Call for Papers 21st Conference on Computer Science and Intelligence Systems FedCSIS 2026 (IEEE #69809; indexing: DBLP, SCOPUS, Web of Science; www.fedcsis.org) Riga, Latvia, August 23-26, 2026 (on-site/in person) (submission deadline: April 15, 2026; hard deadline) The mission of the FedCSIS Conference Series is to provide a presentation, discussion and a publication forum in computer science and intelligence systems. The conference invites researchers and practitioners from around the world to contribute research results focused on their scientific and professional interests in a chosen area. The FedCSIS conference consists of the Main Track and Thematic Session. Papers, submitted to the Main Track can be assigned, by their authors, to Topical Areas. Based on the scope of the contribution, Topical Area Curators select its reviewers from the FedCSIS Program Committee. Besides the Main Track, the authors may prefer to submit their papers to Thematic Sessions, which provide in-depth coverage of specific areas related to the intelligence systems. For all five Topical Areas, situated within a general domain of Computer Science, the continually emerging topic of Intelligence Systems stands as the common denominator. All Thematic Sessions also refer to the Intelligence Systems from different perspectives. They are regarded as a path toward introducing more Intelligence into Computer Science and IT. Main Track: * Topical Area 1: Advanced Artificial Intelligence Approaches * Topical Area 2: Intelligent Data Processing and Infrastructure * Topical Area 3: Security of AI and AI for Security * Topical Area 4: Intelligence Technologies for Business and Society * Topical Area 5: Intelligent Software, System, and Service Engineering Thematic Sessions (listed in alphabetic order): * Agentic AI in SC - Agentic AI in Smart Cities * AgriAI - AI in Agriculture * AI-HuSo - AI in Digital Humanities, Computational Social Sciences and Economics Research * AIWAVOM - AI for Inland Water, Atmospheric Environments, and Ocean Modelling * APL - Advances in Programming Languages * CANA - Computer Aspects of Numerical Algorithms * CNLPS - Challenges for Natural Language Processing * CO - Computational Optimization * DSH - Data Science in Health, Ecology and Commerce * EDUC-AI-TION - Education & AI systems * IoT-ECAW - Internet of Things Enablers, Challenges and Applications * ISM - Information Systems Management * MDASD - Model Driven Approaches in System Development * MMAP - Multimedia Applications and Processing * NEMESIS - International Forum on Cyber Security, Privacy, and Trust * SLSAS - Self Learning and Self Adaptive Systems Professor Zdzislaw Pawlak Awards: * Best Paper Award (600 Euro): the best out of all papers accepted to the conference. * Young Researcher Award (400 Euro): the best out of papers whereby all authors are younger than 40 years. * Industry Cooperation Award (400 Euro): the best out of papers whereby there are at least two different authors, one working in academia and another one in industry. * International Cooperation Award (400 Euro): the best out of papers whereby there are at least two different authors working in institutions located in two different countries. Important dates: * Paper submission (no extensions): 15.04.2026 * Position paper submission: 19.05.2026 * Author notification: 16.06.2026 * Final paper submission, registration: 30.06.2026 * Early registration discount: 20.07.2026 * Conference date: 23-26.08.2026 Paper submission: + Papers should be submitted by April 15, 2026 (strict deadline, no extensions, submission via EasyChair: https://easychair.org/conferences/?conf=fedcsis2026). + Authors should submit their work in English, carefully checked for correct grammar and spelling, using the on-line submission procedure. The guidelines for paper formatting provided at the conference website (https://2026.fedcsis.org/for_authors) must to be used for all submitted papers. The required submission format is the same as the camera-ready format. Please check, and carefully follow, the instructions and templates provided. + Papers that are out of the conference scope, or that contain any form of (self)plagiarism will be rejected without reviews. Statement concerning Generative AIs: Recognizing the developing issue that affects all academic disciplines, we would like to state that, in principle, papers that include unedited text generated from Generative AI (GenAI), including large language models, are prohibited. If the author(s) uses GenAIs to prepare technical aspects of the research(e.g., use of GenAI-generated program code in experiments or simulations), this fact must be clearly marked in the paper, along with an analysis of the impact of this approach on the research results. In addition, it is permissible to use GenAI models at the stage of editorial correction, as long as the changes made are minor and do not substantively affect the article. It should be emphasized that full responsibility for the content of the publication lies with the author(s). Inappropriate or unethical use of GenAI models in the preparation of an article may result in its rejection.
