Abstract

We present an algorithm that-given a set of clauses S saturated under some semantic refinements of the resolution calculus-automatically constructs a Herbrand model M of S. M is represented by a set of atoms with equality and disequality constraints interpreted over the finite tree algebra, hence the problem of evaluating first-order formulae in M is decidable.
