The 18th National Conference on Computing and Information Technology takes place during a time of exciting but tough changes and contributes to the solution of new problems facing scientists and engineers. New computer interfaces as well as the abilities of machines and services offered have drastically changed within the last few years. And this is only the beginning: obtained research results provide a platform to build upon, ensuring significant progress and achievement of goals. Major contributions to these developments have been brought about by advancements in the area of artificial intelligence, machine learning, natural language processing, speech recognition, image and video processing are essential research and engineering directions, which have made autonomous driving, language assistants, automatic translation and answering systems as well as other innovative applications possible. These developing technologies also reflect the economic change throughout the world, which are increasingly dominated by the enhancement of globalisation. World-wide cooperation (including its competitive aspects) is the only positive way to tackle emerging global problems successfully.
