Elementary formal systems are a kind of logic programs. We give a comprehensive relationship model for a broad range of classes of elementary formal systems (EFS) and Prolog Programs along with their learnability results in the frameworks of learning in the limit, learning from queries, learning from entailment, and statistical framework of probably approximately correct (PAC) learning. The relationship model accompanies the proofs of containment, partial containment, and/or incompatibilities present among these classes. Further, we study exact learning of two classes of Prolog programs (or...
