Epistemic Queries for OWL Knowledge Bases

Presented at: 8th Extended Semantic Web Conference (ESWC2011)

by Anees Ul Mehdi, Sebastian Rudolph, Stephan Grimm

Epistemic querying extends standard ontology inferencing by allowing for deductive introspection. We propose a technique for epistemic querying of OWL2 ontologies not featuring nominals and universal roles by a reduction to a series of standard OWL2 reasoning steps thereby enabling the deployment of off-the-shelf OWL2 reasoning tools for this task. We prove formal correctness of our method, justify the omission of nominals and universal role, and provide an implementation as well as evaluation results.

Keywords: Epistemic Querying, OWL2, Reasoning Interface
