Topics of Interest

 

Human-AI Complementarity and Alignment (HCOMP)

ACM HCOMP is the premier venue for disseminating the latest research findings on human-AI complementarity and alignment. Our community studies and designs systems that combine the complementary strengths of human and artificial intelligence to achieve outcomes neither could achieve alone, in ways that are ethical, safe, and intentional. This research builds on a foundation established by the HCOMP community during its first decade as an AAAI conference series focused on human computation and crowdsourcing.

HCOMP focuses on the emerging science and practice of human-AI complementarity and alignment. As AI systems become increasingly capable, the field is expanding from studying how humans contribute to building these systems to also studying how humans and AI systems work together as complementary partners. This broader perspective situates complementarity and alignment across the full lifecycle of AI systems, from how systems are built and evaluated to how they are used and governed in practice, with attention to how responsibilities are divided, how collaboration evolves over time, and how alignment is achieved and maintained in real-world use.

While artificial intelligence (AI) and human-computer interaction (HCI) represent traditional mainstays of the conference, HCOMP believes strongly in fostering and promoting broad, interdisciplinary research. Our field is particularly unique in the diversity of disciplines it draws upon and contributes to, including human-centered qualitative studies, HCI design, social computing, machine learning, natural language processing, the broader realms of artificial intelligence (including LLMs and generative AI), economics, computational social science, digital humanities, policy, and ethics. We promote the exchange of advances in human-AI complementarity and alignment not only among researchers but also engineers and practitioners, to encourage dialogue across disciplines and communities of practice.

Example topics for HCOMP include, but are not limited to, the following:

Research on human-AI complementarity

Research on human-centered alignment

Research on human contributions to AI systems

Collective Intelligence (CI)

ACM Collective Intelligence is the premier venue for disseminating the latest research that advances the theoretical and empirical understanding of collective performance in diverse systems, whether biological, technological, or a combination. We are interested in research on a broad range of systems that vary in scale and scope and focus on implications for a diverse range of social, ecological, and economic outcomes.

CI has a transdisciplinary focus devoted to advancing the theoretical and empirical understanding of collective intelligence, broadly designed. The community does basic science on emergent collective phenomena, as well as designing and engineering systems for combining computational and human intelligence. We are interested in research on a broad range of phenomena that vary in scale and scope with implications for a diverse range of social, ecological, and economic outcomes.

Researchers who participate in the CI conference represent a wide and growing cross-section of social science and computer science as well the natural sciences, arts, and humanities. All types of contributions—empirical, conceptual, theoretical, quantitative, and qualitative—are welcome, including computational models.

Topics include (but are not limited to) research that helps us to explain the mechanisms of emergent behavior as well as presentations of design solutions and systems engineering.

Research on collective behaviors including, but not limited to:

Research into systems and tasks to support the following, but not limited to:

Call for Papers and Talks

 

Important Dates

Submission Options

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 HCOMP and Collective Intelligence communities. Submissions will be selected for inclusion based on their quality and the fit of their topic with the interests of the HCOMP and CI audiences. The key differences between formats (see below) relate to the amount of feedback authors will receive and opportunities for inclusion in archival conference proceedings.

Selecting HCOMP or CI Track

When submitting a full paper or talk, authors will be required to select either the HCOMP or CI track, based on the Topics of Interest listed above. Their track selection will determine which Program Committee (PC) reviews their submission. Additionally, for accepted full papers, the track selection will determine the proceedings (HCOMP or CI) in which the paper will be published. In rare cases, the Program Chairs may request permission from the authors to move a submission to a different track if it appears to be a better topical fit.

The submission options can be summarized in the following table:

Submission Option Track Max word count (excluding references) Archival? Review process Where published
Full papers Authors select HCOMP or CI track 6000 Yes; must be original research not previously published 1 PC member coordinates 3 detailed external reviews HCOMP or CI proceedings in ACM Digital Library w/ DOI
Talks (formerly “extended abstracts”) Authors select HCOMP or CI track 1500 No; may be based on cited prior publications 2 PC members provide brief reviews PDF on conference website only (no DOI)

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

HCOMP and CI 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, HCOMP and CI 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

HCOMP and CI 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 HCOMP and CI 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. Extensions might include new results, more in-depth analysis, an evaluation that was not part of the workshop paper, or further experiments. 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.

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. 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. We are committed to improving author discoverability, ensuring proper attribution and contributing to ongoing community efforts around name normalization; your ORCID ID will help in these efforts.

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). With over 1,800 institutions already part of ACM Open, the majority of ACM-sponsored conference papers will not require APCs from authors or conferences (currently, around 70-75%).

To be included in ACM Open, the corresponding author must be affiliated with a participating institution. For APC-eligible articles (research, short paper, and survey) where none of the authors are currently from participating institutions, an APC will be required. Corresponding authors from institutions not participating in ACM Open will need to pay an APC to publish their papers, unless they qualify for a financial or discretionary waiver. To find out whether an APC applies to your article, please consult the list of participating institutions in ACM Open and review the APC Waivers and Discounts Policy. Keep in mind that waivers are rare and are granted based on specific criteria set by ACM.

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:

This represents a 65% discount, 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.

