Class ChineseSegmenterAnnotator

java.lang.Object
  edu.stanford.nlp.pipeline.ChineseSegmenterAnnotator

All Implemented Interfaces:

Annotator

public class ChineseSegmenterAnnotator
extends java.lang.Object
implements Annotator

This class will add Segmentation information to an Annotation. It assumes that the original String or List is under the Annotation.ORIG_STRING_KEY and also corresponding character level information is under Annotation.WORDS_KEY and addes segmentation information to each CoreLabel, in the CoreLabel.CH_SEG_KEY field.

public void annotate(Annotation annotation)

Description copied from interface: Annotator

Given an annotation, perform a task on this annotaiton.

Specified by:

annotate in interface Annotator

doOneSentence

public void doOneSentence(CoreMap annotation)

splitCharacters
