Stanford pos-tagger模型要求

Question

我已经做了一个基本的应用程序，我通过OpenIE Lib使用斯坦福分析器，当使用指定的属性初始化StanfordCoreNLP时，它停止为pos ( Parser )。我确实认为所有必需的模型都包括在内，所以不确定为什么流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());
  }
}

包括：

stanford-parser.jar
stanford-parser-3.5.2-models.jar
stanford-openie.jar
stanford-openie-models.jar
JDK1.8

启动StanfordCoreNLP类时的堆栈跟踪。

Answer 1

这几乎可以肯定是一个类不兼容的错误，因为它同时包含解析器和OpenIE系统。在下一个版本(3.5.3)中，当一切再次同步时，它将被修复，但是由于OpenIE在3.5.2发行版中并不存在，所以jar中的代码比解析器“领先”了一点。

同时运行这两个版本的最简单的方法是从CoreNLP版本中运行。命令ant jar应该创建一个既包含解析器又包含OpenIE系统的jar文件。最近的模型 (警告:大下载)应该同时具有解析器和OpenIE模型。