Note: ACM is not lowering APCs, but is instead contributing funds to temporarily subsidize APC pricing as the community adjusts to the Open Access program.

Call for Posters and Demos

 

Authors with emerging and late-breaking work are invited to submit a short (<2 page) writeup to our Posters track. We encourage recent findings, innovative ideas, and early proof-of-concepts that will spark productive conversations within our dynamic and interdisciplinary community. Projects involving hands-on demonstrations of an interactive system, tool, or technology are encouraged to submit to the Demos track. Demos track require a walkthrough video in addition to a brief writeup.

When submitting your Poster or Demo, you will be asked to indicate whether your project is more strongly affiliated with collective intelligence (CI) or human-AI complementarity and alignment (HCOMP) topics. Please see the ‘Topics of Interest’ section for details on the research topics most closely associated with each one.

Important Dates

Demos

Demos offer a high-visibility, hands-on opportunity to present interactive systems, tools, or technologies related to collective intelligence, collaborative human-AI systems, and human-centered AI. This track provides a platform to showcase prototypes, systems, exhibits, or installations that engage participants through live interaction. If you’ve built something exciting, this is your chance to show it in action! Demo submissions should include a video walkthrough of the system, along with a 1-2 page description of the system, the nature of interaction with users, and the expected form of audience engagement. Accepted demos will be presented in-person at the conference. CI/HCOMP will provide presenters with a table, 2 chairs, a power outlet, and wi-fi; if additional materials are required, they must be requested by contacting the Posters/Demos Co-Chairs directly and they may not be guaranteed.

Posters

Posters present concise reports of recent findings or innovative work relevant to collective intelligence (CI) and human-AI complementarity and alignment (HCOMP). Poster submissions are perfect for work that is still in progress or has not yet reached the completion level required for full paper submission. Each poster submission should offer some contribution to the CI or HCOMP research community, whether in results or in potential. Accepted posters will be presented in-person at the conference in the form of a poster session, offering authors the chance to engage with attendees and receive feedback in an interactive format.

Submission Details

CI/HCOMP takes pride in our interdisciplinary community. We welcome work from a variety of perspectives and backgrounds, and we look forward to reading your contributions. If you have any questions in the meantime, please reach out to the Posters/Demos Co-Chairs:

Call for Workshops

 

Overview

We invite proposals for workshops at HCOMP 2026 and CI 2026. Workshops are a gathering place for researchers, practitioners, and industry professionals to bring together communities with common research interests and agendas, discuss ongoing work, and initiate new collaborations.

Workshops are an opportunity to move the field forward and build community. They may address basic or applied research, best practices, tools, education, industry trends, emerging themes and applications, and critical thinking about existing methodologies and frameworks. Topics should fall within the general scope of HCOMP, CI, or both (see Topics of Interest above), but we also highly encourage emerging research directions that have not yet been fully explored and may even be seen as controversial.

We welcome traditional workshop formats that encourage lively debates and focused discussion, as well as other types of topic-specific activities, such as tutorials or roundtables. Each workshop should generate ideas that will give the HCOMP and CI communities a fresh way of thinking about the topic or suggest promising directions for future work.

General Submission Instructions

 

Submission Templates

All submissions should use one of the following templates and must be converted to PDF at the time of submission:

All authors should submit manuscripts for review in a single column format. For the Word Template, follow the embedded instructions to apply the paragraph styles to your various text elements.

To use the LaTeX Template within Overleaf, select New Project → Upload Project and select the .zip file downloaded from the link above. Please use the manuscript document class to prepare your manuscript. On the first active line of the Code or Visual Text Editor, replace \documentclass[sigconf]{acmart} with \documentclass[manuscript]{acmart} to create a single-column format. Please review the LaTeX documentation and ACM’s LaTeX best practices guide should you have any questions.

Policy on Using Large Language Models (LLMs) for Paper Writing

In line with other SIGCHI conferences’ (e.g., CHI), and computing conferences’ (e.g., CVPR and KDD), HCOMP and CI 2026 employ the following policy on the use of Large Language Models in paper writing.

Text generated from a large-scale language model (LLM), such as ChatGPT, must be clearly marked where such tools are used for purposes beyond editing the author’s own text. Please carefully review the ACM Policy on Authorship before you use these tools. The SIGCHI blog post describes approaches to acknowledging the use of such tools and we refer to it for guidance. Note that the LaTeX template will default to hiding the Acknowledgements section while in review mode; please make sure that any LLM disclosure is available in your submitted version. We will investigate submissions brought to our attention and desk reject papers where LLM use is not clearly marked or where an LLM is not appropriately used (e.g., including fake references generated by LLM, relying on AI-tools to generate ideas in the manuscript, etc.).

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, HCOMP and CI 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:

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 flagged as “highly irresponsible,” we will investigate the review. Example cases of highly irresponsible reviews include: reviews that violate the above-mentioned LLM policy, missing or one-sentence reviews, reviews not relevant to the paper or that miss a substantial portion of the paper. Highly irresponsible reviews do not include cases where reviewers merely have some misunderstandings, miss small parts of the paper, or hold a different opinion from other reviewers or the PC. If the 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.

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. HCOMP and CI 2026 will enforce this double-blind review policy, and any submissions that fail to meet these anonymity requirements will be desk rejected.
