Question

我按照http://stanfordnlp.github.io/CoreNLP/corenlp-server.html中的教程设置我自己的stanford解析器服务器。但是，当我粘贴示例代码时，会出现错误：

Exception in thread "Thread-1" edu.stanford.nlp.io.RuntimeIOException: Could not connect to server: localhost:9000

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();
    }
}

您提供的代码对我来说没有改变。（它不会打印任何内容;在测试时，您可能会尝试在System.out.println(document.toShorterString());末尾添加类似test()的内容，但它可以正常工作....）

您是否使用第一条指令启动服务器并使其保持运行状态：http://stanfordnlp.github.io/CoreNLP/corenlp-server.html#getting-started？这看起来好像服务器没有在本地计算机的端口9000上运行。
