The 24th European Conference on Advances in Databases and Information Systems (ADBIS 2020), the 24th International Conference on Theory and Practice of Digital Libraries (TPDL 2020) and the 16th EDA days on Business Intelligence & Big Data (EDA 2020) were “colocated” online from August 25, 2020 to August 27, 2020, because of the COVID-19 crisis. This joint event was indeed to be held originally in Lyon, France, instead. Keynotes were common to all three conferences. This chapter introduces the five keynote speakers of high scientific profile who made us the honor of giving an invited speech. We thank them very much.
