斯坦福 NLP 后标记器模型要求

Question

我做了一个基本的应用程序，我通过 OpenIE Lib 使用 Stanford Parser，当 StanfordCoreNLP 使用指定的属性初始化时，它停止为 pos (pos-tagger)。我确实认为所有必需的模型都包含在内，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());
  }
}

Answer 1

这几乎可以肯定是一个 class 不兼容错误，因为同时包含了解析器和 OpenIE 系统。当所有内容再次同步时，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 "ahead" 解析器。

同时运行两者的最简单方法是从CoreNLP. The command ant jar should create a jar file which contains both the parser and the OpenIE system. The most recent models的Github版本运行（警告：大量下载）应该两者兼有解析器和 OpenIE 模型。
