KastorText2KG_V2

KastorKG is the distilled knowledge graph produced by the https://github.com/datalogism/Kastor pipeline. It is built from DBpedia by filtering    
  triples through SHACL shapes and verifying their grounding in Wikipedia abstracts (Wikicheck step). The KB is stored as a set of named graphs in  
  Apache Jena TDB, queryable via a Corese SPARQL endpoint.
