We would like to express our sincere gratitude to all participants of the International Conferences on: Cognition and Exploratory Learning in the Digital Age (CELDA 2026), Applied Computing (AC 2026), Data Science and Digital Innovation (DSDI 2026) and WWW/Internet (ICWI 2026). Your participation, dedication, and valuable research contributions played a fundamental role in the success of these events. 

We are particularly grateful to everyone who joined us in Lisbon, Portugal, for the opportunity to share knowledge, exchange ideas, discuss emerging challenges, and strengthen connections within the international research community. 

Each year, these conferences bring together researchers, academics, students, practitioners, and professionals from around the world, fostering an enriching environment for collaboration, interdisciplinary dialogue, and the exchange of knowledge and experiences. Through your contributions and engagement, you helped create a stimulating forum for exploring current developments, sharing innovative perspectives, and advancing research across the diverse fields covered by our conferences. 

We extend our heartfelt thanks to everyone who contributed to making these events a success. Your continued support and participation are greatly valued, and we look forward to welcoming you again next year!
