EXPTIME tableaux with global caching for description logics with transitive roles, inverse roles and role hierarchies

Gore, Rajeev; Nguyen, Linh Anh

Description

The description logic SHI extends the basic description logic ALC with transitive roles, role hierarchies and inverse roles. The known tableau-based decision procedure [9] for SHI exhibit (at least) NEXP-TIME behaviour even though SHI is known to be EXPTIME-complete. The automata-based algorithms for SHI often yield optimal worst-case complexity results, but do not behave well in practice since good optimisations for them have yet to be found. We extend our method for global caching in ALC to...[Show more]
