tkgl_wikidata — Wikidata temporal knowledge graph (tkgl-wikidata, TGB 2.0)

Description

A temporal knowledge graph extracted from Wikidata, from the tkgl-wikidata dataset of the Temporal Graph Benchmark (TGB 2.0), a superset of tkgl_smallpedia: the statements of the Wikidata entities with identifiers below 32 million (i.e. Q1 to Q31999999), and the entities they point to. Each node is an entity of Wikidata, and a directed edge from entity A to entity B is a statement (A, relation, B), with a Wikidata property as relation (e.g. P39, "position held", or P166, "award received"). Pairs of entities may be connected by several edges.

temporal: the statements with a time (a point in time, or the start of a period), as a year from 0 to 2024 (9,856,203 edges).
static: the statements of the same entities without a time (71,900,685 edges); the statements that are also temporal ones were removed by TGB.

The data do not include the labels of the entities and relations, which can be looked up in Wikidata. The negative samples of the benchmark (statements that do not exist, used for evaluation) are left out.

The networks have the following properties:

(Node) wikidata_id: the Wikidata identifier of the entity, e.g. Q31.
(Edge) relation: the Wikidata property of the statement, e.g. P166.
(Edge) year (temporal only): the year of the statement.
