获取LABEL与构建InstanceList

String[] labels = new String[crf.getOutputAlphabet().size()];for (int i = 0; i < crf.getOutputAlphabet().size(); i++) {labels[i] = (String) crf.getOutputAlphabet().lookupObject(i);} 

public void testCRF() throws Exception {Pipe p = makeSpacePredictionPipe();InstanceList trainInstances = new InstanceList(p);trainInstances.addThruPipe(new LineGroupIterator(new FileReader("data/conll.train"), Pattern.compile("^//s*$"), true));// InstanceList[] lists = trainInstances.split(new// java.util.Random(678),// new double[] { 1.0, .1 });InstanceList testInstances = new InstanceList(p);testInstances.addThruPipe(new LineGroupIterator(new FileReader("data/conll.test"), Pattern.compile("^//s*$"), true));// run(lists[0], lists[1]);run(trainInstances, testInstances);}private Pipe makeSpacePredictionPipe() {Pipe p = new SerialPipes(new Pipe[] {new SimpleTaggerSentence2TokenSequence(),new TokenSequence2FeatureVectorSequence(), });return p;}
