The safest way to be perceived as an entity is an entry on Wikipedia, Wikidata or submission to Google itself. More on this in the interesting self-experiment by our colleague Artur Kosch .
But Google reserves the right to check the entries and delete them from the databases if you do not provide enough referencing sources in the Wikidata entry. To prevent manipulation, an entry must be verified by at least one third source. Or so it seems. A Wikipedia page or Wikimedia entry seems to be an important source here.
While in Wikidata attributes of an entity are assigned in a rather romania phone number data bullet point manner, Wikipedia describes the entity in a detailed text. A Wikipedia article is therefore the detailed description of an entity and, as an external document, represents an important source for the Knowledge Graph.
For example, a unique identification reference may be stored within the node, a short information string may be stored in a terminal node as a literal, and a long description of an entity may be stored in an external document linked to by a reference in the knowledge graph.
In a scientific project in which a Google employee was also involved, an entity is equated with a Wikipedia article.
“ An entity (or concept , topic ) is a Wikipedia article which is uniquely identified by its page-ID .”
Wikipedia articles play a major role as a source of information in many Knowledge Graph boxes and are used by Google alongside Wikidata entries as proof of the relevance of an entity. Without an entry in Wikipedia or Wikidata, there is no entity box or knowledge panel.
However, most companies and people are denied an entry on Wikipedia because they lack social relevance in the eyes of Wikipedians. You can find out whether your company or you yourself are relevant enough for Wikipedia in the article Is my company relevant for Wikipedia? or our detailed guide to communication on Wikipedia .
A sensible alternative is to set up a profile on Wikidata . The frequency of recurring consistent data across different trusted sources makes it easier for Google to clearly identify entities.
