Uncertainty Management in Logic Programming: Simple and Effective Top-Down Query Answering

We present a simple, yet general top-down query answering procedure for logic programs managing uncertainty. The main features are: (i) the certainty values are taken from a certainty lattice; (ii) computable functions may appear in the rule bodies to manipulate certainties; and (iii) we solve the problem by a reduction to an equational systems, for which we device a top-down procedure.
