This book constitutes the thoroughly refereed post-proceedings of the
23rd International Conference on Inductive Logic Programming, ILP 2013,
held in Rio de Janeiro, Brazil, in August 2013.
The 9 revised extended papers were carefully reviewed and selected from
42 submissions. The conference now focuses on all aspects of learning in
logic, multi-relational learning and data mining, statistical relational
learning, graph and tree mining, relational reinforcement learning, and
other forms of learning from structured data.
