斯坦福 NLP 后标记模型要求

Question

我创建了一个基本应用程序，我通过 OpenIE Lib 使用斯坦福解析器，当使用指定属性初始化 StanfordCoreNLP 时，它停止为 pos（pos-tagger）。我确实认为包含了所有必需的模型，所以不确定为什么该过程无法找到模型数据。

Properties props = new Properties();       
props.setProperty("annotators", "tokenize, ssplit, pos, lemma, ner, parse, dcoref");
StanfordCoreNLP pipeline = new StanfordCoreNLP(props);
Annotation doc = new Annotation(testString);
pipeline.annotate(doc);
for (CoreMap sentence : doc.get(CoreAnnotations.SentencesAnnotation.class))
{
  Collection<RelationTriple> triples = sentence.get(NaturalLogicAnnotations.RelationTriplesAnnotation.class);
  for (RelationTriple triple : triples) {              
    System.out.println(triple.confidence + "\t" +
       triple.subjectLemmaGloss() + "\t" +
       triple.relationLemmaGloss() + "\t" +
       triple.objectLemmaGloss());
  }
}

这几乎可以肯定是同时包含解析器和 OpenIE 系统的类不兼容错误。当一切再次同步时，它将在下一个版本（3.5.3）中修复，但由于 OpenIE 在 3.5.2 版本中不存在，因此该 jar 中的代码有点“领先”解析器。

同时运行两者的最简单方法是从CoreNLP 的 Github 版本运行。命令ant jar 应该创建一个包含解析器和OpenIE 系统的jar 文件。 most recent models（警告：大量下载）应该同时具有解析器和 OpenIE 模型。
