Title
Practical Reasoning for Expressive Description Logics
Abstract
Description Logics (DLs) axe a family of knowledge representation formetlisms mainly chauracterised by constructors to build complex concepts and iroles from atomic ones. Expressive role constructors are important in many applications, but can be computationally problematical. We present an algorithm that decides satisfiability of the DL ACC extended with transitive eind inverse roles, role hierarchies, and quaJifying number restrictions. Early experiments indicate that this algorithm is well-suited for implementation. Additionally, we show that ACC extended with just transitive and inverse roles is still in PSPACE. Finally, we investigate the limits of decidability for this family of DLs.
