WSDM Topic Selection

Decide if a project is WSDM-shaped before anyone formats a page. WSDM

(pronounced "wisdom") is deliberately narrow: search and data mining **on the

Web and the Social Web**, run as a small, highly selective, traditionally

single-track winter meeting jointly sponsored by four ACM SIGs (SIGIR, SIGKDD,

SIGMOD, SIGWEB). The sponsorship list is the scope diagram - the venue lives at

the intersection of retrieval, mining, data management, and the web itself.

The two-gate test

Gate 1 - the data gate. Is the primary object of study web or social-web

data: queries and clicks, documents and links, user-item interactions, social

graphs, ads, reviews, conversational sessions? A method paper whose experiments

merely include a web dataset fails this gate; the web data must be what the

contribution is about. Tabular-ML, vision, and generic NLP work fail here

regardless of quality.

Gate 2 - the "practical yet principled" gate. The series describes its

emphasis as practical yet principled approaches, and the PC enforces both

adjectives:

• Practical: plausible at platform scale, aware of serving cost, evaluated on

realistic interaction data.

• Principled: a nameable mechanism, bias-aware evaluation, and an explanation

of why it works - not a leaderboard delta.

Projects strong on one adjective route elsewhere: principled-only theory

toward theory-friendly venues, practical-only system reports toward industry

tracks or applied venues.

Scope coverage check (2026 CFP areas)

The 2026 call organized scope roughly as: web search (including query

analysis, evaluation, user behavior and log analysis, and explicitly "Search

with Foundation Models"); web mining and content analysis (including

recommender systems, crawling/indexing); social networks (link prediction,

community detection, computational social science, influence, trust); fairness,

accountability, and explainability for ranking, recommendation, and ads; and

conversational search and assistants. If the project needs a paragraph of

throat-clearing to sound like one of these, note that as a fit warning.

Routing table

| Signal in your project | Better first target | Why |

|---|---|---|

| Core IR theory, test-collection evaluation, no web-mining angle | SIGIR | Deeper IR-methods bench |

| General-purpose mining/ML method, web data incidental | KDD | Scope is data mining at large |

| Web systems, standards, platform measurement, web economics | TheWebConf (WWW) | Broader web-as-artifact scope |

| Solid applied IR/DB/mining result, breadth over selectivity | CIKM | Larger, broader program |

| Recommender-systems contribution with user-centric evaluation | RecSys | Dedicated community and review lens |

| Social-media phenomena, computational social science first | ICWSM | Social-science evaluation standards |

| Learning theory / new architecture, evaluation on static benchmarks | NeurIPS/ICML/ICLR | Method-first review culture |

| Web search/mining/rec with logs, bias-awareness, deployment realism | WSDM | This is the lane |

Tie-breakers when two venues survive: (1) whose recent proceedings contain the

papers you must cite - submit to the ongoing conversation; (2) whose review

process suits the work - WSDM's no-rebuttal, one-in-six regime punishes papers

that need explaining; (3) calendar position (wsdm-workflow maps the chain).

Selectivity realism

Anchor numbers: WSDM 2025 accepted just over 100 of more than 600 submissions

(~16-17%). Single-track capacity keeps the program small by design. Honest

self-assessment questions before committing the August slot:

1. Name the WSDM lineage this joins (see wsdm-related-work).       [____]
2. State the behavioral fact the paper exploits or corrects.       [____]
3. State the mechanism in one clause, no "framework" words.        [____]
4. Which quadrant of evidence is weakest (wsdm-experiments)?       [____]
5. Would the industry half of the PC call the setting realistic?   [____]
6. Is there a reason to *choose* this paper, not just no flaw?     [____]

Blank boxes at question 1-3 usually mean the project is a neighbor-venue paper

wearing WSDM formatting. A weak answer at 6 with strong answers elsewhere

suggests the short-paper track (since 2026) over the long track.

Routing vignettes (fictional)

• *A contrastive-learning objective evaluated on MovieLens and two vision

benchmarks.* Fails Gate 1 - web data is a test case, not the object. Route

to the ML flagships; return to WSDM only if a version emerges whose claims

are about interaction data specifically.

• *A measurement study of coordinated inauthentic amplification on a

microblog platform, with a detection heuristic.* Passes Gate 1; Gate 2

depends on the mechanism. If detection is principled and evaluated for

ranking/mining impact, WSDM fits; if the contribution is the social

phenomenon itself, ICWSM's review culture will value it higher.

• *An LLM-based relevance judge replacing crowd labels, validated against

human judgments on public query sets.* Passes both gates via the

evaluation lineage; equally at home at SIGIR - apply tie-breaker (1):

wherever the papers it must cite appeared last two years.

• A vector-database sharding scheme with a web-corpus benchmark. The

contribution is data management; the web corpus is incidental. VLDB-family

first, WSDM only with a retrieval-behavior angle.

Foundation-model-era fit

LLM work is in scope only through the web lens - the 2026 CFP names "Search

with Foundation Models" and the 2026 Industry Day theme was LLMs and agentic

AI in industrial settings. The test: does the contribution concern how

foundation models *interact with web-scale search, recommendation, or user

behavior* (retrieval-augmentation for search, LLM-based ranking or judgment,

agentic browsing, synthetic-content effects on ranking ecosystems)? A prompt

technique evaluated on static QA benchmarks fails Gate 1 regardless of the

word "search" in its title.
