Conf. on Formal Concept Analysis (ICFCA) 17th Intl. Conf. on Concept Lattices and their Applications (CLA) September 9–13 2024, Cádiz, Spain Website: https://concepts2024.uca.es <https://concepts2024.uca.es> Email contact address: concepts24(a)lists.cs.uni-kassel.de <mailto:concepts24@lists.cs.uni-kassel.de> The 1st International Joint Conference on Conceptual Knowledge Structures (CONCEPTS) 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. This new conference aims to continue the tradition and standards of previous conferences and become a key annual meeting to take along all members of the three communities of CLA, ICCS, and ICFCA and to keep abreast of the advances and new challenges in the field. Main topics include but are not limited to: - Formal concept analysis: concept lattices, implications, algorithms and computational complexity - Conceptual graphs, graph-based models for human reasoning - Knowledge spaces and learning spaces - Ontologies, semantic web, knowledge graphs - Conceptual structures in natural language processing and linguistics - Conceptual knowledge acquisition and management - Conceptual knowledge discovery, data analysis, and visualization - Probabilistic approaches to conceptual knowledge representation and knowledge discovery - Approximation techniques in application to conceptual structures - Bridging conceptual structures to information sciences, artificial intelligence, data mining, machine learning, information retrieval, database theory, software engineering, and other areas of computer science - Understanding real-world data and modeling real-world phenomena with conceptual structures *Submission details:* Submissions are invited on significant, original (previously unpublished) research on the topics of the conference. All accepted submissions will be refereed, by following three different modalities: * journal track papers, up to 26 pages, to be published in a special issue of the International Journal of Approximate Reasoning (IJAR) <https://www.sciencedirect.com/journal/international-journal-of-approximate-reasoning>; * regular papers up to 16 pages and short papers up to 8 pages, 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. *Important dates and submission instructions:** * /***Journal track submissions***/ - Full paper submission: March 6, 2024 - Paper reviews sent to authors: May 3, 2024 - Revised submission: June 3, 2024 - Notification of acceptance: June 30, 2024 Manuscripts must be submitted via the International Journal of Approximate Reasoning online submission system (Editorial Manager®): https://www2.cloud.editorialmanager.com/ija/default2.aspx <https://www2.cloud.editorialmanager.com/ija/default2.aspx>.
