Enclosing class:

Recommended

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

An extraction-oriented feature extractor to apply to multi-token spans. By default this extracts features for: the lower-case version of the phrase inside that span; lexical properties of the phrase; the length of the span; features for tokens in a small window to either side of the phrase, analogous to those extracted by TokenFE; features for the first and last tokens of the phrase, analogous to those extracted by TokenFE.

getCLP

public CommandLineProcessor getCLP()

Description copied from interface: CommandLineProcessor.Configurable

Produce a command-line processor that configures this object.

Specified by:

getCLP in interface CommandLineProcessor.Configurable
