Call for Demonstrations

Submitted manuscripts must adhere to the ACM authorship policy. In particular, (i) each author must be the creator or originator of an idea in the work; (ii) each author must make substantial contributions to the work; and (iii) each author must be accountable for the work that was done and its presentation in a publication. The policy was recently updated to govern the use of generative AI tools in authoring papers.

If an author submits numerous manuscripts to the same conference, it is less likely that one has materially contributed to all such submissions. To this end, we limit the number of submissions per author to 10 maximum. If more than 10 manuscripts are submitted with the same person listed as an author, the additional manuscripts submitted after the initial 10 will be rejected without review.

By submitting your article to an ACM Publication, you are hereby acknowledging that you and your co-authors are subject to all ACM Publications Policies, including ACM’s new Publications Policy on Research Involving Human Participants and Subjects. Alleged violations of this policy or any ACM Publications Policy will be investigated by ACM and may result in a full retraction of your paper, in addition to other potential penalties, as per ACM Publications Policy.

Please ensure that you and your co-authors obtain an ORCID ID, so you can complete the publishing process for your accepted paper. ACM has been involved in ORCID from the start and we have recently made a commitment to collect ORCID IDs from all of our published authors. ORCID IDs are required for all authors. We are committed to improve author discoverability, ensure proper attribution and contribute to ongoing community efforts around name normalization; your ORCID ID will help in these efforts.

At least one author of each accepted demo paper must register for the conference (either 3-day or 5-day) to present the paper at the conference in person. Each paper must be accompanied by a paper presentation fee. If you are an author presenting more than one paper, you should pay a paper presentation fee for each accepted paper, but only one conference registration (either 3-Day or 5-Day). WSDM 2026 will be an in-person conference, with no provisions for remote presentations. If authors are unable to present their work for any reason, they are expected to find a proxy to present the work on their behalf. The organizers reserve the right to remove any paper that is not presented during the conference from the proceedings.

All authors and reviewers must declare conflicts of interest in EasyChair. You must declare a reviewer/author as a conflict of interest when the following associations exist:

• employment at the same institution or company, regardless of geography/location, currently or in the last 12 months
• candidate for employment at the same institution or company
• received an honorarium, stipend, or grant from the institution or company within the last 12 months (except where of a modest nature, such as reimbursement of seminar expenses, honorarium for examination of a thesis, and so on).
• co-author on book or paper in the last 24 months
• co-principal investigator on a funded grant or research proposal in the last 24 months
• actively working on any project together
• family relationship or close personal relationship
• graduate advisee/advisor relationship, regardless of time elapsed since graduation
• deep personal animosity

In general, we expect authors, PC, the organizing committee, and other volunteers to adhere to ACM’s Conflict of Interest Policy as well as the ACM’s Code of Ethics and Professional Conduct.

Submitted manuscripts that do not meet the length, formatting or originality requirements, or are concurrently submitted to two venues (including manuscripts with significant overlap), are subject to desk rejection without review. At the discretion of the Demo Chairs and the Steering Committee, egregious violations (including plagiarism) may lead to additional penalties such as a temporary or permanent ban from the venue and sponsoring SIGs venues, as well as an escalation to the ACM Committee on Professional Ethics (COPE). Likewise, failure of an author to disclose all COIs, or cases of a referee providing a review on a paper for which they have an undisclosed COI, may lead to similar penalties. You are encouraged to contact the PC Chairs if you have questions as to the originality conditions, dual submission, or conflict of interest policy.
