Sigir Review Process

SIGIR Review Process

SIGIR review is track-partitioned: each track (full, short, resources, reproducibility, perspectives, industry, ...) runs its own OpenReview group with its own reviewer pool, anonymity regime, and calendar. Advice that treats "SIGIR review" as one process misroutes authors. This skill models the machinery and the reviewer psychology; exact per-cycle mechanics (rebuttal windows, score scales, meta-review forms) were not publicly verifiable for 2026 and must be read off your own submission's OpenReview timeline (待核实).

The machinery

The PC-nomination duty has a strategic edge authors miss: your nominated author will review other SIGIR submissions during your own paper's review window. Nominate someone senior enough to review credibly — chairs notice teams that nominate their most junior author, and review quality is a community reputation signal.

What SIGIR reviewers actually score

Across editions, IR reviewing culture weighs evaluation validity above almost everything. The informal reviewer checklist, reverse-engineered from the field's own methodology literature:

1. Is the comparison fair? (Tuned baselines, same collections, same qrels, same metric implementations.)
2. Are the differences real? (Paired significance tests, multiple-comparison handling, variance across seeds for neural systems.)
3. Is the metric-task pairing sound? (nDCG@10 for ad-hoc ranking, recall for first-stage retrieval, judged@k when pools are shallow.)
4. Does the mechanism explain the gain? (Ablations that isolate the claimed source.)
5. Only then: how novel is the idea, and how broadly does it matter?

The consequence: at SIGIR a modest idea with airtight evaluation routinely outscores a bold idea with a shaky one. Papers written novelty-first, evidence-second read as misrouted ML-venue submissions.

Reviewer archetypes and what convinces each

• The evaluation methodologist: reads §Experiments first; convinced by protocol symmetry and correct statistics; enraged by copied baseline numbers.
• The systems pragmatist: asks what it costs; convinced by latency/index-size tables; suspicious of quality wins that ignore efficiency entirely.
• The task veteran: knows the collection's quirks and every prior result on it; convinced by correct positioning against the collection's known ceiling effects.
• The user-focused skeptic: asks whether the offline gain would survive contact with users; softened by honest scope statements about offline evaluation limits.

A submission cannot satisfy all four maximally in 9 pages; it must avoid offending any of them (the four standing objections: unfair tuning, no significance testing, metric mismatch, unexplained mechanism).

Reading a decision packet

Decision-packet triage
----------------------
1. Sort claims-about-your-paper into: factual error / evidence gap / scope dispute.
2. Factual errors -> correction with coordinates (if a channel exists; see
   sigir-author-response).
3. Evidence gaps named by >=2 reviewers -> real; plan the experiment, not the reply.
4. Scope disputes ("should have tested on X") -> decide if X is load-bearing for
   the claim as written; narrow the claim or add X, never argue taste.
5. Extract every "the authors should ..." into the next-version checklist verbatim.

Reading scores like a chair

Without the cycle's exact scale (待核实), read shapes rather than numbers:

• Converging middling scores with the same named gap = a real, fixable defect; the packet is a work order.
• High variance (one champion, one detractor) = the paper's framing lets two archetypes read different papers; the fix is usually §1, not §5.
• Uniform low confidence = the submission landed outside the track's reviewer pool; re-read sigir-topic-selection before blaming reviewers.
• A long, detailed negative review is the most valuable object in the packet — it is the only reviewer who fully engaged; answer it with matching precision.

Confidentiality and conduct

• Submissions are confidential under the ACM Peer Review Policy: reviewers must not share, reuse, or feed submissions to external services; authors likewise must not publicize reviewer text out of context.
• Attempting to identify reviewers, or contacting suspected reviewers about a live submission, is a conduct violation with career-scale downside in a community this small — every senior IR researcher reviews for SIGIR eventually.
• Suspected review misconduct (plagiarized review, LLM-generated boilerplate, conflict violations) goes to the track chairs through official channels only.

After the decision

• Accept: conditional items (if any) become the first camera-ready tasks; see sigir-camera-ready.
• Reject: the packet is a specification for the next venue; the SIGIR-family calendar (next SIGIR, SIGIR-AP, ECIR, CIKM, WSDM) means a well-revised paper waits months, not a year — see sigir-workflow for the routing calendar.
