CaLiGraph is a large semantic knowledge graph with a rich ontology compiled from the DBpedia ontology and Wikipedia categories & list pages. The ontology is enriched with fine-grained value restrictions on its classes that are learned through the Cat2Ax approach. A large amount of CaLiGraph's resources are extracted from Wikipedia list pages through a combination of the ontological information with machine learning methods.
