author Input Matters)]
"We simulate author input through aligned sentence-level edits [ealign], where each edit is supplied as either (i) an edited-sentence string (S), simulating rough revision ideas not yet anchored to a specific location, or (ii) the string with its paragraph context and section title... Together, these results demonstrate that author input is both necessary and effective for ARG, motivating our author-in-the-loop framework."
The 'author input' is not a plan available during rebuttal writing; it is the exact sentence from the revised, accepted paper that was written after the human response. The RQ2 result that author input improves quality is therefore partly an artifact of giving the generator the answer key: the model can quote or paraphrase the final revision, while the human baseline was produced before that text existed. The central author-in-the-loop claim is thus supported by a temporal leak rather than by evidence that author expertise/intent as available at response time is beneficial.

fitted input called prediction
[§4.3 (Evaluation-guided Refinement) + §5.4 (Response Quality Evaluation) + §6.2.4 (Refinement Effectiveness)]
"REspEval then evaluates this draft and returns evaluation metrics, justifications and refinement suggestions... are fed back into REspGen to produce a refined response. ... To address RQ7 ... Table 14 ... shows refinement produces statistically significant gains across all LLMs, settings, and quality metrics, confirming the effectiveness of evaluation-guided refinement."
The refinement loop is closed: the GPT-5-based REspEval generates the justifications and suggestions, the generator is instructed to follow them, and the same GPT-5-based REspEval then scores the refined response. The reported improvements are therefore partly the result of the response conforming to the judge's own stated preferences, not an independent measure of quality. Human validation of REspEval on static responses mitigates but does not remove the circularity, since the validation does not cover the judge-guided refinement loop itself.
full rationale
The paper makes several genuinely independent contributions: Re3Align is a large curated resource with human-validated triplet precision, and REspEval is validated against experienced human annotators (agreement >4.17/5; Krippendorff's alpha 0.81-0.89). These elements give the dataset and evaluation tools real value and prevent a fully circular verdict. However, two load-bearing empirical claims are partially self-confirming. First, the central 'author input improves ARG' result operationalizes author input as the final revised sentences from the accepted paper, which are not available at rebuttal time; supplying them is closer to providing oracle text than to capturing author intent. Second, the 'evaluation-guided refinement improves responses' result uses REspEval both as the source of the feedback and as the metric that measures the improvement, so the loop can inflate gains by fitting the judge. Because the paper's headline conclusions depend on these two demonstrations, the derivation chain is only partially independent of its own inputs. Self-citations to Ruan et al. (2024a,b) for revision analysis and alignment classifiers are real, externally evaluated tools (reported F1/accuracy), so they are not themselves the circular step.

read the original abstract
Author response (rebuttal) writing is a critical stage of scientific peer review that demands substantial author effort. In practice, authors possess domain expertise, author-only information, and response strategies - concrete forms of author expertise and intent - and seek NLP assistance that integrates these signals into author response generation (ARG). Yet this author-in-the-loop paradigm lacks formal NLP formulation and systematic study: no dataset provides fine-grained author signals, existing ARG work lacks author inputs and controls, and no evaluation measures response reflection of author signals and effectiveness in addressing reviewer concerns. To fill these gaps, we introduce (i) Re3Align, the first large-scale dataset of aligned review-response-revision triplets, where revisions proxy author signals; (ii) REspGen, an author-in-the-loop ARG framework supporting flexible author input, multi-attribute control, and evaluation-guided refinement; and (iii) REspEval, a comprehensive evaluation suite with 20+ metrics spanning input utilization, controllability, response quality, and discourse. Experiments with SOTA LLMs demonstrate the benefits of author input and evaluation-guided refinement, the impact of input specificity on response quality, and controllability-quality trade-offs. We release our dataset, generation and evaluation tools.
