Examples of edu.stanford.nlp.trees.Tree.label()

edu.stanford.nlp.trees.Tree.label()
Returns the label associated with the current node, or null if there is no label. The default implementation always returns {@code null}. @return The label of the node

    // TODO: I don't have an explanation for this, it was just stated
    // in Zhang & Clark 2009
    if (state.stack.size() > 0) {

      // Temporary node, eg part of a binarized sequence

          ShiftReduceUtils.getBinarySide(top) == BinaryTransition.Side.RIGHT) {
