All Implemented Interfaces:

TreeFactory

public class LabeledScoredTreeFactory

extends SimpleTreeFactory

A LabeledScoredTreeFactory acts as a factory for creating trees with labels and scores. Unless another LabelFactory is supplied, it will use a StringLabel by default.

Constructor Summary

LabeledScoredTreeFactory()
Make a TreeFactory that uses LabeledScoredTree trees, where the labels are of class StringLabel

LabeledScoredTreeFactory(LabelFactory lf)
Make a treefactory that uses LabeledScoredTree trees, where the labels are as specified by the user.

Method Summary

Tree	newLeaf(Label label) Create a new leaf node with the given label
Tree	newLeaf(String word) Create a new tree leaf node, where the label is formed from the String passed in.
Tree	newTreeNode(Label parentLabel, List children) Create a new non-leaf tree node with the given label
Tree	newTreeNode(String parent, List children) Create a new tree nonleaf node, where the label is formed from the String passed in.
