The WSDM demonstrations track provides a platform for showcasing innovative research prototypes and functional systems. It enables authors to share practical insights, engage with leading researchers, and receive valuable feedback from industry experts and experienced members of the research community. The track offers an opportunity to exchange innovative and practical ideas among researchers and practitioners. Each accepted demonstration will also be documented in the conference proceedings, providing broader and lasting visibility for the work.

We invite demonstration submissions on a broad range of topics related to search and data mining on the Web and the Social Web. Areas of interest include, but are not limited to, the following:

An effective submission should capture the interest of active researchers in Web search, data mining, and the Social Web, and should communicate its significance even to those unable to attend the demonstration session. It should present and exemplify an innovative solution to a current or emerging problem, supported as appropriate by a literature review, task analysis, or case study.

The submission should clearly address the following questions:

• What problem does the system aim to solve, and who is its target audience?
• What approach is used to demonstrate the solution?
• What will the demonstration involve, and what functionality will be shown?
• How does the system compare with existing systems?
• What is the potential technical or commercial impact of the technology, including its anticipated adoption timeline and context?

We invite demonstration submissions that align with the topics listed above. The Demonstrations Program Committee will assess submissions based on the originality of the technical innovations presented, the complexity of creating the system, its potential significance, and its relevance to the WSDM community of researchers and practitioners. For submissions centered on case studies, the evaluation will also consider the significance of the case and its applicability to other similar scenarios.

Authors are invited to submit demonstration papers in English, following ACM formatting guidelines and style requirements. Submissions must be in PDF format and must not exceed 4 pages, including diagrams, appendices, and references. Papers exceeding this limit or incomplete submissions will not be reviewed. Unlike regular WSDM paper submissions, demonstration submissions follow a single-blind review process; authors are not required to anonymize their identities.

Papers must be submitted electronically through [DEMONSTRATION SUBMISSION URL TO BE CONFIRMED] and assigned to the Demo Papers track. At least one author of each accepted submission is required to register for and attend the conference to present their demonstration.

Accepted demonstration papers will be included in the WSDM 2027 proceedings as archival publications. Submissions must therefore be original and must not have been previously published or be under consideration at any other venue with archival proceedings. Authors are strongly encouraged to review ACM's authorship and publication policies before submission.

Submitted manuscripts must adhere to the ACM authorship policy. In particular, (i) each author must be a 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 and its presentation in a publication. The policy also governs the use of generative AI tools in authoring papers.
If an author submits numerous manuscripts to the same conference, it is less likely that the author has materially contributed to all of them. Accordingly, the number of demonstration submissions per author is limited to a maximum of 10. If more than 10 manuscripts are submitted with the same person listed as an author, manuscripts submitted after the initial 10 will be rejected without review.

By submitting an article to an ACM publication, authors acknowledge that they and their co-authors are subject to all ACM Publications Policies , including the ACM's new Publications Policy on Research Involving Human Participants and Subjects. Alleged violations of these policies will be investigated by ACM and may result in full retraction of the paper and other penalties under ACM policy.
All authors must obtain an ORCID ID to complete the publishing process for an accepted paper. ORCID iDs improve author discoverability, attribution, and name normalization.

At least one author of each accepted demonstration paper must register for the conference and present the demonstration in person. WSDM 2027 will be an in-person conference, with no provision for remote presentations. If authors are unable to present their work for any reason, they are expected to arrange for a proxy to present it on their behalf. The organizers reserve the right to remove from the proceedings any paper that is not presented during the conference.

All authors and reviewers must declare conflicts of interest in the conference submission system. A conflict of interest must be declared when any of the following associations exists:

In general, authors, Program Committee members, the organizing committee, and other volunteers are expected to adhere to the ACM Conflict of Interest Policy and the ACM Code of Ethics and Professional Conduct.

Submitted manuscripts that do not meet the length, formatting, or originality requirements, or that 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 SIG venues, as well as escalation to the ACM Committee on Professional Ethics (COPE). Similarly, failure by an author to disclose all conflicts of interest, or review of a paper by a referee with an undisclosed conflict of interest, may lead to comparable penalties.
Authors are encouraged to contact the Demo Chairs with questions regarding originality, dual submission, or the conflict of interest policy.

Starting in 2027, ACM will continue its fully Open Access publishing model. Authors may publish through the ACM Open institutional model or by paying an Article Processing Charge (APC). Authors whose institutions do not participate in ACM Open will need to pay an APC unless they qualify for a financial or discretionary waiver. For calendar year 2027, ACM has announced subsidized APC rates of USD 500 for ACM/SIG members and USD 750 for non-members. Authors should consult the ACM Open information page and current waiver and discount policies for authoritative details.

Submit demonstration papers by [SUBMISSION DEADLINE TO BE CONFIRMED] through [DEMONSTRATION SUBMISSION PORTAL TO BE CONFIRMED], selecting the Demo Papers track. Placeholder titles or abstracts that are not informative, such as "TBD," will be desk-rejected.
