============== Call for Papers: CONCEPTS 2026 ==================

3rd International Joint Conference on Conceptual Knowledge Structures

August 31st – September 4th, 2026
, in Montpellier, France


https://concepts2026.org/

======================================================================


CONCEPTS 2026 is the third edition of the joint gathering of the three
key communities in the field of Conceptual Knowledge Structures:
* The 30th International Conference on Conceptual Structures (ICCS)

* The 20th International Conference on Formal Concept Analysis (ICFCA)
* The 19th International Conference on Concept Lattices and their
Applications (CLA)

This merger creates a unique venue for researchers and practitioners
working on theoretical and applied aspects of Formal Concept Analysis
(FCA), Conceptual Graphs, and the representation of conceptual
knowledge. The conference welcomes contributions from related areas such
as Artificial Intelligence, data mining, information retrieval,
knowledge management, and Semantic Web while fostering interdisciplinary
exchange with related fields.

(machine learning, Generative AI, Large Language Models etc.), database
theory, software engineering, natural language processing (NLP) …
* Real-World Applications:
Modeling phenomena in digital humanities, cybersecurity, biology,
medicine, social network analysis, robotics …
* Interdisciplinary:
Psychology, philosophy, social sciences and learning spaces related to
conceptual structures ...

\___ 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.
