Abstract

Conditionals ("if-then-rules") are most important objects in knowledge representation, commonsense reasoning and belief revision. Due to their non-classical nature, however, they are not easily dealt with. This paper presents a new approach to conditionals, which is apt to capture their dynamic power peculiarly well. We show how this approach can be applied to represent conditional knowledge inductively. In particular, we generalize system-Z* as an appropriate counterpart to maximum entropy-representations in a semi-quantitative setting.
