Class MultiWordTreeExpander

java.lang.Object

edu.stanford.nlp.international.spanish.pipeline.MultiWordTreeExpander

public class MultiWordTreeExpander
extends java.lang.Object

Provides routines for "decompressing" further the expanded trees formed by multiword token splitting. Multiword token expansion leaves constituent words as siblings in a "flat" tree structure. This often represents an incorrect parse of the sentence. For example, the phrase "Ministerio de Finanzas" should not be parsed as a flat structure like (grup.nom (np00000 Ministerio) (sp000 de) (np00000 Finanzas)) but rather a "deep" structure like (grup.nom (sp (prep (sp000 de)) (sn (grup.nom (np0000 Finanzas))))) This class provides methods for detecting common linguistic patterns that should be expanded in this way.
