Satisfiability Model Visualization Plugin for Deep Consistency Checking of OWL Ontologies

We present an original Protégé plugin developed for the deep consistency checking of OWL ontologies. The plugin constructs and visualizes a minimal satisfiability model of the ontology, which is likely to uncover potential ontological errors: if the constructed model contradicts the author’s intentions, then the ontology itself is either wrong or incomplete. A satisfiability model is generated using Mace4 , a first-order logic (FOL) finite model builder, from the FOL formulas corresponding to the OWL ontology definition. The constructed satisfiability model is visualized using an original music score notation plugin of Protégé.
