Software Technologies: 16th International Conference, ICSOFT 2021, Virtual Event, July 6–8, 2021, Revised Selected Papers (Communications in Computer and Information Science, 1622)

The present book includes extended and revised versions of a set of selected papers from the 16th International Conference on Software Technologies (ICSOFT 2021), held as an online event due to the COVID-19 pandemic, during July 6–8, 2021.ICSOFT 2021 received 117 paper submissions from authors in 36 countries, of which 9% were included in this book.The papers were selected by the event chairs and their selection was based on a number of criteria that include the classifications and comments provided by the Program Committee members, and the assessments provided by the session chairs and the program chairs. The authors of selected papers were then invited to submit a revised and extended version of their papers having at least 30% innovative material. The revisions and extensions were verified by the event chairs during this final stage.The purpose of the ICSOFT conference series, which started in 2006, is to bring together researchers, engineers, and practitioners interested in software technologies.The conference areas are “Software Engineering and Systems Development”, “Software Systems and Applications”, and “Foundational and Trigger Technologies”.The papers included in this book contribute to the understanding of relevant trends of current research on software technologies, including– Model-driven software engineering approaches for cyber-physical systems and Internet of Things (IoT) systems;– Artificial intelligence applications for optimization and coordination of complex software systems;– Code refactoring methods for software energy consumption and software architecture recovery;– Frameworks and methodologies for context-aware reconfigurable software applications and socio-technical systems; and– Software engineering tools for automated software engineering and software evaluation.We would like to thank all the authors for their contributions and also the reviewers who have helped in ensuring the quality of this publication.
