The 2nd Conference of the Asia-Pacific Chapter of the Association for Computational Linguistics and the 12th International Joint Conference on Natural Language Processing

November 20-23, 2022

Online only

Call for Systems Demonstrations

The AACL-IJCNLP 2022 System Demonstration Program Committee invites proposals for the Demonstrations Program. Submissions may range from early research prototypes to mature production-ready systems. Of particular interest are publicly available open-source or open-access systems. We strongly encourage demonstrations of industrial systems that are technologically innovative given the current state of the art of theory and applied research in computational linguistics.

Areas of interest include all topics related to theoretical and applied computational linguistics, such as (but not limited to) the topics listed on the main conference website: Submitted systems may be of the following types:

  • Natural Language Processing systems or system components

  • Application systems using language technology components

  • Software tools for computational linguistics research

  • Software for demonstration or evaluation

  • Software supporting learning or education

  • Tools for data visualization and annotation

  • Development tools

Accepted submissions will be published in a companion volume of the AACL-IJCNLP 2022 conference proceedings, and will be presented during a demo session with an accompanying poster.

Please note: Commercial sales and marketing activities are NOT appropriate in the Demonstration Program and should be arranged as part of the Exhibit Program.

Best Demo Award

AACL-IJCNLP 2022 will have a Best Demo Award, honoring a system demonstration that brings together conceptual innovation and practical usability, and encouraging researchers to make their code publicly available in the form of an effective, easy-to-use, runnable system.

Important Dates

  • Paper submission deadline: Friday August 19, 2022

  • Notification of acceptance: Monday October 3, 2022

  • Camera-ready submission: Thursday October 20, 2022

Note: All deadlines are 11:59PM UTC-12:00 ("anywhere on Earth").

Demo Details

Developers should outline the design of their system and provide sufficient details to allow the evaluation of its validity, quality, and relevance to computational linguistics. Discussion of limitations, use cases as well as related systems should also be included. If the demo has the potential for ethical concernss (for instance, displaying medical patient data), details should be given as to how the ethical issues are resolved in the demo (for instance, only anonymised records are used).

Pointers to web sites running a demo preview will also be helpful. For non web-based demos, it is possible to submit a short (~2 minute) screencast video demonstrating the system. This screencast will be used to evaluate the paper, but won’t be published unless requested. We encourage the authors to include visual aids (e.g., screenshots, snapshots, or diagrams) in the paper. However, there will be a place on the START website to upload additional material, if needed. If you choose to submit a screencast, please upload the video to some hosting site (YouTube, Vimeo, etc.) and include the link in your submission.

Demo submissions should also clearly indicate if any computer equipment is expected to be provided by the local organizer. If so, please specify desired hardware platform, hard disk and memory capacity, operating system and other software needed in order to run the demo.

Demo Submission

Submission is electronic, using the Softconf START conference management system at

Style files should meet the requirements of the AACL-IJCNLP main conference. Submissions may consist of up to 6 pages (including references). Submissions must conform to the AACL-IJCNLP 2022 official style guidelines ( and they must be in PDF format. The submissions have to be original work (unpublished), as the publication in AACL-IJCNLP will be archival.

Reviewing Policy

Reviewing will be single-blind, so authors do not need to conceal their identity. The paper should include the authors’ names and affiliations. Self-references are also allowed. Papers with unresolved ethical issues will not be accepted.
