This page will be updated with questions (and answers) as they arise. Please check back regularly. If you do not find an answer to your question here, you are welcome to contact the IJCAI-25 program chair at pcchair@2025.ijcai.org, but please make sure that you have read IJCAI-25 CFP and the current FAQ first.
Yes, you can.
Yes. This applies more generally to papers presented in any non-archival venue (that is, as long as there are no formally published proceedings with a publisher, in general with a DOI, ISBN, or ISSN).
IJCAI requires that all submissions be anonymized. To facilitate this, we require that the authors follow both the letter and spirit of the normal anonymization guidelines. Please ensure also that the PDF meta-data does not reveal the authors’ identities. Any paper that obviously violates this requirement will be rejected without review.
Yes. You are allowed to submit papers where the notification will occur between the IJCAI abstract and full-paper deadlines. However, if the paper is accepted during this period you must withdraw the IJCAI submission. If the paper is rejected during this period then it is considered as a resubmission and you are required to upload the resubmission information.
Yes. Authors must declare whether their paper has been rejected from another peer-reviewed conference in the last 12 months before the submission. They will be requested to upload the latest rejected version (anonymized if necessary) with the reviewer’s comments; a cover letter responding to the reviews is optional.
No. Submission deadline for supplementary file and/or resubmission file is the same as that for full paper.
Your resubmission information will be visible only to reviewers after they enter their review.
A paper is considered a ‘student paper’, and thus a potential winner of the ‘Best Student Paper Award’, when the first author is a student who, at the time of submission, has not obtained any PhD degree yet. When submitting a paper, this should be indicated by marking the appropriate checkbox.
Title: It is highly recommended not to go above two lines in the IJCAI format. Three lines is a strict maximum.
Abstract: There is no word limit for abstracts. However, 200 words is a nice upper limit that authors should always apply.
By ‘abstract submission’ we mean that you should register your paper by providing a title and a short abstract. This abstract is intended to help program committee members get papers that match their expertise. There are neither abstract-only submissions, nor any paper-only submissions: in all cases, you must submit an abstract, and then you must submit a full paper. (See abstract submission and paper submission deadlines on the website).
Yes. You will be allowed to change the author-order if the paper is accepted. You will not be allowed to add or remove authors.
Please ask your co-authors to log in to the submission system and fill in author information. Please make sure that you use the email address they prefer to use in CMT. As an author or co-author, once you log in, you can see all papers under your name or account (if you have multiple accounts/email addresses, you should check all your accounts). If an author finds any submission, for which they did not give their consent to submit, they should report to the program chair immediately.
Authors are not allowed to submit their papers to venues with formally published proceedings during the IJCAI 2025 review period. These restrictions do not apply to workshops and similar specialized presentations with a limited audience and without published proceedings.
If you have difficulty anonymizing the reviews, please consult with the IJCAI Ethics Chair (ethics@2025.ijcai.org) on how to handle that situation
After completing your paper submission, please go to Author Console and click “Upload Supplementary Material” under column “Action”. Then you will find two entries: one for technical appendix and the other for resubmission information.
