示例1: demoDP
import edu.stanford.nlp.trees.Tree; //导入方法依赖的package包/类
/**
* demoDP demonstrates turning a file into tokens and then parse trees. Note
* that the trees are printed by calling pennPrint on the Tree object. It is
* also possible to pass a PrintWriter to pennPrint if you want to capture
* the output.
*
* file => tokens => parse trees
*/
public static void demoDP(LexicalizedParser lp, String filename) {
// This option shows loading, sentence-segmenting and tokenizing
// a file using DocumentPreprocessor.
TreebankLanguagePack tlp = new PennTreebankLanguagePack();
GrammaticalStructureFactory gsf = tlp.grammaticalStructureFactory();
// You could also create a tokenizer here (as below) and pass it
// to DocumentPreprocessor
for (List<HasWord> sentence : new DocumentPreprocessor(filename)) {
Tree parse = lp.apply(sentence);

System.out.println();
GrammaticalStructure gs = gsf.newGrammaticalStructure(parse);

示例2: demoAPI
import edu.stanford.nlp.trees.Tree; //导入方法依赖的package包/类
/**
* demoAPI demonstrates other ways of calling the parser with already
* tokenized text, or in some cases, raw text that needs to be tokenized as
* a single sentence. Output is handled with a TreePrint object. Note that
* the options used when creating the TreePrint can determine what results
* to print out. Once again, one can capture the output by passing a
* PrintWriter to TreePrint.printTree.
*
* difference： already tokenized text
