This Prolog-Day Symposium will present the highlights of the Year of Prolog, celebrating the 50th anniversary of the birth of Prolog. The Symposium will include the award of the inaugural edition of the ALP Alain Colmerauer Prolog Heritage Prize (in short: the Alain Colmerauer Prize) for recent practical accomplishments that highlight the benefits of Prolog-inspired computing for the future, and presents the Prolog education initiative for introducing young people to Prolog. The Symposium will visit the past, present, and future of Prolog and explore its advantages as a language for explainable AI and for computing more generally. The day includes four sessions; the last session is devoted to the Alain Colmerauer prize. The other three sessions consist of presentations and round tables.
