Method Detail

normalizeWholeTree

public Tree normalizeWholeTree(Tree tree,
                      TreeFactory tf)

Description copied from class: BobChrisTreeNormalizer

Normalize a whole tree -- one can assume that this is the root. This implementation deletes empty elements (ones with nonterminal tag label '-NONE-') from the tree, and splices out unary A over A nodes. It does work for a null tree.

Overrides:

normalizeWholeTree in class BobChrisTreeNormalizer

Parameters:

tree - The tree to be normalized

tf - the TreeFactory to create new nodes (if needed)

Returns:

Tree the normalized tree

normalizeTerminal

public java.lang.String normalizeTerminal(java.lang.String word)

Description copied from class: BobChrisTreeNormalizer

Normalizes a leaf contents. This implementation interns the leaf.

Overrides:

normalizeTerminal in class BobChrisTreeNormalizer

Parameters:

word - The String that decorates the leaf

Returns:

The normalized form of this leaf String
