The WSDM'27 organizing committee invites proposals for full-day or half-day workshops to be held at the WSDM conference on February 19, 2027. The topics of the proposed workshops should be aligned with those outlined in the call for papers of the main conference. Accepted workshop papers will be published in the Companion Proceedings Volume.

WSDM workshops provide a venue for exploring and discussing emerging research directions and applications. The format and content of each workshop will be determined by its organizers. The tasks of the workshop organizers are as follows:

• Determine the submission deadline for the workshop (if applicable).
• Handle the whole reviewing process, including recruiting the Program Committee.
• Prepare a workshop website featuring the final program and proceedings.
• Publicize the workshop in the relevant communities.
• Prepare workshop notes to be distributed (possibly online) to attendees.
• Submit a workshop summary paper as part of the proceedings.
• At least one organizer must register and attend the workshop in person and supervise the workshop operations.
• Plan for in-person experience (NOTE: there will be no provisions for remote presentations; accepted papers that cannot be presented in-person will be excluded from the Companion Proceedings Volume).

Workshop proposals, in no more than 5 pages (ACM formatting, sigconf style, submitted as PDF), should include the following information and sections:

• Proposed workshop organizers (names, affiliations, and email addresses; identify one person as the primary contact person).
• Short biographical sketch for each organizer, describing relevant experience and qualifications (e.g., previous workshop organizing).
• Description of the workshop: objectives, goals, relevance to WSDM, and expected outcomes.
• Rationale for holding such a workshop during WSDM. Description of the target audience and the estimated number of participants.
• List related workshops in recent Web-related conferences, indicating the differences between the past and the proposed workshop.
• Describe how the organizers intend to encourage physical attendance and in-person activities.
• Proposed workshop duration (full day or half day), format, activities, and schedule.
• NOTE: If this is a recurring workshop (at WSDM or related conferences such as WWW, SIGIR, and KDD), the organizers should highlight the fact and describe past attendance and outcomes.

After workshop acceptance, the organizers will be asked to submit a 2-page summary for inclusion in the conference proceedings.

This year, the WSDM organization will publish a Companion Proceedings Volume that includes the workshop papers. Nevertheless, workshop organizers retain the freedom to opt out of the Companion Volume and arrange an independent publication volume, such as a special issue in a journal.

Workshop proposals can be submitted via Microsoft CMT, choosing the "Others - Workshops" track: https://cmt3.research.microsoft.com/WSDM2027.
