parentCustomEntity()

parentCustomEntity() -> { wink-nlp custom entity }

This method returns the parent custom entity (if any) of a token item, as only a token may have a parent custom entity. If there is no parent custom entity, it returns undefined.

The custom entity is returned in a winkNLP format and can either be chained with other winkNLP methods or it can be followed by out() to get the entity as a string.

Example:

const text = 'The Godfather premiered on March 15, 1972. It was released on March 24, 1972.';
const patterns = [
  { name: 'event', patterns: [ '[VERB] [|ADP] [DATE|DURATION]' ] }
];
nlp.learnCustomEntities( patterns );
const doc = nlp.readDoc( text );

const token = doc.tokens().itemAt( 11 ); // -> released
const parentCustomEntity = token.parentCustomEntity();
console.log( `Token: ${ token.out() }, Parent custom entity: "${ parentCustomEntity.out() }"` );
// -> Token: released, Parent custom entity: "released on March 24, 1972"
