这是我的代码：

import java.util.*;

import edu.stanford.nlp.pipeline.Annotation;

import edu.stanford.nlp.pipeline.StanfordCoreNLPClient;

public class tagger {

public static void test(){

// creates a StanfordCoreNLP object with POS tagging, lemmatization, NER, parsing, and coreference resolution

Properties props = new Properties();

props.setProperty("annotators", "tokenize, ssplit, pos, lemma, ner, parse, dcoref");

StanfordCoreNLPClient pipeline = new StanfordCoreNLPClient(props, "localhost", 9000, 2);

// read some text in the text variable

String text = "How are you today?";

// create an empty Annotation just with the given text

Annotation document = new Annotation(text);

// run all Annotators on this text

pipeline.annotate(document);

}

public static void main(String[] args){

test();

}

}
