Towards a Semantic Querying Approach For a Multi-Version OWL 2 DL Ontology

Abstract

The ontology formalizes a given domain of interest along a specific structure for disambiguating and conveying the knowledge semantics. This helps to create an explicit shared consensus on a given domain knowledge. When updating a domain ontology, it is useful to store ontology versions. Indeed, this helps to retrieve old critical knowledge through the different query types which require retrieving knowledge from different versions. Nonetheless, not all versioning approaches support conventional queries for OWL 2 DL ontologies such as cross-version queries. More importantly, they overlook semantic queries which expect retrieving complete answers with implicit knowledge. Our paper aims to present our proposed approach to support ontology engineers in querying an OWL 2 DL ontology and its evolution history.
