ACL Reproducibility
Use this before an ARR deadline and again at camera-ready. At ACL the
reproducibility instrument is the Responsible NLP checklist: it is
mandatory, reviewers read it alongside the paper, and ARR policy makes
incorrect or misleading checklist content a desk-rejection ground. Treat it as
a claims audit, not paperwork.
The checklist as a claims audit
- Section A: a real Limitations discussion and a risks discussion — reviewers
are told honest limitations must not be penalized, so under-disclosing is
strictly worse than disclosing.
- Section B: every dataset and model you used needs citation, version,
license, and intended-use consistency (see
acl-artifact-evaluation).
- Section C: computational experiments — parameters, budget, infrastructure,
hyperparameter search, and descriptive statistics with error bars.
- Section D: human annotators/participants — instructions, pay, consent,
ethics-board status, demographics where relevant.
- Section E: AI assistants used in research, coding, or writing.
Every "yes" answer should carry a section/appendix pointer; every "N/A" should
survive a hostile reading of the paper.
Reporting floor for the modern NLP paper
| Experiment type |
Minimum disclosure that survives ACL review |
| Fine-tuned models |
Model + version, seeds, LR/schedule, epochs, selection criterion, dev-set use, runs count |
| Prompted LLMs |
Exact prompts, decoding params (temperature, top-p, max tokens), model snapshot date/version, n samples |
| API-based closed models |
Access dates, version string, cost/queries, caching strategy, note on irreproducibility risk |
| Human evaluation |
Instructions, item counts, raters per item, agreement statistic, pay |
| New metrics |
Implementation source, correlation evidence, code in supplement |
Contamination and leakage auditing
- State which evaluation sets could plausibly appear in pretraining corpora
and what you did about it: n-gram overlap scans, canary checks, dataset
release date vs model cutoff reasoning.
- For benchmarks you release, record a creation date and content hash so
future contamination is auditable.
- For claimed generalization, verify the test languages/domains genuinely
weren't leaked through translation or paraphrase of training data.
Variance discipline
- Single-run leaderboard deltas are the classic ACL review complaint. Report
mean and deviation over multiple seeds or prompt paraphrases, and say in the
caption what the interval is.
- When compute makes many runs impossible, say so, quantify what you could
(e.g., variance on the smallest model), and scope claims accordingly —
checklist Section C expects the compute budget stated either way.
Consistency sweep before submission
- Grep the paper for every number that a checklist item claims exists
(error bars, splits, licenses, pay). Missing → fix paper or answer.
- Check the supplement actually contains what Sections B/C reference.
- Confirm Limitations mentions the weaknesses your own experiments exposed;
reviewers notice when the Limitations section dodges the obvious one.
- Re-answer Section E honestly after the final writing pass — late-stage
AI-assisted rewriting counts.
Degrees of reproducibility to declare
turnkey : one script re-scores released outputs / reruns the pipeline
scripted : code + configs released; needs GPUs, keys, or gated data
descriptive: enough prose + prompts that a motivated lab could rebuild it
closed : hinges on private data or deprecated APIs — say so in Limitations
Declare the level you actually achieve. At ACL, releasing model outputs is
the cheap trick that upgrades many LLM papers from descriptive to turnkey,
because re-scoring needs no compute.
Prompt-disclosure block that satisfies reviewers
A reusable appendix pattern for each prompted experiment:
Experiment: Table 3, zero-shot NLI
Model: <name + exact version/snapshot + access date>
Decoding: temperature=0.0, top_p=1.0, max_tokens=16
Prompt (verbatim, incl. whitespace):
"Premise: {premise}\nHypothesis: {hypothesis}\n
Answer entailment, neutral, or contradiction:"
Paraphrases: 5 variants (App. D.2); reported number = mean over variants
Post-processing: first-token match, case-insensitive; ties -> neutral
Failures: non-parseable outputs counted as errors (2.3% of calls)
The last two lines — parsing rules and non-parseable handling — are where
most "we could not reproduce the number" disputes actually originate.
Cheap wins ranked by effort
- Release model outputs alongside code (near-zero cost, enables re-scoring).
- Log and report seeds + run counts in every caption while runs are fresh.
- Pin dataset versions/commits in the bibliography and README now, not at
camera-ready when the version has silently moved.
- Write the compute paragraph (GPUs, hours, total runs incl. failed) the
week the experiments finish.
- Save the exact evaluation-script commit used for headline numbers.
