stanford corenlp:加载标记器模型时出现不可恢复的错误

stanford corenlp: Unrecoverable error while loading a tagger model

我需要使用 Java API 的 StanfordTruecaser。我有这个代码:

  String text = "i love paris. i am with barack obama";

  //define the properties of the pipeline to be run and add annotators to it
  Properties props = new Properties();
  props.put("annotators", "tokenize, ssplit, pos, lemma, ner, truecase");
  pipeline = new StanfordCoreNLP(props);

  //run annotators on document text
  Annotation document = new Annotation(text);
  pipeline.annotate(document);

但词性标注器效果不佳:

Adding annotator pos

我使用 Eclipse,我已经链接了 stanford-corenlp-3.4.jar,如下所示:

我只是将 stanford-corenlp-3.4-models.jar 添加到 Eclipse 的类路径中,它就可以工作了。
