We invite contributions to the research tracks of The Web Conference 2026 (formerly known as WWW).

The Web Conference is the premier conference focused on understanding the current state and the evolution of the Web through the lens of computer science, computational social science, economics, policy, and many other disciplines.

Important Dates
Abstract submission: September 30, 2025
Full paper submission: October 7, 2025
Authors' rebuttal period: November 24th - December 1st
Notification: January 13, 2026
Camera-ready: January 25, 2026
All submission deadlines are end-of-day in Anywhere on Earth (AoE) time zone.

AUTHORS TAKE NOTE: The official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of the conference. The official publication date affects the deadline for any patent filings related to published work.

Submission Guidelines
We will use EasyChair to manage the submissions and reviewing. All listed authors must have an up-to-date EasyChair profile, properly attributed with current and past institutional affiliation and conflict information.

Abstracts and papers can be submitted through the EasyChair link.

Scope
The scope of the conference is the Web and how it has crucially enabled new research and applications. While the Web feeds on and is part of a broader interdisciplinary ecosystem, including technologies such as machine learning, natural language processing, computer vision, and many others, it remains a distinct scholarly field, with its own research methods, tools, and challenges. A typical Web Conference paper should have an explicit focus on at least one of the following:

understanding, evaluating, and improving the Web as a technical infrastructure; including core Web technologies, standards, and platforms
understanding, evaluating, and improving the Web as a socio-economic system;
understanding better the impact of the Web and Web technologies;
democratizing access to Web content and technologies, making it more accessible, fair, inclusive, and accountable to a wide range of audiences

Relevance
Every submission must clearly state how the work is relevant to the Web and to the track in the first page. Submissions that merely use a Web artifact---e.g., a dataset or a Web Application Programmer Interface (API) or a social network---rather than answering a specific Web-related scientific research challenge, are out of scope and will be desk-rejected.

Tracks
Our research interests are organized in the following tracks:

Economics, online markets and human computation Graph Algorithms and Modeling for the Web Responsible Web Search and retrieval-augmented AI Security and privacy Semantics and Knowledge Social networks and social media Systems and infrastructure for Web, mobile and WoT User modeling, personalization and recommendation Web mining and content analysis

Submission Guidelines
Deadlines. The submission deadlines are strict and no extensions, regardless of circumstances, will be allowed. Placeholder/dummy abstracts are forbidden.

Authorship. The ACM has an authorship policy stating who can be considered an author in a submission as well as the use of generative AI tools. Every person named as the author of a paper must have contributed substantially to the work described in the paper and/or to the writing of the paper and must take responsibility for the entire content of a paper.

Maximum authorship. The number of submissions allowed per author is limited to 7 (seven) maximum, cumulatively across the research tracks. If more than 7 papers are submitted with the same person listed as an author, the additional papers submitted after the first 7 by submission ID, will be desk-rejected after the full paper submission deadline.

Authorship changes. The full list of authors, including the ordering, must be finalized at the point of submission. There cannot be any addition, removal, or reordering of authors after the abstract submission deadline. The only changes allowed are the correction of spelling mistakes or new affiliations.

Authorship means accountability for the work. As such, Large Language Models (LLMs) (e.g., ChatGPT) cannot be considered authors. You can use LLMs to rephrase your text, but you are solely responsible for the text in the paper.

Anonymity. The review process will be double-blind. The submitted document should omit any author names, affiliations, or other identifying information. This may include, but is not restricted to acknowledgments, self-citations, references to prior work by the author(s), and so on. Please use the third-person to identify your own prior work. You may explicitly refer in the paper to organizations that provided datasets, hosted experiments, or deployed solutions and tools.

Formatting Requirements. Submissions must be in English, in double-column format, and must adhere to the ACM template and format (also available in Overleaf). Word users may use the Word Interim Template and the recommended setting for LaTeX is:

\documentclass[sigconf, anonymous, review]{acmart}.

Submissions must be a single PDF file: 8 (eight) pages as main paper, with additional pages for references and an optional Appendix (that might contain details on reproducibility, proofs, pseudo-code, etc), up to a maximum of 12 (twelve) pages in total. The first 8 pages should be self-contained, since reviewers are not required to read past that.

Originality and Concurrent Submissions. Submissions must present original work---this means that papers under review at or published/accepted to any peer-reviewed conference / journal with published proceedings cannot be submitted. Submissions that have been previously presented orally, as posters or abstracts-only, or in non-archival venues with no formal proceedings, including workshops or PhD symposia without proceedings, are allowed. Authors may submit anonymized work that is already available as a preprint (e.g., on arXiv or SSRN) without citing it. The ACM has a strict against plagiarism, misrepresentation, and falsification that applies to all publications.

Ethical Use of Data and Informed Consent. Authors are encouraged to include a section on the ethical use of data and/or informed consent of research subjects in their paper, when appropriate. You and your co-authors are subject to all ACM Publications Policies , including ACM's Publications Policy on Research Involving Human Participants and Subjects (posted in 2021). Please ensure all authors are familiar with these policies.

