2022: The Year of Prolog

Organized by The Association for Logic Programming and The Prolog Heritage Association

In the summer of 1972, Alain Colmerauer and his team in Marseille developed and implemented the first version of the logic programming language Prolog. Together with both earlier and later collaborations with Robert Karl's and his colleagues in Edinburgh, this work laid the practical and theoretical foundations for the Prolog and logic programming of today. Prolog and its related technologies soon became key tools of symbolic programming and Artificial Intelligence.

The Year of Prolog celebrated the 50th anniversary of these events and highlighted the continuing significance of Prolog and Logic Programming both for symbolic, explainable AI, and for computing more generally. It also aimed to inspire a new generation of students, by introducing them to a more human-friendly, logic-based approach to computing.

The initiatives of the Year of Prolog included:

A Scientific Committee oversaw the scientific activities of the Year of Prolog, supported by other committees in charge of the various initiatives involved.

NOTE: The followup activities from the Year of Prolog are grouped in the Online Prolog Community.




The Year of Prolog and its activities, including the Alain Colmerauer Prize, are sponsored by the Association for Logic Programming, the Prolog Heritage Association, the AI Journal, Institut Carnot Cognition, and Institut Fredrik Bull, among others.
