COVID-19 Knowledge Graph:

• CoronaVirus Tracking, using Knowledge Graph generated from CSV

• Using Data from Our World In Data, Kingsley Idehen was able to build a Knowledge Graph comprising links to both DBpedia and Wikidata that offers a powerful conduit to a LOD Cloud rich in Linked Data covering BioInformatics, Genomics, Molecular Biology, Biology, Chemistry etc.

• Our World In Data is also adopting the “best practice” of publishing COVID19 in Open Data form. This enables change-sensitive Google Spreadsheet population using the ImportData() function.

• Once you have Open Data in a Google Spreadsheet, you can use a SPARQL-FED query (via our URIBurner service) that leverages the power of Linked Data for looking-up geo coordinates from DBpedia and Wikidata.

• The LOD Cloud is a major Knowledge Graph for Linked Data associated with Healthcare & Life Sciences (HCLS). Here are links to SPARQL queries service endpoint collections to aid researchers at all levels.
