After a general introduction, we motivate and contrast various graph-based data models and query languages that are used for knowledge graphs. We discuss the roles of schema, identity, and context in knowledge graphs. We explain how knowledge can be represented and extracted using a combination of deductive and inductive techniques. We summarise methods for the creation, enrichment, quality assessment, refinement, and publication of knowledge graphs. We provide an overview of prominent open knowledge graphs and enterprise knowledge graphs, their applications, and how they use the aforementioned techniques. We conclude with high-level future research directions for knowledge graphs.", "language" : "English", "eprint" : "2003.02320", "bibsource" : "dblp computer science bibliography, https://dblp.org", "archiveprefix" : "arXiv", "bibtexKey": "journals/corr/abs-2003-02320" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2f7dbf0a622ff3e694c009ec93060c47f/lschmelzeisen", "tags" : [ "@AnalyticComp","AnalyticComputing","dblp","myown" ], "intraHash" : "f7dbf0a622ff3e694c009ec93060c47f", "interHash" : "61c25eacd5f7a0ba141e22543fe91a8e", "label" : "Learning Taxonomies of Concepts and not Words using Contextualized Word Representations: A Position Paper.", "user" : "lschmelzeisen", "description" : "", "date" : "2020-11-26 10:09:22", "changeDate" : "2020-11-26 09:23:09", "count" : 3, "pub-type": "article", "journal": "CoRR", "year": "2019", "url": "https://arxiv.org/abs/1902.02169", "author": [ "Lukas Schmelzeisen","Steffen Staab" ], "authors": [ {"first" : "Lukas", "last" : "Schmelzeisen"}, {"first" : "Steffen", "last" : "Staab"} ], "volume": "abs/1902.02169","abstract": "Taxonomies are semantic hierarchies of concepts.
