AI researchers propose new logic for defeasible conditional obligations

This paper introduces a novel two-tiered semantic framework for modeling defeasible conditional obligations, building upon preference-based semantics for deontic logic. It incorporates a nonmonotonic reasoning mechanism to allow for the withdrawal of obligations when new information arises. The framework utilizes two distinct orderings, ideality and normality, to address limitations in previous approaches and establishes a connection with constrained input/output (I/O) logic. AI

IMPACT Introduces a new formal framework for reasoning about obligations, potentially impacting AI systems that require normative reasoning capabilities.

    Defeasible Conditional Obligation in a Two-tiered Preference-based Semantics (Extended Version)

    arXiv:2604.26977v1 Announce Type: cross Abstract: In response to a concern raised by Horty, this paper develops a two-tiered, preference-based semantic framework for modeling defeasible conditional obligations. The paper extends a Hansson-Lewis style preference semantics for dyad…
