Constructor Detail

FrenchTreeNormalizer

public FrenchTreeNormalizer(boolean ccTagset)

Method Detail

normalizeTerminal

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

Description copied from class: BobChrisTreeNormalizer

Normalizes a leaf contents. This implementation interns the leaf.

Overrides:

normalizeTerminal in class BobChrisTreeNormalizer

Parameters:

terminal - The String that decorates the leaf

Returns:

The normalized form of this leaf String

normalizeNonterminal

public java.lang.String normalizeNonterminal(java.lang.String category)

Description copied from class: BobChrisTreeNormalizer

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

Overrides:

normalizeNonterminal in class BobChrisTreeNormalizer

Parameters:

category - The String that decorates this nonterminal node

Returns:

The normalized form of this nonterminal String

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 assumes that it is not given a null tree, but it may return one if there are no real words.

Overrides:

normalizeWholeTree in class BobChrisTreeNormalizer

Parameters:

tree - The tree to be normalized

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

Returns:

The normalized tree. May be null which means to not use this tree at all.
