Call for demonstrations

Invitation and dates

We invite contributions to the Demonstrations Track at the 28th edition of the Web Conference series (formerly known as WWW), to be held May 13-17, 2019 in San Francisco, United States ().

For more than two decades, the Web Conference series has been the premier venue for researchers, academics, businesses and standards bodies to come together and discuss latest updates and the future of the Web. The Demonstrations Track allows researchers and practitioners to demonstrate new systems in a dedicated session. Submissions must be based on an implemented and tested system that pursues one or more innovative ideas in the interest areas of the conference.

Topics include (but are not limited to)

  • Health on the Web
  • Behavioral analysis and personalization
  • Crowdsourcing systems and social media
  • Bio-feedback and emotional computation
  • New human-computer interfaces
  • Internet economics, monetization, and online markets
  • Pervasive Web and mobility
  • Security, privacy, and trust
  • Semantics and knowledge
  • Social networks, social analysis, and computational social science
  • Web infrastructure: datacenters, cloud computing, and systems
  • Web mining and content analysis
  • User modeling, personalization, and experience
  • Mobile, ubiquitous, ambient, and pervasive computation
  • Web science, Web search, and Web systems

Demonstrations are encouraged from academic researchers, from industrial practitioners with prototypes or in-production deployments, as well as from any W3C-related activities. Software (including games or learning platforms) and hardware demos will be considered equally, provided they show innovative use of Web-based techniques. Each submission must make clear which aspects of the system will be demonstrated, and how. They should strive to state the significance of the contribution to Web technology or applications. Submissions will be peer-reviewed by members of the track program committee, who will judge the originality, significance, quality, and clarity of each submission.

Submission Guidelines

Demonstration Track submissions must be formatted according to the ACM SIG Proceedings Template and are limited to four pages. It is the authors’ responsibility to ensure that submissions adhere strictly to the required format. The format cannot be modified with the objective of squeezing in more material. Submissions that do not comply with the formatting guidelines will be rejected without review.

Each demonstration track submission should contain an introduction, brief description, screenshots, value and contribution. Submissions should also indicate how the demonstration will be demonstrated and the hardware requirements (for the organizers).

Submissions must be in PDF and must be made through the EasyChair system (Demonstrations Track):

At least one author of each accepted demonstration paper must register for the conference and attend in person to demonstrate the system during the demonstration sessions.

To better identify the value of demonstrations, as well as to reach out to external audiences, we also encourage authors to submit a pointer to a screencast, using web-accessible platforms such as Vimeo or YouTube. The maximum duration of screencasts is 10 minutes. We also highly encourage any external material related to the demo (e.g., shared code on GitHub).

General guidelines

Formatting and Author Identity

Submissions must adhere to the ACM format published in the ACM guidelines (, selecting the generic “sigconf” sample. Submissions must be in PDF format. The PDF files must have all non-standard fonts embedded. Submissions must be self-contained and in English. Submissions that do not follow these guidelines, or do not view or print properly, may be rejected without review. Authors are responsible for ensuring that submissions adhere strictly to the required format.

PDF files must be double-blind. The submitted document should not include author information and should not include acknowledgements, citations or discussion of related work that would make the authorship apparent. Submissions containing author identifying information are subject to rejection without review. You can enable the double-blind mode in the new ACM format by adding the “anonymous” option (e.g., \documentclass[sigconf, anonymous, review]{acmart}). Note however, that it is acceptable to explicitly refer in the paper to the companies or organizations that provided datasets, hosted experiments or deployed solutions. In other words, instead of stating for instance that an experiment “was conducted on the logs of a major search engine,” the authors should refer to the search engine by name. The reviewers will be informed that doing so does not necessarily imply that the authors are currently affiliated with the mentioned organization.

Originality and Concurrent Submissions

Submissions must present original work. Concurrent submissions are not allowed. Papers that have been published in or accepted to any peer-reviewed journal or conference/workshop with published proceedings may not be submitted. Papers that are currently under review, or will be submitted to other meetings or publications may not be submitted. However, submissions that are available online and/or have been previously presented orally or as posters in venues with no formal proceedings, are allowed. Note that if available online (e.g., via arXiv) and not anonymous, their titles and abstract must be sufficiently different from the submission to The Web Conference 2019 in order to limit the risk that a direct search breaks the double blind reviewing requirement. Additionally, the ACM has a strict policy against plagiarism and self-plagiarism ( All prior work must be appropriately cited.

Publication Policy

The proceedings of The Web Conference are published online through the conference website (which will remain live in perpetuity) without a fee, as well as the ACM Digital Library. Upon the acceptance of a paper, no author change is allowed. For each accepted paper, at least one of the authors needs to register for the conference and present the paper. This is mandatory for including the paper in the proceedings.

Conflict of Interest Policy

There is no author declaration of conflict of interest (COI). Reviewers will be asked to declare a COI when the following associations exist:

  • Employment at the same institution or company
  • Candidate for employment at the same institution or company
  • Received an honorarium or stipend from the institution or company within the past 12 months
  • Co-author on book or paper in the last 24 months
  • Co-principal investigator on grant or research project in the last 24 months
  • Actively working on one or more projects together
  • Family relationship
  • Close personal relationship
  • Graduate advisee/advisor relationship
  • Deep personal animosity

Copyright, Permission and Publication License

The International World Wide Web Conference Committee (IW3C2) shall hold copyright in the proceedings and in the individual articles published in the proceedings and shall grant the public permission to use the licensed material contained in the individual articles of the proceedings under the terms and conditions defined in the Creative Commons Attribution 4.0 international license (CC-BY 4.0).

The proceedings will be published in the Association for Computing Machinery (ACM) Digital Library. IW3C2 will publish, on its Web site, persistent links to the Open Access versions of the articles of the proceedings hosted in the ACM Digital Library. ACM formatted DOIs will be registered via Cross reference by the ACM. The IW3C2 Rights Form consistent with the terms stated above is available. We remind you that this agreement is signed with IW3C2 and not with the ACM. The ACM will be responsible for collecting the signed copyright transfer agreements on behalf of the IW3C2.


Papers that (1) describe experiments with users and/or deployed systems (e.g., websites or apps), or that (2) rely on sensitive user data (e.g., social network information), must follow basic precepts of ethical research and subscribe to community norms. These include: respect for privacy, secure storage of sensitive data, voluntary and informed consent if users are placed at risk, avoiding deceptive practices when not essential, beneficence (maximizing the benefits to an individual or to society while minimizing harm to the individual), risk mitigation, and post-hoc disclosure of audits. When appropriate, authors are encouraged to include a subsection describing these issues. Authors may want to consult the Menlo Report for further information on ethical principles, the Allman/Paxson IMC ‘07 paper for guidance on ethical data sharing, and the Sandvig et al. ‘14 paper on the ethics of algorithm audits.

Note that submitting research for approval by each author’s institutional ethics review body (IRB) may be necessary in some cases, but by itself may not be sufficient. In cases where the program committee has concerns about the ethics of the work in a submission, the program committee will consider the ethical soundness and justification of the submission, just as it does its technical soundness. The program committee takes a broad view of what constitutes an ethical concern, and authors agree to be available at any time during the review process to rapidly respond to queries from the program committee chairs regarding ethical considerations. Authors unsure about topical fit or ethical issues are welcome to contact the program committee chairs.
