Before revision: The Semantic Web is an interoperable ecosystem where data producers, such as libraries, public institutions, communities, and companies, publish and link heterogeneous resources. To support this heterogeneity, its format, RDF, allows to describe collections of items sharing some attributes but not necessarily all of them. This flexible framework leads to incompleteness and inconsistencies in information representation, which in turn leads to unreliable query results. In order to make their data reliable and usable, Linked Data producers need to provide the best level of completeness .
After revision: Knowledge Graphs (KG) are incomplete by design; they allow to merge and connect heterogeneous data despite their differences. Nevertheless, KG data producers need to provide the best level of completeness .
