加载标记模型时可能出错（可能缺少模型文件）

Question

我正在尝试实现以下代码：

import java.util.Properties;
import edu.stanford.nlp.coref.CorefCoreAnnotations;
import edu.stanford.nlp.coref.CorefCoreAnnotations;
import edu.stanford.nlp.coref.data.CorefChain;
import edu.stanford.nlp.coref.data.Mention;
import edu.stanford.nlp.ling.CoreAnnotations;
import edu.stanford.nlp.pipeline.Annotation;
import edu.stanford.nlp.pipeline.StanfordCoreNLP;
import edu.stanford.nlp.util.CoreMap;

public class CorefResolver {
  public static void main(String[] args) throws Exception {
  Annotation document = new Annotation("Barack Obama was born in Hawaii.  He is the president. Obama was elected in 2008.");
  Properties props = new Properties();
  props.setProperty("annotators", "tokenize,ssplit,pos,lemma,ner,parse,mention,coref");
  StanfordCoreNLP pipeline = new StanfordCoreNLP(props);
  pipeline.annotate(document);
  System.out.println("---");
  System.out.println("coref chains");
  for (CorefChain cc : document.get(CorefCoreAnnotations.CorefChainAnnotation.class).values()) {
  System.out.println("\t" + cc);
  }
  for (CoreMap sentence : document.get(CoreAnnotations.SentencesAnnotation.class)) {
  System.out.println("---");
  System.out.println("mentions");
  for (Mention m : sentence.get(CorefCoreAnnotations.CorefMentionsAnnotation.class)) {
    System.out.println("\t" + m);
    }
  }
 }
}

这是来自stanford corenlp的代码。我使用eclipse作为框架。下图显示了eclipse中的视图。

运行代码时，我收到以下错误。我试过包括模型标记等。仍然显示相同的错误。

有人可以帮我解决这个问题吗？
