KDD Review Process

Use this to model decisions rather than guess at them. KDD review runs on OpenReview, per track and per cycle (the venue groups are literally named by track x cycle, e.g. Research_Track_Cycle_2). Reconfirm the current cycle's mechanics before relying on any stage detail — KDD tunes its process between cycles, not just between years.

Decision machinery

• Reviewers score against the CFP's stated factors: technical merit, originality, potential impact, quality of execution, quality of presentation, related work, reproducibility of results, and ethics.
• Authors respond to each review in the rebuttal window — text only, no hyperlinks.
• Area chairs synthesize reviews, rebuttals, and reviewer discussion into a recommendation.
• PC chairs make final decisions. This last step is real, not ceremonial: calibration across areas happens above the AC.

The three-outcome game

Unlike single-shot venues, KDD's decision space includes Resubmit, and the CFP frames resubmissions that properly address noted concerns as having better odds than fresh submissions. Strategic consequences:

Treat reviews of a Resubmit paper as a contract: the next cycle's AC sees the old forum, so selectively ignoring named concerns is visible and costly.

Who reviews at KDD

The pool mixes academic data-mining researchers with industry practitioners — a KDD-specific blend with predictable reading patterns:

• The academic reader audits novelty against the mining literature and checks whether ablations isolate the claimed mechanism.
• The practitioner reader audits data realism: temporal splits, leakage, baseline tuning symmetry, and whether "deployable" claims survive contact with production constraints.
• A paper that satisfies one reader and insults the other (elegant method on toy splits; solid system with no delta over known methods) lands in the borderline pile where the rebuttal decides.

Review-integrity rules worth knowing as an author

• KDD 2026 forbade reviewers from pasting any passage of a paper under review into generative-AI tools verbatim, and required authors to disclose their own generative-AI use in the submission form. Symmetrically, your rebuttal should not read as unedited model output — ACs increasingly discount it.
• Confidentiality runs both directions; do not cite or publicize reviewer text during the process.

Reading a KDD review packet

Triage order for a 3-4 review packet:
1. Extract every sentence naming a missing experiment, baseline, or
   leakage risk -> these are Resubmit-contract items.
2. Classify each reviewer: academic-lens / practitioner-lens / unclear
   (their objections need different evidence types in rebuttal).
3. Find the AC-visible consensus: an objection raised independently
   twice outweighs any single reviewer's pet issue.
4. Score your realistic ceiling: all-borderline packets are rebuttal-
   winnable; a unanimous soundness objection is a next-cycle project.

Cycle dynamics

• Two cycles a year change the rejection calculus: the distance from a Cycle 1 decision to the Cycle 2 deadline is short, so "fix and resubmit" is a same-year path — plan experiment capacity for it before the decision arrives.
• Per-cycle notification and discussion dates for the current cycle were not publicly verifiable at pack-build time (待核实); pull them from the OpenReview group or CFP timeline before promising a calendar to co-authors.

Leverage per decision factor

The CFP's factor list is long; leverage over it is not uniform. Where author effort converts into recommendation movement:

Stage-by-stage realism

• Bidding/assignment: the registered abstract determines who bids; a misleading abstract buys mismatched experts (kdd-submission).
• Reviews land: score the packet against the ceiling model above before drafting anything; rebuttal energy is finite.
• Discussion: reviewers converge more than they diverge; the rebuttal's job is to arm the sympathetic reviewer with checkable coordinates.
• AC recommendation: written for the PC chairs, so the rebuttal summary line the AC can quote verbatim is the highest-value sentence you write all cycle.
• PC decision: calibration can move borderline cases both directions; nothing an author does at this stage helps, which is why the earlier stages get the effort.

Output format

[Stage] submitted / reviews-in / rebuttal / decision / resubmit-window
[Packet read] R-lenses: <academic/practitioner mix>, consensus objection: <...>
[Realistic ceiling] accept / borderline-rebuttal-decides / resubmit-target
[Resubmit contract] <named concerns that must be addressed if returning>
[Integrity checks] genAI disclosure filed / confidentiality clean
[Next move] <one action with owner>
