Direct Known Subclasses:

Recommended.MultitokenSpanFE

Enclosing class:

Recommended

public static class Recommended.TokenFE
extends Recommended.TokenPropUsingFE
implements CommandLineProcessor.Configurable, java.io.Serializable

An extraction-oriented feature extractor, which should be applied to one-token spans. By default this extracts features for: the lower-case version of the single word inside that span; lexical properties of the word; and analogous features for tokens in a small window to either side of the word.
