Named entity recognition

Named entity recognition is a type of document analysis.
It determines which entities—persons, places, organizations, dates, addresses, etc.—are mentioned in a text and the attributes of the entity that can be inferred by semantic analysis.

Named entity recognition also performs knowledge linking: Knowledge Graph information and open data—Wikidata, DBpedia and GeoNames references—are returned for entities corresponding to syncons of the expert.ai Knowledge Graph. In the case of actual places, geographic coordinates are also provided.

Entities are also recognized in pronouns and shorter forms that refer to named mentions.
This kind of by reference recognition is anaphoric because entities are recognized through anaphoras.

For example in this text:

Michael Jordan was one of the best basketball players of all time.

Scoring was Jordan's stand-out skill, but he still holds a defensive NBA record, with eight steals in a half.

three mentions of Michael Jordan are recognized:

  • the full named mention: Michael Jordan
  • the anaphoras—Jordan and he—for which Michael Jordan is considered the antecedent.

The API resource carrying out named entity recognition has the following endpoint:
