Bridging between LegalRuleML and TPTP for Automated Normative Reasoning (extended version)

TL;DR

This paper introduces a translation framework connecting LegalRuleML and TPTP formats, enabling automated normative reasoning across legal and logical systems with practical demonstrations.

Contribution

It defines a logic-pluralistic normative reasoning language in TPTP, provides a translation scheme from LegalRuleML, and proposes a flexible architecture for automated normative reasoning.

Findings

Successful translation between LegalRuleML and TPTP fragments

Implementation of normative reasoning with three different logics

Demonstration of the approach's flexibility and applicability

Abstract

LegalRuleML is a comprehensive XML-based representation framework for modeling and exchanging normative rules. The TPTP input and output formats, on the other hand, are general-purpose standards for the interaction with automated reasoning systems. In this paper we provide a bridge between the two communities by (i) defining a logic-pluralistic normative reasoning language based on the TPTP format, (ii) providing a translation scheme between relevant fragments of LegalRuleML and this language, and (iii) proposing a flexible architecture for automated normative reasoning based on this translation. We exemplarily instantiate and demonstrate the approach with three different normative logics.
