This is enabled by the adoption of the logic CFDnc-forall, a member of the CFD family of description logics (DLs). Of particular note is that this logic can fully simulate DLlite-F, a member ofthe DL-Lite family commonly used in the OBDA setting. Our main results present efficient algorithms that allow computation ofcertain answers with respect to CFDnc-forall nowledge bases, facilitating direct access to a pre-existing row-basedrelational encoding of the data without any need for mappings to triple-based representations.","doi":null,"url":"https://ijcai.org/proceedings/2016/182","pdf":"https://ijcai.org/proceedings/2016/0182.pdf","markdown":"https://ijcai.org/proceedings/2016/182.md","bibtex":"https://ijcai.org/proceedings/2016/bibtex/182","volume":{"slug":"2016","title":"Proceedings of the Twenty-Fifth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2016","url":"https://ijcai.org/proceedings/2016/","year":2016,"location":"New York, NY, USA","dates":"9–15 July 2016","editors":"Subbarao Kambhampati","isbn":"978-1-57735-770-4; 978-1-57735-771-1","publisher":"AAAI Press / International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":null,"track":"","number":182,"pages":{"first":1258,"last":1263},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
