Towards Scalable and Complete Query Explanation with OWL 2 EL Ontologies
2015
Proceedings of the 24th ACM International on Conference on Information and Knowledge Management - CIKM '15
Ontology-mediated data access and management systems are rapidly emerging. Besides standard query answering, there is also a need for such systems to be coupled with explanation facilities, in particular to explain missing query answers (i.e. desired answers of a query which are not derivable from the given ontology and data). This support is highly demanded for debugging and maintenance of big data, and both theoretical results and algorithms proposed. However, existing query explanation
