Dear All, Please consider submitting your work to the CONCEPTS conference or the Special Issue of the International Journal of Approximate Reasoning. More details are given below. The PC Chairs of CONCEPTS 2025 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 2nd International Joint Conference on Conceptual Knowledge Structures (CONCEPTS 2025) Cluj-Napoca, România- September, 8th-12th, 2025 https://concepts2025.conference.ubbcluj.ro/ 29th Intl. Conf. on Conceptual Structures (ICCS) 19th Intl. Conf. on Formal Concept Analysis (ICFCA) 18th Intl. Conf. on Concept Lattices and their Applications (CLA) CONCEPTS, the International Conference on Conceptual Knowledge Structures is a merger of the three conferences CLA, ICCS, and ICFCA, which have been essential venues for researchers and practitioners working on theoretical and applied aspects of formal concept analysis and representation of conceptual knowledge, as well as closely related areas, such as data mining, information retrieval, knowledge management, and discovery. CONCEPTS 2025, the second conference in this new series, aims to continue the tradition and standards of previous conferences and to become a key annual meeting for all members of the three communities, CLA, ICCS, and ICFCA, to keep abreast of the advances and new challenges in the field. Main topics include but are not limited to: * Fundamental aspects of Formal Concept Analysis (e.g., FCA theory, concept lattices, algorithms and computational complexity) * Conceptual graphs, graph-based models for human reasoning * Knowledge spaces and learning spaces * Fuzzy, relational, and/or triadic conceptual structures * Conceptual knowledge acquisition, management, exploration, analysis, and/or visualization * Probabilistic or approximative approaches to conceptual knowledge * Bridging conceptual structures to information sciences, artificial intelligence, data mining, machine learning, information retrieval, database theory, software engineering, and other areas of computer science * Ontologies, semantic web, knowledge graphs, and their relation to conceptual knowledge structures such as concept lattices and conceptual graphs. * Conceptual structures in natural language processing and linguistics * Understanding real-world data and modeling real-world phenomena with conceptual structures (e.g., applications in digital humanities, cybersecurity, biology, medicine, social network analysis) * Psychology, philosophy, and conceptual structures. Submission details: Submissions are invited on significant, original (previously unpublished) research on the topics of the conference: * Journal-track papers up to 26 pages, to be published in a special issue of the <https://www.sciencedirect.com/journal/international-journal-of-approximate-reasoning> International Journal of Approximate Reasoning (IJAR)<https://www.sciencedirect.com/journal/international-journal-of-app…ng>; * Regular papers up to 16 pages and short papers up to 8 pages are to be published by Springer in the LNAI series as a proceedings volume. All submissions will be subject to single-blind peer review. Accepted papers have to be presented at the conference on-site. Therefore, at least one author per paper has to register timely and attend the conference on-site.
