The Twelfth International Conference on Inductive Logic Programming was held in Sydney, Australia, July 9–11, 2002. Continuing a series of international conferences devoted to Inductive Logic Programming and Relational Learning, ILP 2002 was the central event in 2002 for researchers interested in learning relational knowledge from examples.
