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

description: 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:<br> (all files are b-zipped and in the n-triple format)<br> <br> caligraph-metadata.nt.bz2<br> Metadata about the dataset which is described using void vocabulary. caligraph-ontology.nt.bz2<br> Class definitions, property definitions, restrictions, and labels of the CaLiGraph ontology. caligraph-ontology_dbpedia-mapping.nt.bz2<br> Mapping of classes and properties to the DBpedia ontology. caligraph-ontology_provenance.nt.bz2<br> Provenance information about classes (i.e. which Wikipedia category or list page has been used to create this class). caligraph-instances_types.nt.bz2<br> Definition of instances and (non-transitive) types. caligraph-instances_transitive-types.nt.bz2<br> Transitive types for instances (can also be induced by a reasoner). caligraph-instances_labels.nt.bz2<br> Labels for instances. caligraph-instances_relations.nt.bz2<br> Relations between instances derived from the class restrictions of the ontology (can also be induced by a reasoner). caligraph-instances_dbpedia-mapping.nt.bz2<br> Mapping of instances to respective DBpedia instances. caligraph-instances_provenance.nt.bz2<br> Provenance information about instances (e.g. if the instance has been extracted from a Wikipedia list page). dbpedia_caligraph-instances.nt.bz2<br> Additional instances of CaLiGraph that are not in DBpedia.<br> ! 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<br> Additional types of CaLiGraph that are not in DBpedia.<br> !

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. ! <strong>Changelog</strong> v3.0.0 Added functionality to group mentions of unknown entities into distinct entities 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.
