edu.umn.cs.nlp.mt.chiang2007.ChartCellEntry
public class ChartCellEntry
Represents a symbol that spans a portion of a parse chart.
The k-best extraction technique used in Huang & Chiang (2005) requires that a parse chart be viewed as a hypergraph. In that context, a ChartCellEntry serves as a vertex in a hypergraph.
