This page states the copyright, reuse, access and fee terms of the IJCAI Proceedings, and who owns and publishes them.
1. Copyright
Authors transfer the copyright of their papers to the International Joint Conferences on Artificial Intelligence Organization (IJCAI), which keeps it. IJCAI is named as the copyright holder in the front matter of each volume and on each paper page. Papers written by U.S. Government employees as part of their employment are not subject to U.S. copyright; their authors certify this instead of transferring copyright.
Authors and their employers keep all rights other than copyright, such as patent rights. They may reuse all or part of the paper in other works of their own, and present the material orally in any forum. For work done under a U.S. Government contract, the U.S. Government may reproduce the paper for its own purposes.
These terms apply to the published papers. The copyright notice at the foot of this website covers the website itself.
2. Reuse
IJCAI publishes the proceedings openly: every paper is free for anyone to read and download, without registration or payment. Within that, the following terms apply.
- Authors may post any version of their paper, including the published version, on their own website, in institutional or subject repositories such as arXiv, and elsewhere, provided that a reference and a link to the published paper and its copyright holder (IJCAI) are clearly visible.
- Preprints: a non-anonymous preprint, for example on arXiv, may be posted before and during review.
- Other reuse, such as republishing a paper or parts of it, needs written permission from IJCAI. Requests go to the IJCAI Executive Director at vsfritz [at] ijcai.org.
3. Access
All IJCAI proceedings, from the first conference in 1969 onwards, are available on ijcai.org, free of charge. No registration, subscription or payment is required to read them. Printed copies can be bought from Curran Associates.
4. Author fees
- There are no article processing charges or page charges.
- Each accepted paper must be presented in person at the conference, both orally and as a poster, by an author who registers for the conference. See Corrections, Retractions, Complaints and Appeals, section 5.
- A submission fee may apply in a given year. It is announced in that year’s call for papers, together with the rules for waiving it, and it has no bearing on review decisions. For IJCAI 2027, a fee of USD 100 applies to each submission and is waived for primary papers, i.e. papers none of whose authors appear on any other submission (Primary Paper Initiative). Its proceeds go exclusively to supporting the IJCAI reviewing community.
5. Identifiers
Every paper has a DOI under the prefix 10.24963, registered with Crossref. Every volume has its own ISBN.
6. Backups
IJCAI keeps electronic backups of the proceedings and registers DOI metadata for every paper with Crossref.
7. Ownership, management and revenue
The proceedings are owned and published by the International Joint Conferences on Artificial Intelligence Organization, a non-profit corporation founded in California in 1969. It is governed by its Board of Trustees and run by the IJCAI Secretariat. Its revenue sources are conference registration, sponsorship, submission fees and the sale of printed proceedings through Curran Associates.
