In the context of a query over a first order knowledge base, referring expressions to answers are usually constant symbols. This paper motivates and initiates the exploration of allowing more general formulas, called singular referring expressions, to replace constants in this role. Referring expression types play a novel and significant role in analyzing the properties of candidate expressions.","doi":"10.24963/ijcai.2017/668","url":"https://ijcai.org/proceedings/2017/668","pdf":"https://ijcai.org/proceedings/2017/0668.pdf","markdown":"https://ijcai.org/proceedings/2017/668.md","bibtex":"https://ijcai.org/proceedings/2017/bibtex/668","volume":{"slug":"2017","title":"Proceedings of the Twenty-Sixth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2017","url":"https://ijcai.org/proceedings/2017/","year":2017,"location":"Melbourne, Australia","dates":"19-25 August 2017","editors":"Carles Sierra","isbn":"978-0-9992411-0-3","publisher":"International Joint Conferences on Artificial Intelligence Organization","doi_prefix":"10.24963/ijcai.2017"},"section":"Best Sister Conferences","track":"Best Sister Conferences","number":668,"pages":{"first":4791,"last":4795},"keywords":["Artificial Intelligence: knowledge representation and reasoning"],"videos":[],"references":[{"position":1,"raw":"[Areces, Figueira, and Gorín, 2011] Areces, C.; Figueira, S.; and Gorín, D. 2011.
