dbpedia_all — DBpedia network (v3.9, 2013)
- Description
A directed network of the relations between the entities of DBpedia, a project that extracts structured information from Wikipedia. The data are from version 3.9 of DBpedia, which was extracted from the English Wikipedia dumps of late March / early April 2013 and published in September 2013. It contains every triple of the "Mapping-based Properties (Cleaned)" dataset of the release whose object is a resource rather than a literal value; this dataset holds the information of the Wikipedia infoboxes mapped onto the DBpedia ontology, from which the statements identified as incorrect by heuristic inference were removed. Nodes are resources (mostly entities with a Wikipedia article, such as people, places, organizations or works), and a directed edge $(i,j)$ is a triple stating that resource $i$ has a relation to resource $j$, e.g. that a person ($i$) was born in a place ($j$); repeated edges correspond to different relations between the same resources, and self-loops (7,665 triples) are kept. The relations are almost all properties of the DBpedia ontology (e.g.
dbo:birthPlace,dbo:team,dbo:genre), but also includerdf:typestatements pointing to the classgml:_Feature(for places with coordinates),skos:subject, and FOAF properties whose objects are web pages and images (e.g.foaf:homepage,foaf:depiction), which are nodes as well.Objects do not necessarily have an infobox, or even a Wikipedia article, of their own (e.g. when the infobox links to a missing article). Besides proper Wikipedia articles, some resources are intermediate nodes created by DBpedia for parts of an infobox, named after the article with a suffix
__<n>.The network has the following properties:
- (Node)
name: for DBpedia resources, the name of the resource, i.e. the title of the corresponding English Wikipedia article (with underscores instead of spaces), with the percent-encoding of the URI decoded; for other nodes, the full URI. - (Node)
type: the most specific class of the resource in the DBpedia ontology, from the "Mapping-based Types" dataset of the same release (empty if the resource has no type, e.g. because it has no infobox mapped to the ontology). - (Edge)
relation: the predicate of the triple, abbreviated with the prefixesdbo:(DBpedia ontology),rdf:,skos:andfoaf:.
