Topics of Interest

To view the full range of subjects accepted by each respective community, please review our comprehensive Topics of Interest page before making your selection.

Submission Tracks & Formats

The two primary submission formats—full papers and talks (formerly called “extended abstracts”)—are intended to accommodate the different norms and requirements across the diverse fields represented in the Collective Intelligence and HCOMP communities. Submissions will be selected for inclusion based on their quality and the fit of their topic with the interests of the CI and HCOMP audiences.

• Full papers (max 6000 words, excluding references) will be assigned to a Program Committee member who will recruit 3 external reviewers and write a meta-review. Accepted full papers will be published in the archival 2026 ACM Collective Intelligence or HCOMP conference proceedings which will be available via the ACM Digital Library. These papers will be assigned individual digital object identifiers (DOIs) as citable publications. For a detailed breakdown of the evaluation rubrics and expectations for papers, please consult our dedicated Review Criteria page.
• Talks (formerly “extended abstracts”) (max 1500 words, excluding references) will receive short reviews by two members of the Program Committee focusing on relevance of, and enthusiasm for, the topic. Extended abstracts for accepted talks will be made available to conference participants on the 2026 CI or HCOMP websites. These abstracts will not be archived in the ACM Digital Library nor assigned individual DOIs.

Journal Partnerships

• CI Journal option: Authors of full paper submissions to the CI track have the option of additional consideration for publication in ACM’s Collective Intelligence Journal (CI Journal Fast Track). Authors who select this option in EasyChair agree to share their submitted paper and reviews with the journal’s editors who will, at their discretion, keep or expand the existing set of reviewers and consider the work for publication in the Journal. This option must be selected at the time of initial submission to the conference. Publication fees for the journal follow the same ACM Open model as conference papers, described below. ​
• TiiS Journal option: Authors of full papers submitted to the HCOMP track may be invited to submit extended versions of their work to be considered for publication in a special issue of the journal ACM Transactions on Interactive Intelligent Systems (TiiS). Authors will be notified of this opportunity after the conference review process is completed. Publication fees for the journal follow the same ACM Open model as conference papers, described below.

Submission Information for Papers and Talks

Attendance and Presentations

Authors of accepted full papers and talks will be invited to give oral presentations at the conference. To ensure your accepted submission will be included in the conference program, at least one author of each accepted submission must register to attend the conference by the early registration deadline. Failure to do so will result in the withdrawal of the submission. In-person attendance is required as remote presentations are only allowed under exceptional circumstances.

In the submission form, authors of full papers and talks may check an option to be automatically considered for a poster or demo presentation if the submission is not accepted for an oral presentation.

Awards

CI and HCOMP 2026 will each recognize one best full paper, one best talk, and one best student work (of either type). Program Committee members will be asked to flag submissions they deem worthy of a recognition. The Program Chairs will form a small committee that will read the nominated submissions, consider the comments in the reviews, and select the winners.

Additionally, CI and HCOMP 2026 will recognize outstanding reviewers. PC members will be asked to flag high-quality reviews from external reviewers and fellow PC members. The Program Chairs will acknowledge these outstanding reviewers at the conference and in the proceedings.

Anonymity

CI and HCOMP 2026 will adopt a double-blind review process for both archival full papers and talks. Authors submitting this submission format must ensure that their submissions are fully anonymized by removing all identifying details, including author names, affiliations, and institutions. Authors should also avoid citing any unpublished work of their own.

Supplemental Materials

Authors are invited, but not required, to include supplemental materials such as executables and data files, images, additional videos, related papers, more detailed explanations, derivations, or results, so that reviewers can reproduce results in the paper. These materials will be viewed only at the reviewers’ discretion, who are only obligated to read the submitted papers.

Double Submission Policy

Full paper submissions to CI and HCOMP 2026 must represent original work. Submissions should not have been previously published and should not be under simultaneous peer-review at any other peer-reviewed archival conference or journal. Papers that have appeared at a conference with published proceedings constitute previously published work. If the paper uses some data, measures, or material from previously-published work, it should also contain significant new results and/or focus on a significantly different research question. Works that have appeared at a workshop, poster/demo session, extended abstract, or any non-archival forum do not constitute previously published work, as long as the paper is an extension of the prior work. Any submissions that fail to meet these double submission requirements will be desk rejected.

Talk submissions can be based on previously-published work, as long as the authors clearly cite the publications on which their submission is based. Extended abstracts for accepted talks will be non-archival and made available via the conference website, giving authors the flexibility to further develop their ideas and submit to other venues in the future.

Preprints Policy

We do not prohibit authors from posting preprints of their work on platforms such as SSRN or arXiv either before or during review by the conference. However, to maintain the integrity of the double-blind peer review, we ask that authors refrain from publicizing the research on social media or discussing it with the press until the review process is complete. CI and HCOMP 2026 will enforce this double-blind review policy, and any submissions that fail to meet these anonymity requirements will be desk rejected.

Policy on Irresponsible Reviews

ACM policies forbid the uploading of author text into an LLM or similar system. Doing so, violates the author’s right to confidentiality and shares intellectual property without consent. Reviewing is a professional responsibility and violations are subject to investigation. In line with other SIGCHI conferences’ (e.g., CHI) and computing conferences’ (e.g., CVPR and KDD) policies on irresponsible reviews, CI and HCOMP 2026 employ the following policy on highly irresponsible reviews.

LLMs are NOT allowed to be used for writing the reviews nor the meta-reviews at any step. You cannot use an LLM to write your review. This is true for any LLM, whether you run it locally or use an API.

This policy includes but is not restricted to:

• You can NOT ask an LLM to write content for you. The review needs to be based on your own judgment.
• You can NOT share substantial content from the paper or your review with an LLM. This means, for example, that you cannot use an LLM to translate a review.
• You CAN use an LLM to check the grammar of your (meta-)review.

It is also expected that reviewers will submit fair and thoughtful reviews on time. Program chairs and PC members will check (meta-)reviews for highly irresponsible reviews. If a review is confirmed as “highly irresponsible,” the papers submitted by the reviewer will be desk rejected per discretion of the program chairs. We might also report this incident and this reviewer to the ACM.

ACM Publication Policies

Full papers will be archived and, therefore, must adhere to ACM’s publication policies. Authors hereby acknowledge that you and your co-authors are subject to all ACM Publications Policies, including the ACM Policy on Authorship and ACM's new Publications Policy on Research Involving Human Participants and Subjects.

Please ensure that you and your co-authors obtain an ORCID ID, so you can complete the publishing process for your accepted paper.

ACM Open

Full papers will be published under ACM Open Access. 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).

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 and $350 for non-members. This temporary subsidized pricing will apply to all conferences scheduled for 2026.
