Abstract

In this paper we describe HARNESS, a legal knowledge-based system that is developed in the context of ESTRELLA. This system is primarily aimed at the task of legal assessment, i.e. determining whether some case violates and/or complies with legal norms. We explain how the sound and complete reasoning provided by OWL-DL reasoners is exploited by a careful representation of norms, using examples from law on taxation of gifts. We describe a plugin for Protégé 4 that enables easy experimentation for this system, powered by Pellet.
