Mapping deontic operators to abductive expectations

A number of approaches to agent society modeling can be found in the Multi-Agent Systems literature which exploit (variants of) Deontic Logic. In this paper, after briefly mentioning related approaches, we focus on the Computational Logic (CL) approach for society modeling developed within the UE IST-2001-32530 Project (named SOCS), where obligations and prohibitions are mapped into abducible predicates (respectively, positive and negative expectations), and norms ruling the behavior of members are represented as abductive integrity constraints. We discuss how this abductive framework can deal with Deontic Logic concepts, by introducing additional integrity constraints.
