public String normalizeTerminal(String leaf)

Normalizes a leaf contents. This implementation interns the leaf.

Overrides:

normalizeTerminal in class TreeNormalizer

normalizeNonterminal

public String normalizeNonterminal(String category)

Normalizes a nonterminal contents. This implementation strips functional tags, etc. and interns the nonterminal.

Overrides:

normalizeNonterminal in class TreeNormalizer

normalizeWholeTree

public Tree normalizeWholeTree(Tree tree,
                               TreeFactory tf)

Description copied from class: TreeNormalizer

Normalize a whole tree -- this method assumes that the argument that it is passed is the root of a complete Tree. It is normally implemented as a Tree-walking routine.

Overrides:

normalizeWholeTree in class TreeNormalizer

Parameters:

tree - The tree to be normalized

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

Returns:

Tree the normalized tree
