findAnnotationValues

private static java.util.List<java.lang.String> findAnnotationValues(java.lang.String annotationName,
                                                                     java.lang.String... annotations)

Find annotation values

Parameters:

annotationName - annotation name

annotations - annotation source strings

Returns:

list of values

makeNodeAnnotations

public static java.util.Map<java.lang.String,java.lang.String> makeNodeAnnotations(java.lang.String... annotations)

Extract node annotations

Parameters:

annotations - annotation source string

Returns:

node-indexed annotation strings

makeAllAnnotations

static java.lang.String[] makeAllAnnotations(java.lang.String... annotations)

Extract all annotations

Parameters:

annotations - annotation source strings

Returns:

list of annotation strings

makeWordAnnotations

private static java.lang.String[] makeWordAnnotations(java.lang.String... annotations)

Extract words

Parameters:

annotations - annotation source string

Returns:

list of words

makeTokens

private static java.util.List<java.lang.String> makeTokens(java.lang.String... annotations)

Make tokens

Parameters:

annotations - annotation string

Returns:

list of string tokens

makePoses

private static java.util.List<java.lang.String> makePoses(java.lang.String... annotations)

Make parts-of-speech

Parameters:

annotations - annotation string

Returns:

list of parts-of-speech tags

makeProjectiveDependencies

public static java.util.List<edu.stanford.nlp.trees.TypedDependency> makeProjectiveDependencies(java.lang.String str)

Make projective dependencies

Parameters:

Returns:

typed dependencies

indexLeaves

private static int indexLeaves(edu.stanford.nlp.trees.Tree node,
                               int startIndex0,
                               java.util.Map<edu.stanford.nlp.trees.Tree,java.lang.Integer> indices)

Helper (private function) Assign sequential integer indices to the leaves of the subtree rooted at this Tree, beginning with startIndex, and traversing the leaves from left to right. If node is already indexed, then it uses the existing index.

Parameters:

node - node

startIndex0 - index for this node

indices - index map

Returns:

the next index still unassigned

indexNodes

private static int indexNodes(edu.stanford.nlp.trees.Tree node,
                              int startIndex0,
                              java.util.Map<edu.stanford.nlp.trees.Tree,java.lang.Integer> indices)

Assign sequential integer indices to all nodes of the subtree rooted at this TreeGraphNode, beginning with startIndex, and doing a pre-order tree traversal. Any node which already has an index will not be re-indexed — this is so that we can index the leaves first, and then index the rest.

Parameters:

node - node

startIndex0 - index for this node

indices - index map

Returns:

the next index still unassigned

indexNodes

public static void indexNodes(edu.stanford.nlp.trees.Tree node,
                              java.util.Map<edu.stanford.nlp.trees.Tree,java.lang.Integer> indices)

Assign sequential integer indices (starting with 0) to all nodes of the subtree rooted at this TreeGraphNode. The leaves are indexed first, from left to right. Then the internal nodes are indexed, using a pre-order tree traversal.

Parameters:

node - node

indices - index map

indexLeaves

private static int indexLeaves(edu.stanford.nlp.trees.TreeGraphNode node,
                               int startIndex0)

Helper (private function) Assign sequential integer indices to the leaves of the subtree rooted at this TreeGraphNode, beginning with startIndex, and traversing the leaves from left to right. If node is already indexed, then it uses the existing index.

Parameters:

node - node

startIndex0 - index for this node

Returns:

the next index still unassigned

indexNodes

public static void indexNodes(edu.stanford.nlp.trees.TreeGraphNode node)

Assign sequential integer indices (starting with 0) to all nodes of the subtree rooted at this TreeGraphNode. The leaves are indexed first, from left to right. Then the internal nodes are indexed, using a pre-order tree traversal.

Parameters:

node - node

indexNodes

private static int indexNodes(edu.stanford.nlp.trees.TreeGraphNode node,
                              int startIndex0)

Assign sequential integer indices to all nodes of the subtree rooted at this TreeGraphNode, beginning with startIndex, and doing a pre-order tree traversal. Any node which already has an index will not be re-indexed — this is so that we can index the leaves first, and then index the rest.

Parameters:

node - node

startIndex0 - index for this node

Returns:

the next index still unassigned

stripAnnotations

public static java.lang.String stripAnnotations(java.lang.String annotationString)

Strip annotation string

Parameters:

annotationString - annotation string

Returns:

string without annotation

nameValuesToString

static java.lang.String nameValuesToString(java.lang.String[][] nameValues)

Array of name values to String

Parameters:

nameValues - name-value array

Returns:

string
