Wikidata:SPARQL query service/WDQS graph split/Rules

This page describes the criteria used by WDQS to determine in what subgraph a given entity belongs to.

Definition

• An entity is part of the scholarly graph if it declares either:
  • a non-deprecated publication type of scholarly work (P13046) statement
  • a direct and non-deprecated statement instance of (P31) with a value defined in #Scholarly Articles.
• An entity is part of the main graph if it is not considered a scholarly article.

Examples

• If an entity declares a single instance of (P31) with scholarly article (Q13442814) it is part of the scholarly graph
• If an entity declares one or more publication type of scholarly work (P13046) it is part of the scholarly graph (even if none of its instance of (P31) is an instance of #Scholarly Articles).
• If all instance of (P31) statements declared by an entity are not part of #Scholarly Articles it is part of the main graph
• If an entity declares multiple instance of (P31) with one of them part of #Scholarly Articles it is part of the scholarly graph
• If an entity declared a instance of (P31) that is a subclass of (P279) of #Scholarly Articles it is not necessarily part of the scholarly graph (it is only if one its P31 statement is a direct link to #Scholarly Articles)
• If an entity does not declare any instance of (P31) it is part of the main graph
• A Wikibase lexeme (Q51885771) is part of the main graph
• A Wikidata property (Q18616576) is part of the main graph

Known Issues

Entities having multiple instance of (P31) defined may pose some challenges. Please see Wikidata:Property proposal/publication type of scholarly article which hopefully might help to make these rules clearer in the future.
