At SIGIR, related work is a credibility exam graded by reviewers who may have written the papers you cite. IR is an old field with a living canon: a related-work section that starts retrieval history at BERT signals a visitor from an adjacent community, which primes every other judgment. This skill builds positioning that demonstrates lineage fluency and states the delta mechanically.
An IR paper is expected to know which research line it extends and to cite the
line's origin plus its current SIGIR-era frontier. The canonical lines and their
anchors (all venue-verified — see ../../resources/exemplars/library.md):
| Line | Origin anchor | What your delta sentence must contrast |
|---|---|---|
| Probabilistic/lexical ranking | Robertson-era BM25 work; Ponte & Croft's language-modeling approach (SIGIR 1998) | Which term-weighting/estimation assumption you change |
| LM smoothing & estimation | Zhai & Lafferty (SIGIR 2001) | Estimation method, prior, or evidence source |
| Graded evaluation | Järvelin & Kekäläinen (SIGIR 2000; nDCG lineage) | Which validity gap your metric/protocol closes |
| Neural re-ranking / late interaction | ColBERT (SIGIR 2020) | Interaction granularity, storage, or supervision |
| Graph collaborative filtering | NGCF (SIGIR 2019), LightGCN (SIGIR 2020) | Propagation structure or training signal |
You do not cite all lines — you identify yours and prove you know both ends of it.
Retrieval's most-cited recent papers are scattered across NLP and ML venues, and misattributing them is a reviewer's one-glance credibility test:
# Bibliography audit: flag entries whose venue field is suspiciously vague
grep -nE "booktitle.*(arXiv|CoRR|preprint)" refs.bib # published since?
grep -nE "@misc|howpublished" refs.bib # citing repos as papers?
grep -in "sigir" refs.bib | wc -l # lineage presence check
For each of the 3-5 nearest neighbors (not the 30 nearest keywords), write one sentence with three fixed slots: what it does (mechanism, not adjective), what we do differently (mechanism again), what that buys (measured, or honestly "which we test in §5"). Neighbors are papers a reviewer would confuse with yours — the correct list usually includes at least one paper from the last two SIGIR volumes, one from a sibling venue (ECIR/CIKM/WSDM/WWW/RecSys), and one journal or TREC-track antecedent that pre-dates the neural era. Missing that third slot is how "novel" claims collide with 2009.
IR moves at preprint speed while SIGIR reviews at conference speed:
sigir-submission).Before freezing the section, simulate the three reads it will get:
Related work earns ~0.75 page in a full paper. Two structures work: after the intro (when positioning is the motivation) or before the conclusion (when the method needs no prior-work vocabulary). In short papers, related work compresses into the introduction as positioning sentences with dense citations — a standalone section is usually a page-budget error.
