Package edu.stanford.nlp.pipeline

Class QuantifiableEntityNormalizingAnnotator

java.lang.Object

edu.stanford.nlp.pipeline.QuantifiableEntityNormalizingAnnotator

All Implemented Interfaces:

Annotator

public class QuantifiableEntityNormalizingAnnotator
extends Object
implements Annotator

This class provides a facility for normalizing content of numerical named entities (number, money, date, time) in the pipeline package world. It uses a lot of code with QuantifiableEntityNormalizer. New stuff should generally be added there so as to reduce code duplication.

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
