Class ParserAnnotator

java.lang.Object

edu.stanford.nlp.pipeline.ParserAnnotator

All Implemented Interfaces:

Annotator

public class ParserAnnotator
extends Object
implements Annotator

This class will add parse information to an Annotation. It assumes that the Annotation already contains the tokenized words as a List<CoreLabel> in the TokensAnnotation under each particular CoreMap in the SentencesAnnotation. If the words have POS tags, they will be used.
Parse trees are added to each sentence's CoreMap (get with CoreAnnotations.SentencesAnnotation) under CoreAnnotations.TreeAnnotation).

annotate

public void annotate(Annotation annotation)

Description copied from interface: Annotator

Given an Annotation, perform a task on this Annotation.

Specified by:

annotate in interface Annotator

requires

public Set<Annotator.Requirement> requires()

Description copied from interface: Annotator

Returns the set of tasks which this annotator requires in order to perform. For example, the POS annotator will return "tokenize", "ssplit".

Specified by:

requires in interface Annotator

requirementsSatisfied
