Abstract
Justification logics are epistemic logics that include explicit justifications for an agent’s knowledge. In the present paper, we introduce a justification logic \(\mathcal{JALC}\) over the description logic \(\mathcal{ALC}\). We provide a deductive system and a semantics for our logic and we establish soundness and completeness results. Moreover, we show that our logic satisfies the so-called internalization property stating that it internalizes its own notion of proof. We then sketch two applications of \(\mathcal{JALC}\): (i) the justification terms can be used to generate natural language explanations why an \(\mathcal{ALC}\) statement holds and (ii) the terms can be used to study data privacy issues for description logic knowledge bases.
