Abstract

In this paper we study the possibility of providing causal explanations for preferred answer sets, such as those obtained from logic programs with ordered disjunction (LPODs). We use a recently defined multi-valued semantics for answer sets based on a causal algebra and consider its direct application to LPODs by several illustrating examples. We also explain the limitations of this simple approach and enumerate some open topics to be explored in the future.
