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).

protected long maxTime()

Description copied from class: SentenceAnnotator

The maximum time to run this annotator for, in milliseconds.

Specified by:

maxTime in class SentenceAnnotator

doOneSentence

protected void doOneSentence(Annotation annotation,
                             CoreMap sentence)

Description copied from class: SentenceAnnotator

annotation is included in case there is global information we care about

Specified by:

doOneSentence in class SentenceAnnotator

doOneFailedSentence

public void doOneFailedSentence(Annotation annotation,
                                CoreMap sentence)

Description copied from class: SentenceAnnotator

Fills in empty annotations for trees, tags, etc if the annotator failed or timed out. Not supposed to do major processing.

Specified by:

doOneFailedSentence in class SentenceAnnotator

Parameters:

annotation - The whole Annotation object, in case it is needed for context.

sentence - The particular sentence to process

requires

public java.util.Set<java.lang.Class<? extends CoreAnnotation>> 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 java.util.Set<java.lang.Class<? extends CoreAnnotation>> 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".
