ACL Supplementary

Use this when splitting an ACL paper between body, appendix, and archive. The governing ARR principle: reviewers are not required to consider material in appendices or supplements, so anything decision-critical that lives only there is effectively invisible.

The ACL page anatomy

[ content pages: 8 long / 4 short ]   <- the reviewed argument lives here
[ Limitations (REQUIRED, unlimited) ] <- after conclusion, outside page count
[ Ethics statement (optional) ]
[ References (unlimited) ]
[ Appendices (unlimited, same PDF) ]  <- optional reading for reviewers
+ separate .tgz/.zip archive          <- software / data supplement

Missing Limitations is a desk-reject condition; treating it as one throwaway sentence is a review-stage penalty even when it passes the gate.

What must not leave the body

• The main results table and the headline comparison.
• Task definition and enough of the method that a reviewer can judge novelty.
• At least a summary of the error analysis, a pointer-only error analysis reads as not having one.
• Human-evaluation design in one paragraph: raters, items, agreement.
• The experimental setup at reproduction-outline level; full grids can go down.

What appendices are good at

• Full prompt texts and few-shot exemplars (reference them per experiment).
• Complete hyperparameter tables and search ranges.
• Per-language / per-dataset breakdowns behind an averaged headline number.
• Annotation guidelines and interface screenshots.
• Extended qualitative examples and additional ablations.
• Proofs or derivations for the occasional formal result.
