Constructor Detail

Node

public Node(int id,
            int parent,
            String pos,
            String morph,
            String edge)

Create a non-leaf node.

Parameters:

id - The node’s ID.

parent - The parent ID of the node.

pos - The part of speech tag of the node.

morph - The morphology tag of the node.

edge - The label of the edge to the node.

Node

public Node(int id,
            int parent,
            String pos,
            String morph,
            String edge,
            String lemma,
            String word)

Create a leaf node.

Parameters:

id - The node’s ID.

parent - The parent ID of the node.

pos - The part of speech tag of the node.

morph - The morphology tag of the node.

edge - The label of the edge to the node.

lemma - The lemma form of the word.

word - The word in the string corresponding to this node.

Method Detail

getId

public int getId()

Get the ID of this tree in the tree bank.

Returns:

The ID

getParentId

public int getParentId()

Get the ID of the parent in the tree.

Returns:

The ID of the parent of this node.

getPos

public String getPos()

Get the Part-Of-Speech tag.

Returns:

The part-of-speech tag.

getMorph

public String getMorph()

getEdgeLabel

public String getEdgeLabel()

getLemma

public String getLemma()

Get the lemma tag.

Returns:

The lemma tag.

getWord

public String getWord()

getLeftCorner

public int getLeftCorner()

getRightCorner

public int getRightCorner()

getDaughters

public LinkedList<Node> getDaughters()

insertDaughter

public void insertDaughter(Node node)

toBinaryTree

public BinaryTree.BinaryNode toBinaryTree(List<Node> sisters,
                                          int sisterIndex)

Convert to binary tree and collect label. We follow the leftmost-daughter next-sister encoding.

Parameters:

sisters - The sisters of the current node.

sisterIndex - The index of the sister in the sister list that should be processed next.

Returns:

A binary node that corresponds to this node in its binary form.

toString

public String toString()

Overrides:

toString in class Object
