Submission Tracks
CONCEPTS 2026 features three distinct submission tracks: the journal IJAR track, the regular LNAI track and the Nectar track. A paper may be submitted to only one of the three tracks and will undergo a peer review process. All accepted papers have to be presented on-site at the conference. The IJAR and LNAI tracks accept original substantial contributions in the topics of the conferences. The Nectar track accepts substantial contributions that have been published in the past two years in related venues (conferences or journals).
- Journal Track (IJAR)
Accepted papers in this track will be published in a Special Issue of the International Journal of Approximate Reasoning (IJAR).
Format: Full papers in the format of the IJAR journal.
- Regular Track (LNAI)
Accepted papers in this track will be published in the conference
proceedings within the Springer Lecture Notes in Artificial Intelligence (LNAI) series.
Format: Papers up to 16 pages (long paper) or up to 8 pages (short paper), including references, in Springer LNCS format.
- Nectar Track
Accepted papers in this track will be published in the front matter of the Springer LNAI proceedings.
Format: 1 page summary, in Springer LNCS format.
