1Virtual Knowledge Graphs:An Overview of Systems and Use Cases显示文摘In this paper,we present the virtual knowledge graph(VKG)paradigm for data integration and access,also known in the literature as Ontology-based Data Access.Instead of structuring the integration layer as a collection of relational tables,the VKG paradigm replaces the rigid structure of tables with the flexibility of graphs that are kept virtual and embed domain knowledge.We explain the main notions of this paradigm,its tooling ecosystem and significant use cases in a wide range of applications.Finally,we discuss future research directions.Guohui Xiao Linfang Ding Benjamin Cogrel Diego Calvanese 2019Data Intelligence2019,1,3:3
