CaLiGraph v1.0 released

The first version of CaLiGraph, an extensive knowledge graph extracted from categories and list pages in Wikipedia, has been released.

CaLiGraph is a large semantic knowledge graph with a rich ontology compiled from the DBpedia ontology and Wikipedia Categories & Listpages. 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 Listpages by combining the ontological information with machine learning.

The current release of CaLiGraph contains 5.6 million instances, as well as 759k classes with 204k defining axioms.
