SIGIR Author Response

First establish what response channel exists this cycle. SIGIR does not have a famous institutionalized rebuttal ritual the way ICLR or KDD do, and whether a given edition runs an author-response or discussion phase for full/short papers was not verifiable for 2026 (待核实 — check the track page and the OpenReview timeline of your own submission). This skill therefore covers three situations: a real response window, no window at all, and the post-rejection letter.

Situation 1: the cycle offers a response window

Treat it as a precision instrument, not a second paper. SIGIR reviewers are IR methodologists; the objections cluster predictably, and each cluster has a strongest honest answer:

Rules of engagement:

• Answer from the submitted PDF and its cited repository. New experiments are only safe if small, decisive, and clearly labeled as response-phase additions the camera-ready would absorb.
• Quote coordinates ("Table 3, row 4; §5.2 ¶2"), never re-argue the whole section.
• Keep each reviewer's reply self-contained; meta-reviewers read per-review.
• Never break anonymity — no links that reveal a team, no "as we showed at TREC."

Situation 2: no response window

Then the response happens before submission. Write the paper so the predictable objections above are pre-answered: a tuning-protocol paragraph, a significance-testing sentence under every close comparison, an explicit claim-scope sentence for the collection lineup. Budget half a page of the 9 for pre-emption; it is the cheapest acceptance probability you can buy at a venue where you may never get to talk back.

Situation 3: after rejection

• Reviews are a free experiment-design consult from three IR specialists. Extract the demanded evidence into a checklist before feelings archive the folder.
• Route options in the SIGIR family and neighbors: the next SIGIR cycle, SIGIR-AP (which has advertised a revise-and-resubmit route accepting a 1-3 page response letter with a revised previously-rejected paper — verify its current CFP), ECIR, CIKM, WSDM, or a TOIS journal version if the work outgrew conference page budgets.
• If resubmitting to any SIGIR-family venue, keep a diff-log: R2's "missing BEIR evaluation" answered in §5.3 is a sentence in the next cover letter or R&R note.

Drafting discipline

Reply skeleton per reviewer (aim: fits on one screen)
---------------------------------------------------
Thanks + one-line summary of what we changed/clarify.
[W1] <reviewer's words, 1 line>
  -> Answer with coordinates. (Table/§/Fig)
  -> If conceded: what we will do, where it will go.
[W2] ...
Closing: the one thing we most want re-weighed, stated once.

Anti-patterns that reliably backfire with IR reviewers:

• Arguing that nDCG@10 improvements are "obviously meaningful" without a test — this community invented much of the significance-testing-in-IR literature.
• Dumping new tables for every complaint: it signals the submission was premature.
• Answering the meta-question ("is this SIGIR material?") defensively instead of restating the contribution type (ranking model / evaluation method / resource / analysis) and its intended reader.
• Promising camera-ready changes that exceed what the page budget could ever absorb — reviewers do the arithmetic (appendices count inside the budget at SIGIR).

Tone calibration for a small community

IR is a small field: the reviewer you bruise this cycle chairs your session next year. Calibrate register per line, not per document:

Too hot: "R2 clearly has not read Section 5, where this is addressed." Too cold: "We thank the reviewer for this insightful comment and will carefully consider it in future work." Right: "§5.2 ¶3 reports this experiment (Table 4, rows 2-3); we agree the pointer from §3 was too subtle and will add a forward reference."

The pattern: locate, concede the findability problem even when the content exists, and commit to the small fix. Reserve firm disagreement for factual errors, and spend it at most once per reviewer — a response that disputes everything is read as disputing nothing.

Evidence you can compute during a short window

Because run files exist (if sigir-artifact-evaluation was followed), several reviewer requests are answerable in hours without new training:

• A different metric or cutoff on existing runs — minutes with ir_measures.
• A different significance test or correction — minutes on per-topic scores.
• A per-query breakdown by query length/type — an afternoon.
• A new baseline or a new collection — not window material; promise it only if the camera-ready budget can honestly absorb the result either way.

Deciding whether to fight or fold

• Fight when the misunderstanding is factual and the correction has coordinates.
• Fold (and fix) when two or more reviewers independently hit the same evidence gap — at SIGIR that convergence usually means the gap is real.
• A borderline paper with one champion is worth a careful, warm, precise response; a paper whose scores agree at reject is worth a better next submission instead.
