These users are not typically familiar with graph query languages such as SPARQL, and may not be familiar with the knowledge graph's structure. In this extended abstract, we provide a summary of our work on a language and visual interface -- called RDF Explorer -- that help non-expert users to navigate and query knowledge graphs. A usability study over Wikidata shows that users successfully complete more tasks with RDF Explorer than with the existing Wikidata Query Helper interface.","doi":"10.24963/ijcai.2020/666","url":"https://ijcai.org/proceedings/2020/666","pdf":"https://ijcai.org/proceedings/2020/0666.pdf","markdown":"https://ijcai.org/proceedings/2020/666.md","bibtex":"https://ijcai.org/proceedings/2020/bibtex/666","volume":{"slug":"2020","title":"Proceedings of the Twenty-Ninth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2020","url":"https://ijcai.org/proceedings/2020/","year":2020,"location":"Yokohama","dates":"January 2021 (postponed from 11-17 July 2020)","editors":"Christian Bessiere","isbn":"978-0-9992411-6-5","publisher":"International Joint Conferences on Artificial Intelligence Organization","doi_prefix":"10.24963/ijcai.2020"},"section":"Sister Conferences Best Papers","track":"Sister Conferences Best Papers","number":666,"pages":{"first":4785,"last":4789},"keywords":["Multidisciplinary Topics and Applications: Databases","Knowledge Representation and Reasoning: Semantic Web"],"videos":[{"label":"Video","url":"https://videos.ijcai20.org/27023/file_27023.m3u8","length_sec":847,"provider":"hls"}],"references":[{"position":1,"raw":"[Angles et al., 2017] Renzo Angles, Marcelo Arenas, Pablo Barceló, Aidan Hogan, Juan L.
