CaLiGraph - A Large-Scale Semantic Knowledge Graph compiled from Wikipedia Categories and List Pages

Heist, Nicolas; Paulheim, Heiko

CaLiGraph is a large-scale semantic knowledge graph with a rich ontology which is compiled from the DBpedia ontology, and Wikipedia categories & list pages. For more information, visit http://caligraph.org

Information about uploaded files:
(all files are b-zipped and in the n-triple format)

caligraph-metadata.nt.bz2
Metadata about the dataset which is described using void vocabulary.

caligraph-ontology.nt.bz2
Class definitions, property definitions, restrictions, and labels of the CaLiGraph ontology.

caligraph-ontology_dbpedia-mapping.nt.bz2
Mapping of classes and properties to the DBpedia ontology.

caligraph-ontology_provenance.nt.bz2
Provenance information about classes (i.e. which Wikipedia category or list page has been used to create this class).

caligraph-instances_types.nt.bz2
Definition of instances and (non-transitive) types.

caligraph-instances_transitive-types.nt.bz2
Transitive types for instances (can also be induced by a reasoner).

caligraph-instances_labels.nt.bz2
Labels for instances.

caligraph-instances_relations.nt.bz2
Relations between instances derived from the class restrictions of the ontology (can also be induced by a reasoner).

caligraph-instances_dbpedia-mapping.nt.bz2
Mapping of instances to respective DBpedia instances.

caligraph-instances_provenance.nt.bz2
Provenance information about instances (e.g. if the instance has been extracted from a Wikipedia list page).

dbpedia_caligraph-instances.nt.bz2
Additional instances of CaLiGraph that are not in DBpedia.
! This file is no part of CaLiGraph but should rather be used as an extension to DBpedia. The triples use the DBpedia namespace and can thus be used to directly extend DBpedia. !

dbpedia_caligraph-types.nt.bz2

Changelog

v2.1.0

  • Fixed error that lead to a class inheriting from a disjoint class
  • Introduced owl:ObjectProperty and owl:DataProperty instead of rdf:Property
  • Several cosmetic fixes

v2.0.2

  • Fixed incorrect formatting of some properties

v2.0.1

  • Better entity extraction and representation
  • Small cosmetic fixes

v2.0.0

  • Entity extraction from arbitrary tables and enumerations in Wikipedia pages

v1.4.0

  • BERT-based recognition of subject entities and improved language models from spaCy 3.0

v1.3.1

  • Fixed minor encoding errors and improved formatting

v1.3.0

  • CaLiGraph is now based on a recent version of Wikipedia and DBpedia from November 2020

v1.1.0

  • Improved the CaLiGraph type hierarchy
  • Many small bugfixes and improvements

v1.0.9

  • Additional alternative labels for CaLiGraph instances

v1.0.8

  • Small cosmetic changes to URIs to be closer to DBpedia URIs

v1.0.7

  • Mappings from CaLiGraph classes to DBpedia classes are now realised via rdfs:subClassOf instead of owl:equivalentClass
  • Entities are now URL-encoded to improve accessibility

v1.0.6

  • Fixed a bug in the ontology creation step that led to a substantially lower amount of sub-type relationships than actually exist. The new version provides a richer type hierarchy that also leads to an increased amount of types for resources.

v1.0.5

  • Fixed a bug that has declared CaLiGraph predicates as subclasses of owl:Predicate instead of being of the type owl:Predicate.
