Focusing on relational data sources, we discuss the main ingredients of ontology-based data access, key theoretical results, techniques, applications and future challenges.","doi":"10.24963/ijcai.2018/777","url":"https://ijcai.org/proceedings/2018/777","pdf":"https://ijcai.org/proceedings/2018/0777.pdf","markdown":"https://ijcai.org/proceedings/2018/777.md","bibtex":"https://ijcai.org/proceedings/2018/bibtex/777","volume":{"slug":"2018","title":"Proceedings of the Twenty-Seventh International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2018","url":"https://ijcai.org/proceedings/2018/","year":2018,"location":"Stockholm","dates":"13-19 July 2018","editors":"Jérôme Lang","isbn":"978-0-9992411-2-7","publisher":"International Joint Conferences on Artificial Intelligence Organization","doi_prefix":"10.24963/ijcai.2018"},"section":"Survey track","track":"Survey track","number":777,"pages":{"first":5511,"last":5519},"keywords":["Knowledge Representation and Reasoning: Knowledge Representation Languages","Knowledge Representation and Reasoning: Logics for Knowledge Representation","Knowledge Representation and Reasoning: Description Logics and Ontologies","Multidisciplinary Topics and Applications: Intelligent Database Systems"],"videos":[],"references":[{"position":1,"raw":"[Abiteboul et al., 1995] S.
