如何在 Java 中获得等效的 Stanford-Core-nlp Python 输出

Question

我在 Python 中有一个这样的函数-

nlp = StanfordCoreNLP(host + ":" + port)
text = "Joshua Brown, 40, was killed in Florida in May when his Tesla failed to " \
       "differentiate between the side of a turning truck and the sky while " \
       "operating in autopilot mode."
output = nlp.annotate(
    text,
    properties={
        "outputFormat": "json",
        "annotators": "depparse,ner,entitymentions,sentiment"
    }
)
pprint(output)

它得到这样的输出 -

{
  'sentences': [
    {
      'basicDependencies': [
        {
          'dep': 'ROOT',
          'dependent': 7,
          'dependentGloss': 'killed',
          'governor': 0,
          'governorGloss': 'ROOT'
        },
        {
          'dep': 'compound',
          'dependent': 1,
          'dependentGloss': 'Joshua',
          'governor': 2,
          'governorGloss': 'Brown'
        },
        …
      ],
      'enhancedDependencies': [
        {
          'dep': 'ROOT',
          'dependent': 7,
          'dependentGloss': 'killed',
          'governor': 0,
          'governorGloss': 'ROOT'
        },
        {
          'dep': 'compound',
          'dependent': 1,
          'dependentGloss': 'Joshua',
          'governor': 2,
          'governorGloss': 'Brown'
        },

但我想在 Java 中做同样的事情，所以我写了一个 java 方法，比如 -

public class NlpTest implements RequestHandler<Input,Output>{
    public static String text = "Multiple locations in Maharashtra linked to state transport minister Anil Parab were raided this morning by the Enforcement Directorate (ED) as part of a money-laundering probe relating to alleged irregularities in a land deal.";


    @Override
    public Output handleRequest(Input input, Context context) {


        String output="";
        try {
            System.out.println("entering method handleRequest");
            System.out.println("text = " + text);

            Properties props = new Properties();
            //props.setProperty("annotators", "tokenize, ssplit, pos, lemma, ner, parse, dcoref, tokensregex, sentiment");           //------>here
            props.setProperty("annotators", "depparse,ner,entitymentions,sentiment");
            props.setProperty("ner.additional.tokensregex.rules","src/main/java/custom.rules");

//            props.setProperty("coref.algorithm", "neural");
            props.setProperty("ner.useSUTime", "false");
            props.setProperty("outputFormat", "json");



            StanfordCoreNLP pipeline = new StanfordCoreNLP(props);


            CoreDocument doc = new CoreDocument(text);
            // annotate
            pipeline.annotate(doc);
            System.out.println("pipeline="+pipeline.toString());
            System.out.println("doc.entityMentions() = " + doc.entityMentions());
            // display tokens
            for (CoreLabel tok : doc.tokens()) {
                System.out.println(String.format("%s\t%d\t%d", tok.word(), tok.beginPosition(), tok.endPosition()));
            }

我将单个字段作为输出，但我想获得从 Python 方法获得的直接 JSON 输出。我的问题是如何在 Java 中执行此操作。 无论我在 Python 中做什么，如何在 Java 中做到这一点？ 我是 Stanford-core-NLP 的新手，非常感谢任何帮助。 谢谢！

您似乎已经熟悉 Java。 将您指向edu.stanford.nlp.pipeline.JSONOutputter就足够了，还是您需要更多？
