This book presents selected papers from the 14th International Conference on Information Technology and its Applications (CITA 2025) which will be co-organized by Vietnam-Korea University of Information and Communication Technology (Vietnam), Cambodia Academy of Digital Technology (Cambodia) and King Mongkut’s University of Technology North Bangkok (Thailand), and will take place in Phnom Penh, Cambodia on July 14–15, 2025. The conference also is supported and accompanied by the research and training institutions belonging to the ASEAN Consortium for Innovation and Research (ACIR) as well as the Vietnam ICT Association of Faculties-Institutes-Schools-Universities (FISU Vietnam), Wroclaw University of Science and Technology (Poland), University College Dublin (Ireland), Springer and SMCS (IEEE). Over the past 14 years of establishment and development, CITA has become an international scientific conference with a prestigious brand in the scientific commu nity not only in Vietnam but also around the world in the field of ICT and digital economy. All papers submitted to CITA 2025 are reviewed seriously, closely and thor oughly by 2–5 reviewers with appropriate expertise, with professional advice from reputable scientists in the fields of information and communication technology, digital economy such as Prof. D.Sc. Ngoc Thanh Nguyen (Chair of IEEE SMC Technical Committee on Computational Collective Intelligence, Wroclaw University of Science and Technology, Poland), Prof. Dr. Christian Boitet (Grenoble Univer sity, France), Prof. Dr. Thanh Thuy Nguyen (Chairman of FISU Vietnam, VNU University of Engineering and Technology, Vietnam), Prof. Dr. Tzung-Pei Hong (National University of Kaohsiung, Taiwan), Prof. Dr. David Camacho (Universidad Autonoma de Madrid, Spain), Prof. Dr. Nitesh Chawla (University of Notre Dame, USA), Prof. Dr. Franck Leprévost (University of Luxembourg, Luxembourg), Assoc.
