New automata approach achieves EXPTIME for description logics

By PulseAugur Editorial · [1 sources] ·

This research paper introduces an automata-based approach to analyze description logics with concrete domains, aiming to determine the decidability and complexity of consistency problems. The proposed method enriches transitions with symbolic constraints, achieving an optimal upper bound of EXPTIME for the non-emptiness problem under specific concrete domain properties. The authors demonstrate that this approach can be extended to include features like inverse roles and functional role names while maintaining EXPTIME-membership, highlighting the robustness of constraint automata.

    Robustness of Constraint Automata for Description Logics with Concrete Domains

    arXiv:2601.19644v2 Announce Type: replace-cross Abstract: Decidability or complexity issues about the consistency problem for description logics with concrete domains have already been analysed with tableaux-based or type elimination methods. Concrete domains in ontologies are es…
