New DL Ontology Semantics Enhance Confidentiality and Tractability

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced a new semantics for Controlled Query Evaluation (CQE) in Description Logic (DL) ontologies, aiming to improve computational tractability and confidentiality preservation. The existing GA- and IGA-entailment semantics for CQE have been found to be computationally intractable for DL-Lite_R ontologies and, in the case of IGA, may not fully satisfy indistinguishability properties. The proposed new semantics, based on minimal policy violation (MPV), offers a sound approximation while ensuring indistinguishability and can be decided in polynomial time for DL-Lite_R ontologies.
