Class QPTreeTransformer

java.lang.Object

edu.stanford.nlp.trees.QPTreeTransformer

All Implemented Interfaces:

TreeTransformer, java.util.function.Function<Tree,Tree>

public class QPTreeTransformer
extends java.lang.Object
implements TreeTransformer

Transforms an English structure parse tree in order to get the dependencies right: Adds an extra structure in QP phrases:
(QP (RB well) (IN over) (CD 9)) becomes
(QP (XS (RB well) (IN over)) (CD 9))
(QP (...) (CC ...) (...)) becomes
(QP (NP ...) (CC ...) (NP ...))

Method Detail

transformTree

public Tree transformTree(Tree t)

Right now (Jan 2013) we only deal with the following QP structures:

• NP (QP ...) (QP (CC and/or) ...)
• QP (RB IN CD|DT ...) well over, more than
• QP (JJR IN CD|DT ...) fewer than
• QP (IN JJS CD|DT ...) at least
• QP (... CC ...) between 5 and 10

Specified by:

transformTree in interface TreeTransformer

Parameters:

t - tree to be transformed

Returns:

The tree t with an extra layer if there was a QP structure matching the ones mentioned above

QPtransform

public Tree QPtransform(Tree t)

Transforms t if it contains one of the following QP structure:

• NP (QP ...) (QP (CC and/or) ...)
• QP (RB IN CD|DT ...) well over, more than
• QP (JJR IN CD|DT ...) fewer than
• QP (IN JJS CD|DT ...) at least
• QP (... CC ...) between 5 and 10

Parameters:

t - a tree to be transformed

Returns:

t transformed