Please consult the regulations of your institution(s) indicating when a review by an Institutional Ethics Review Board (IRB) is needed. If your work has been reviewed by an IRB, please indicate this in the paper, providing approval numbers where appropriate. Failure to comply with the above-mentioned policy on Human Participants and Subjects will lead to a rejection of the paper.

Submissions that do not follow these guidelines or do not view or print properly, will be desk-rejected.

Reviewing Process
Reviewing. Each paper is submitted to one of the tracks listed above. Papers that do not conform to the conference scope or submission guidelines will be desk-rejected by the track chairs.

Rebuttal. Authors will have the chance to provide a response to the reviews during a rebuttal period. After the end of the rebuttal period, reviewers, together with senior PC members and track chairs, will consider the authors' responses to inform acceptance decisions. There will be no interactive rebuttal between authors and reviewers.

Decision. A range of factors including technical merit, originality, potential impact, quality of execution, quality of presentation, related work, reproducibility of results, and ethics, will be used by the ACs and SACs to make a recommendation. The PC Chairs will make the final decisions.

Conflict of Interest (COI) Policy
All authors and reviewers must declare conflicts of interest in EasyChair. You must declare a domain conflict for employment at the same institution or company, regardless of geography/location, currently or in the last 12 months. You must declare a personal conflict when the following associations exist:

candidate for employment at the same institution or company
co-author on book/paper or co-PI on a funded grant/research proposal in the last 24 months
active collaborator
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 Profession

Publication and Presentation Policies
Publication. All accepted papers will be allowed the same maximum page length in the proceedings (12 pages, of which 8 are content pages), which will be published by ACM and will be accessible via the ACM Digital Library. Accepted papers will require a further revision to meet the requirements of the camera-ready format required by ACM. Camera-ready versions of accepted papers can and should include all information to identify authors, and should acknowledge any funding received that directly supported the presented research.

By submitting your article to an ACM Publication, you and your co-authors acknowledge that you are subject to all ACM Publications Policies, including ACM's new Publications Policy on Research Involving Human Participants and Subjects. Alleged violations of this or any ACM Publications Policy will be investigated by ACM and may result in a full retraction of your paper and other potential penalties.
Please ensure that you and your co-authors obtain an ORCID ID so you can complete the publishing process for an 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. 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.
Registration. To be included in the proceedings, every accepted paper must be covered by a distinct conference registration, e.g., two papers require two registrations, even if they have overlapping authors. This registration must be Full Conference (5-day) or Main Conference (3-day) registration, at the standard (non-student) in-person rate, payment of which must be completed by the camera-ready deadline. This registration requirement applies universally, regardless of attendance or presentation mode.

Presentation. Every accepted paper must be presented at the conference. No-show papers may be withdrawn from the proceedings. There will be two forms of presentation:

Oral Presentation. Among the accepted papers, a subset will be selected for oral presentation. Generally we expect oral presentations to be in-person, but may allow a few online presentations by authors with significant travel difficulties.
Poster Presentation. All papers will be asked to produce a poster on-site. An e-copy will appear on Whova.
Reproducibility. Authors are strongly encouraged to make their code and data publicly available after the review process. We are encouraging the (optional) use of the "Artifacts Available" badge in ACM's Digital Library. If you release any code, dataset, or similar artifact to accompany your paper, and host it in a publicly available, archival repository for research artifacts that provides a Document Object Identifier (DOI), you are welcome to apply for this badge. A special subcommittee will check the artifacts of all accepted papers for availability and relatedness to the paper after the acceptance notification.

Important update on ACM's new open access publishing model for 2026 ACM Conferences!
Starting January 1, 2026, ACM will fully transition to Open Access. All ACM publications, including those from ACM-sponsored conferences, will be 100% Open Access. Authors will have two primary options for publishing Open Access articles with ACM: the ACM Open institutional model or by paying Article Processing Charges (APCs). With over 2,700+ institutions already part of ACM Open with more institutions joining from around the world every week, the majority of ACM-sponsored conference papers will not require APCs from authors or conferences (currently, around 75% on average across all ACM-sponsored conferences).

Authors from institutions not participating in ACM Open will need to pay an APC to publish their papers, unless they qualify for a geographic or discretionary financial hardship waiver. To find out whether an APC applies to your article, please consult the list of participating institutions in ACM Open and review the Policy on Geographic APC Waivers and Discounts Policy and the Policy on Discretionary APC Waivers. Keep in mind that discretionary waivers are rare and are granted based on specific criteria set by ACM. Simply sending a message to ACM indicating an inability to pay an APC is typically insufficient justification for such a waiver. Waivers are based on the specific circumstances of the author(s) requesting the waiver. ACM does take seriously into consideration the institutional affiliation of the authors and whether it is a reasonable expectation that their institution should be joining the ACM Open program. This is necessary for the long-term financial sustainability of the ACM Open model.

Understanding that this change could present financial challenges, ACM has approved a temporary subsidy for 2026 to ease the transition and allow more time for institutions to join ACM Open. The subsidy will offer:

$250 APC for ACM/SIG members
$350 for non-members
This represents a 65% discount off the regular APC list prices, funded directly by ACM. Authors are encouraged to help advocate for their institutions to join ACM Open during this transition period. This temporary subsidized pricing will apply to all conferences scheduled for 2026.
