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

[root]

Hey fellow KDD authors and ML researchers!

As we approach the release of the second-round review results for KDD 2025, it's time to gather, share experiences, and support each other: whether you're nervously checking for updates, celebrating a win, or figuring out your next steps.

🧩 What to Discuss Here:

• What scores did you get after Round 1 & rebuttal?
• Did your rebuttal help push your paper toward acceptance?
• Were you assigned to Research or ADS track?
• Are you seeing trends in novelty / technical quality (TQ) scores?
• What are your thoughts on this year's review quality?

---

️ Be cautious with rebuttals

Some authors reported issues with anonymous external code links (e.g., GitHub repos). Even if anonymized, external links in the rebuttal can trigger desk rejection depending on PC interpretation. If you’re unsure, it’s safest to:

• Clearly reference what's already in the submission
• Avoid linking out to anything not explicitly allowed
• Clarify any confusion in the rebuttal without adding new external content

---

Community Polls & Stats

Some have started collecting anonymized data points on scores and acceptance results; it's great to get a sense of where you stand. If you’ve got numbers (e.g., Novelty: 4 3 3 2, TQ: 3 2 3 2), feel free to drop them in the thread and compare notes!

Let’s try to keep this thread constructive and supportive. Every score is a story, and every rejection can be a redirection.

Looking Ahead

Whether you’re aiming to get into camera-ready or preparing a resubmission, this is the perfect moment to share, learn, and connect with others in the same boat.

Feel free to comment below with your situation, ask questions, or just vent — we’re here for it!

Stay strong, and good luck to everyone

KDD reviews are coming out, and most community-shared scores cluster around 2.6 to 3.6 on average. Common patterns are like 333xx, 433xx, or 422xx, showing that many papers are seen as average in novelty and technical quality. Even submissions authors are proud of are mostly getting 3s, with only a few 4s or 5s. The overall vibe: “low scores are normal, let’s just hope for kind reviewers and make the most of rebuttal.”

In short, KDD remains tough, and scores are modest across the board.

A data point:

GNN work, got

Novelty: 3, 2, 2, 3, 2
Technical Quality: 2, 2, 2, 2, 2
Confidence: 3, 4, 3, 4, 4

Need to rebuttal? anyone knows more? 2 weeks challenge ahead!

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:

@magicparrots

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)

[Sylvia]

@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.

[root]

I hereby paste the historical acceptance rate of KDD research tracks

Conference	Long Paper Acceptance Rate
KDD'14	14.6% (151/1036)
KDD'15	19.5% (160/819)
KDD'16	13.7% (142/1115)
KDD'17	17.4% (130/748)
KDD'18	18.4% (181/983) (107 orals and 74 posters)
KDD'19	14.2% (170/1200) (110 orals and 60 posters)
KDD'20	16.9% (216/1279)
KDD'22	15.0% (254/1695)
KDD'23	22.1% (313/1416)
KDD'24	20.0% (411/2046)

Note that KDD'24 accepted 151 ADS track papers from 738 submissions!

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

@river Hi river,

Excuse me, do you know if these scores are the final scores after the rebuttal? Really appreciate it if you could provide more information about this

[Hsi Ping Li]

@Nilesh-Verma Hi Nilesh, I am sure the scores of your paper are higher than those of most authors. Congs. Besides, did your reviewers increase their ratings for your paper in the rebuttal process?

[river]

@Hsi-Ping-Li

This the best effort scores, meaning I take the latest available scores reported in the community. If they are updated by the authors after rebuttal, then I take that, otherwise I would assume the scores did not change.

For the data points with accept/reject outcome, I think all of them are post-rebuttal scores.

[Hsi Ping Li]

@magicparrots

Hi magicparrots!

did the reviewers raise their scores for your paper after the rebuttal process?
I also submitted a paper about GNN, and only one reviewer out of five raised 1 score for my paper

[Hsi Ping Li]

@river Many thanks for your details!
