Recsys topic selection

RecSys Topic Selection

Use this before writing. RecSys is a single-domain venue: it is strongest when the central claim is about recommendation — ranking objectives, user/item modeling, offline/online evaluation, feedback loops, exposure and fairness, or deployed recommender behavior. Being merely applicable to recommendation is not enough; the contribution has to speak to a recommender audience.

Fit test

• Prefer RecSys when the main claim is a recommendation result: a ranking objective, a user/session model, an evaluation protocol, an off-policy/counterfactual method, a fairness/diversity/exposure result, or a deployed-system insight.
• Route to SIGIR when the core is ad-hoc retrieval, search ranking, or IR evaluation not tied to recommendation.
• Route to KDD when the contribution is a general data-mining or large-scale algorithm and recommendation is just one application.
• Route to WSDM / TheWebConf (WWW) when the emphasis is web-scale search-and-mining or web systems broadly.
• Route to UAI or an ML venue when the contribution is a general learning/probabilistic advance rather than recommender-specific evidence.
• Route to CHI / CSCW when user or community outcomes dominate over the recommendation algorithm.

Fit signal table

Signal in the project	RecSys reading
A ranking/user-modeling idea evaluated with tuned baselines and a leakage-aware split	Core fit — the house genre
Off-policy or counterfactual evaluation of recommendations	Core fit — a RecSys distinctive
A deployed system with production constraints and A/B evidence	Core fit — route to the Industry track
A reproduction/refutation of prior recommender results	Core fit — route to the Reproducibility track
A general retrieval or mining method, recommendation as one demo	Better at SIGIR / KDD / WSDM
A general ML method with a recommender benchmark tacked on	Better at an ML venue

Which RecSys track

• Main long paper: a rounded recommendation contribution with offline (and ideally online) evidence.
• Main short / Past-Present-Future: one focused finding, or a reflective/forward-looking position.
• Reproducibility: repeating, refuting, or re-scoping prior results; a dataset or framework.
• Industry: a deployed system with production constraints and live evidence.
• Resource / Dataset: a community dataset or software resource with build methodology.

Vignette: where an exposure-correction method goes

A project delivers an off-policy ranker with an exposure-corrected estimator and a simulator bridge. RecSys reading: strong fit — a recommendation-specific evaluation advance is exactly what the venue rewards, Main long paper. Strip the recommendation framing and keep only a generic off-policy estimator, and it drifts toward an ML venue; turn it into a reproduction of three published rankers, and the Reproducibility track becomes the right home.

Sharpening moves before committing

• Name the recommendation primitive: the ranking objective, the user/item model, the evaluation protocol, or the deployment claim. If none exists, the RecSys framing does not.
• Confirm the evidence can meet the venue's evaluation bar (tuned baselines, leakage-aware split, reported variance) — decoration-only benchmarks are a quiet fit failure here.
• Topic emphasis and the track lineup drift between cycles (2026 dropped LBR, added R&P Notes); scan the current CFP before final routing.
