dbpedia_occupation — Person-Occupation Affiliations (DBpedia, 2013)

Description

A bipartite network of persons and their occupations. The data are from version 3.9 of DBpedia, which extracts structured information from the infoboxes of Wikipedia articles and maps it onto the DBpedia ontology; this release was extracted from the English Wikipedia dumps of late March / early April 2013, and was published in September 2013. Each edge is one triple of the dbo:occupation relation in the "Mapping-based Properties (Cleaned)" dataset of the release, from which the statements identified as incorrect by heuristic inference were removed. Nodes are persons and occupations, and each edge connects a person (and, in a few cases, a fictional character, band or other entity) to an occupation listed in their infobox. When the occupation field of the infobox is plain text rather than a link, DBpedia creates an intermediate node for it (named after the person, e.g. Peter_Falk__1, with type PersonFunction), with the text in its title; most occupation nodes are of this kind, and have degree one.

A resource that appears on both sides of the relation is represented by two distinct nodes, one on each side, and repeated triples are included only once. Objects of the relation 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: the name of the DBpedia resource, i.e. the title of the corresponding English Wikipedia article (with underscores instead of spaces), with the percent-encoding of the URI decoded.
(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).
(Node) title: the occupation text, for the intermediate PersonFunction nodes (several values are separated by ;; empty for other nodes).
(Node) is_occupation: whether the node is an occupation (otherwise it is a person).
