cc.mallet.pipe
Class SGML2TokenSequence

java.lang.Object
  cc.mallet.pipe.Pipe
      cc.mallet.pipe.SGML2TokenSequence

All Implemented Interfaces:

AlphabetCarrying, java.io.Serializable

public class SGML2TokenSequence
extends Pipe
implements java.io.Serializable

Converts a string containing simple SGML tags into a dta TokenSequence of words, paired with a target TokenSequence containing the SGML tags in effect for each word. It does not handle nested SGML tags, nor gracefully handle malformed SGML.
