getPathsToCommonAncestor

public static List<LinkedList<ConllDependencyNode>> getPathsToCommonAncestor(ConllDependencyNode node1,
                                                                             ConllDependencyNode node2)

Returns the paths from each node to the common ancestor between them

getCommonAncestor

public static ConllDependencyNode getCommonAncestor(ConllDependencyNode node1,
                                                    ConllDependencyNode node2)

Returns the common ancestor between them

findAnnotationHead

public static ConllDependencyNode findAnnotationHead(org.apache.uima.jcas.JCas jcas,
                                                     org.apache.uima.jcas.tcas.Annotation annotation)

Finds the head word within a given annotation span

getPathToSentenceHead

public static LinkedList<ConllDependencyNode> getPathToSentenceHead(ConllDependencyNode node)

getPathBetweenNodes

public static LinkedList<ConllDependencyNode> getPathBetweenNodes(ConllDependencyNode srcNode,
                                                                  ConllDependencyNode tgtNode)
