Wikidata subset with revision history information [RDF]

This dataset is composed of 300 instances from the 100 most important classes in Wikidata, for a total of around 30000 entities and 390000 triples. The dataset is geared towards knowledge graph refinement models that leverage edit history information from the graph. There are two versions of the dataset:

The static version (files postfixed with '_static') contains the simple statements of each entity fetched from Wikidata.

The dynamic version (files postfixed with '_dynamic') contains information about the operations and revisions made to these entities, and the triples that were added or removed.

Each version is split into three subsets: train, validation (val), and test. Each split contains every entity from the dataset. The train split contains the first 70% of revisions made to each entity, the validation split contains the 70% to 85% revisions, and the test set contains the last 15% revisions.

This is a sample from the static datasets:

wd:Q217432 a uo:entity ;
wdt:P1082 1.005904e+06 ;
wdt:P1296 "0052280" ;
wdt:P1791 wd:Q18704103 ;
wdt:P18 "Pitakwa.jpg" ;
wdt:P244 "n80066826" ;
wdt:P571 "[phone]T00:00:00Z" ;
wdt:P6766 "421180027" .

Each entity has the type uo:entity, and contains the statements added during that time period following Wikidata's data model.

In the following code snippet we show an example from the dynamic dataset:

uo:rev703872813 a uo:revision ;
uo:timestamp "2018-06-28T22:31:32Z" .

uo:op703872813_0 a uo:operation ;
uo:fromRevision uo:rev703872813 ;
uo:newObject wd:Q82955 ;
uo:opType uo:add ;
uo:revProp wdt:P106 ;
uo:revSubject wd:Q6097419 .

uo:op703878666_0 a uo:operation ;
uo:fromRevision uo:rev703878666 ;
uo:opType uo:remove ;
uo:prevObject wd:Q1108445 ;
uo:revProp wdt:P460 ;
uo:revSubject wd:Q1147883 .

This dataset is composed of revisions, which have a timestamp. Each revision is composed of 1 to n operations, in which there is a change to a statement from the entity. There are two types of operations: uo:add and uo:remove. In both cases, the property and the subject being modified are shown with the uo:revProp and uo:revSubject properties. In the case of additions, uo:newObject and uo:prevObject properties are added to show the previous and new objects after the addition. In the case of removals, there is a uo:prevObject property to record the object that was removed.
