java - 如何为 stanford corenlp 获取文本的 xml 输出

Question

我一直在阅读 API 和文档试图找到答案，但还没有接近解决问题。

我想获取一堆句子并将所有句子输出为 XML:

      <token id="1"> 
        <word>That</word> 
        <lemma>that</lemma> 
        <CharacterOffsetBegin>0</CharacterOffsetBegin> 
        <CharacterOffsetEnd>4</CharacterOffsetEnd> 
        <POS>DT</POS> 
        <NER>O</NER> 
      </token> 

我只是想出了如何解析树，但这对我想要构建的东西没有帮助。不管怎样，这是我现在使用的代码:

Properties props = new Properties();
props.put("annotators", "tokenize, ssplit, pos, lemma, ner, parse, dcoref");
StanfordCoreNLP pipeline = new StanfordCoreNLP(props);

// read some text in the text variable
String text = "We won the game."; // Add your text here!

// create an empty Annotation just with the given text
Annotation document = new Annotation(text);

// run all Annotators on this text
pipeline.annotate(document);

// these are all the sentences in this document
// a CoreMap is essentially a Map that uses class objects as keys and has values with custom types
List<CoreMap> sentences = document.get(SentencesAnnotation.class);

for(CoreMap sentence: sentences) {

  // this is the parse tree of the current sentence
  Tree tree = sentence.get(TreeAnnotation.class);

  // this is the Stanford dependency graph of the current sentence
  SemanticGraph dependencies = sentence.get(CollapsedCCProcessedDependenciesAnnotation.class);
}

我正在使用文档中的代码。

使用内置的 xmlPrint 更容易一些:

    Properties props = new Properties();
    props.put("annotators", "tokenize, ssplit, pos, lemma, ner, parse, dcoref");
    StanfordCoreNLP pipeline = new StanfordCoreNLP(props);
    Annotation document = new Annotation("Four score and seven years ago.");
    pipeline.annotate(document);
    FileOutputStream os = new FileOutputStream(new File("./target/", "nlp.xml"));
    pipeline.xmlPrint(document, os);
