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

edu.stanford.nlp.trees.Tree.preTerminalYield()
Gets the preterminal yield (i.e., tags) of the tree. All data in preterminal nodes is returned as a list ordered by the natural left to right order of the tree. Null values, if any, are inserted into the list like any other value. Pre-leaves are nodes of height 1. @return a {@code List} of the data in the tree's pre-leaves.

    while (treeItr.hasNext()) {
      Tree tree = treeItr.next();
      // CoreLabels, with morph analysis in the originalText annotation
      List<Label> yield = rawTrees == null ? tree.yield() : rawTreesItr.next().yield();
      // Annotated, binarized tree for the tags (labels are usually CategoryWordTag)
      List<Label> pretermYield = tree.preTerminalYield();


      int yieldLen = yield.size();
      for (int i = 0; i < yieldLen; ++i) {
        String word = yield.get(i).value();
        int wordId = wordIndex.addToIndex(word); // Don't do anything with words
