Class RegexNERAnnotator

java.lang.Object

edu.stanford.nlp.pipeline.RegexNERAnnotator

All Implemented Interfaces:

Annotator

public class RegexNERAnnotator
extends java.lang.Object
implements Annotator

This class adds NER information to an annotation using the RegexNERSequenceClassifier. It assumes that the Annotation has already been split into sentences, then tokenized into Lists of CoreLabels. Adds NER information to each CoreLabel as a NamedEntityTagAnnotation.
