Enclosing class:

CKYItem

public static class CKYItem.KBestHack
extends CKYItem.MappedPrevModBaseNPAware

A hack to approximate k-best parsing by effectively turning off dynamic programming (usability depends on reducing the beam size from its normal value). Two KBestHack chart items are only equal if they are object-equal.
