Publication

While it may not always be desirable to publish knowledge graphs (for example, those that offer a competitive advantage to a company [Noy et al., 2019]), it maybe desirable or even required to publish other knowledge graphs, such as those produced by volunteers [Lehmann et al., 2015, Mahdisoltani et al., 2015, Vrandecic and Krotzsch, 2014], by publicly-funded research [Callahan et al., 2013, Groth et al., 2014, The UniProt Consortium, 2014], or by governmental organizations [Hendler et al., 2012, Shadbolt and O’Hara, 2013]. Publishing refers to making the knowledge graph (or part thereof) accessible to the public, often on the Web. Knowledge graphs published as open data are called open knowledge graphs (discussed in Section 10.1).
