Abstract

Inference in probabilistic logic languages such as ProbLog, an extension of Prolog with probabilistic facts, is often based on a reduc- tion to a propositional formula in DNF. Calculating the probability of such a formula involves the disjoint-sum-problem, which is computation- ally hard. In this work we introduce a new approximation method for ProbLog inference which exploits the DNF to focus sampling. While this DNF sampling technique has been applied to a variety of tasks before, to the best of our knowledge it has not been used for inference in probabilis- tic logic systems. The paper also presents an experimental comparison with another sampling based inference method previously introduced for ProbLog.
