Call for System Demonstrations

Overview

AACL-IJCNLP 2026 (the 5th Conference of the Asia-Pacific Chapter of the Association for Computational Linguistics and the 15th International Joint Conference on Natural Language Processing) welcomes proposals for system demonstrations that showcase innovative NLP systems, ranging from research prototypes to production-ready solutions. Demonstrations should highlight technological advancements for an international audience of researchers and practitioners.

Topics span all areas of NLP and computational linguistics, including (but not limited to):

  • NLP Systems: Natural language processing systems or system components
  • Application Systems: Application systems leveraging language technology components
  • Research Tools: Software tools supporting NLP research
  • Demo & Evaluations: Software for demonstration or evaluation purposes
  • Educational Tools: Software supporting NLP learning or education
  • Data Visualization: Tools for data visualization and annotation
  • Model Inspection: Tools for model inspection and analysis
  • Development Tools: Development tools and frameworks for NLP

Demonstrations should also exhibit:

  • Open Source Priority: Preference for systems publicly available as open-source/open-access solutions.
  • Industrial Innovation: Showcasing industrial systems with technological innovation in NLP applications.

Best Demo Award: A Best Demo Award will be evaluated and conferred by a committee member based on interactions with demos during the conference.

Important Note: “Commercial sales and marketing activities are not appropriate in the Demonstrations Program” — such activities should be arranged through the Exhibit Program instead.

Submission Guidelines

Submissions must include:

A Paper

The accompanying paper should outline the system’s design with sufficient detail for evaluating its validity, quality, and relevance to NLP. Technical details and visual aids (screenshots, snapshots, diagrams) are required. Papers may address:

  • What problem does the system address?
  • Why is the system important, and what is its impact?
  • What is the novelty in the approach or technology?
  • Who is the target audience?
  • How does the system work?
  • How does it compare with existing systems?
  • How is the system licensed?
  • How was the system evaluated (including user studies or human evaluation)?

Submissions lacking any form of evaluation may face desk rejection.

Length: Up to 6 pages, plus 2 pages for references and informative appendices. Longer submissions will be desk rejected. Papers must conform to the AACL-IJCNLP 2026 official style guidelines, be in PDF format, and describe original, unpublished work (publication is archival). Use the official template and submit via OpenReview (link TBD). Templates are available at the ACL Rolling Review CFP page.

A Demonstration Video

A screencast of up to 2.5 minutes demonstrating the system. The screencast supports paper review and will not be published unless requested. If a screencast isn’t feasible, a video of user interaction may be used. Simple production is encouraged. Either include a link in the paper (YouTube or similar) or submit it as MPEG4 supplementary material.

The video should focus on:

  • Demonstrating Key Feature
  • Showing System Workflow
  • Highlighting Unique Capabilities
  • Adding in Clear Video Narration

Live Demo Website or Installable Package

A link to a live demo or downloadable installation package is required. Submissions without such a link will be desk rejected unless justified (e.g., specialized hardware needed).

Multiple Submission Policy

The track follows the main conference’s Multiple Submission Policy. Submissions must not be under review or published elsewhere. Authors submitting multiple demo papers must ensure content/results do not overlap by more than 25%.

Reviewing Policy

Reviewing is single-blind with no rebuttal. Authors should include their names and affiliations and may cite their own work.

Ethics Policy

Authors must follow the ACM Code of Ethics. Research should consider ethical implications of the system and data. Additional space beyond page 6 is allowed for broader impact or ethical discussion. An ethics section isn’t mandatory, but its omission in sensitive domains may lead to rejection. Papers flagged for ethical concerns will be reviewed by the ethics committee.
