KDD 2025 2nd-round Review Results: How Did Your Paper Do?

[Sylvia]

I made a comparison of KDD 2024 vs. KDD 2025 scoring/reviewing system. Here you go!

Scoring Dimensions and Their Scales

Scoring Dimension	KDD 2024	KDD 2025	Change
Relevance	1–4	1–4	No change
Novelty	1–5	1–4	Reduced
Technical Quality	1–5	1–4	Reduced
Presentation Quality	1–5	1–4	Reduced
Reproducibility	1–5	1–4	Reduced
Reviewer Confidence	1–5	1–4	Reduced

Note: The reduction from a 5-point to a 4-point scale compresses the neutral midpoint, encouraging reviewers to take a clearer stance on each dimension.

Review Form Structure Changes

Review Element	KDD 2024	KDD 2025	Change
Paper Summary, Strengths, Weaknesses	Required (Free-form)	Required (Free-form)	No change
Questions for Rebuttal	Optional / General	Required: Numbered, specific	New requirement
Resubmission Flag	Not included	"Resubmission" + "Repeat Reviewer"	New
Ethics Review Flag	Yes / No	Yes / No	No change
LLM Usage Disclosure	Not asked	Mandatory	New

Emphasis in KDD 2025

Rebuttal Process:

• Authors benefit from clearly numbered, targeted reviewer questions.
• Reviewers are expected to provide actionable feedback.

Transparency:

• Reviewers must disclose any use of Large Language Models (LLMs).
• Tracks resubmission history and reviewer continuity.

Reproducibility:

• Still emphasized, with refined grading from "insufficient" to "excellent" support materials.

My reproducibility score hurt a lot because of my source code link does not work any more. I was using LimeWire + ShortURL. Real bad service!

Next time, I will use CSPaper!!

I made a summary of data points from KDD 2025 1st round results:

Novelty Scores	Technical Quality Scores	Confidence Scores	Rebuttal Outcome	Final Decision	Notes

So sorry to hear that — sounds like a solid paper.

For my case,
One reviewer gave two 2s just because they didn’t see the value of improving efficiency or where it would be useful, even though that’s the whole point of many ML contributions. Another reviewer didn’t understand the paper and asked for line-by-line comments on pseudocode. That’s just disheartening.

Also noticed each review response is limited to 2500 characters. Does anyone know if we can reply in multiple stacked comments?

Anyone knows the likelihood of an NLP (LLM agent and its evaluation on many public datasets) work accepted to KDD, either main or applied data science track?

[Nilesh Verma]

what are the chances of acceptance in KDD feb, here is my score

Relevance: 3.5 (based on 4, 3, 4, 3, 4)
Novelty: 3.0 (based on 4, 3, 2, 3, 2)
Technical Quality: 3.0 (based on 3, 3, 3, 3, 3)
Presentation: 2.8 (based on 3, 3, 3, 2, 3)
Reproducibility: 3.0 (based on 3, 3, 3, 3, 3)
Reviewer Confidence: 3.4 (based on 3, 4, 3, 4, 3)

@Nilesh-Verma from what I hear, Novelty and TQ (combined with confidence) are two most important dimension for making the final decision. I think TQ scores are pretty good; Novelty scores are not bad either. If rebuttal can increase one of the "2"s to 3, then the chance of getting an acceptance will be even higher.

I hereby paste the historical acceptance rate of KDD research tracks

The KDD PC just opened the comment phase until Apr 18 (AoE). You can respond to reviewer follow-ups or raise concerns to AC/SAC via the Official Comment button.

️ A few don’ts:

• No URLs — they’ll auto-delete your comment.
• No bypassing rebuttal limits — don’t treat comments as extra rebuttal space.
• Don’t badger reviewers — 1 ping is enough.
• Stay respectful — tone matters.

Good luck everyone
