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.

Method Detail

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 java.util.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

public java.util.Set<Annotator.Requirement> requirementsSatisfied()

Description copied from interface: Annotator
