public static class CoreAnnotations.StackedNamedEntityTagAnnotation
extends java.lang.Object
implements CoreAnnotation<java.lang.String>
The CoreMap key for getting the token-level named entity tag (e.g., DATE,
PERSON, etc.) from a previous NER tagger. NERFeatureFactory is sensitive to
this tag and will turn the annotations from the previous NER tagger into
new features. This is currently used to implement one level of stacking --
we may later change it to take a list as needed.
This key is typically set on token annotations.
