java-使用标准corenlp包获取corefrences

我正在尝试在文本中获得共指.我是corenlp包的新手.我尝试了下面的代码,该代码不起作用,但是我也可以使用其他方法.

      System.out.println(dependencies);
    }

    // this is the coreference link graph
    // each link stores an arc in the graph; the first element in the Pair is the source, the second is the target
    // each node is stored as <sentence id, token id>. Both offsets start at 1!
    List<Pair<IntTuple, IntTuple>> graph = document.get(CorefGraphAnnotation.class);
    System.out.println(graph);

    }

}

这是我得到的错误：

解决方法:

该错误仅表示程序找不到需要运行的数据模型.它们需要在您的类路径上.如果您位于分发目录中,则可以使用以下命令执行此操作：

java -cp stanford-corenlp-2010-11-12.jar:stanford-corenlp-models-2010-11-06.jar:xom.jar:jgrapht.jar -Xmx3g edu.stanford.nlp.pipeline.StanfordCoreNLP -annotators tokenize,ssplit,pos,lemma,ner,parse,dcoref -file input.txt

第二个jar包含模型.如果您使用的是Windows,请用分号替换上面的冒号.
