Class ParserAnnotator

java.lang.Object

edu.stanford.nlp.pipeline.SentenceAnnotator

edu.stanford.nlp.pipeline.ParserAnnotator

All Implemented Interfaces:

Annotator

public class ParserAnnotator
extends SentenceAnnotator

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).

doOneFailedSentence

public void doOneFailedSentence(Annotation annotation,
                       CoreMap sentence)

Description copied from class: SentenceAnnotator

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".

requirementsSatisfied

public Set<Annotator.Requirement> requirementsSatisfied()

Description copied from interface: Annotator

Returns a set of requirements for which tasks this annotator can provide. For example, the POS annotator will return "pos".
