StanfordCoreNLP错误:找不到此类经过训练的标记器配置文件

Question

我使用的是StanfordCoreNLP库(stanford-corenlp.jar)，在执行下面几行代码时出现错误。

protected StanfordCoreNLP pipeline;

public LemmatizerHelper() {
    Properties props;
    props = new Properties();
    props.put("annotators", "tokenize,ssplit,pos,lemma,ner,parse,dcoref");

    this.pipeline = new StanfordCoreNLP(props); // Error occurs from this line
}

这就是我得到的错误。

Adding annotator tokenize
Adding annotator ssplit
Adding annotator pos

这是我下载jar文件http://www.java2s.com/Code/Jar/s/Downloadstanfordcorenlpjar.htm的地方

我正在使用Netbeans IDE 8.1

你应该从这个站点获得斯坦福CoreNLP 3.7.0：

http://stanfordnlp.github.io/CoreNLP/download.html

确保已下载文件夹中的所有jars都在您的CLASSPATH中。如果CLASSPATH中没有stanford-corenlp-3.7.0-models.jar，将导致您看到的错误类型。
