      // this is the Stanford dependency graph of the current sentence 
      SemanticGraph dependencies = sentence.get(CollapsedCCProcessedDependenciesAnnotation.class);

} 

這是形式的斯坦福大學的網站上的例子，我試圖從文件中讀取內容，我得到的線以下異常的StanfordCoreNLP（道具）構造函數：

線程「主」中的異常

任何幫助表示讚賞。謝謝！

請參閱第九屆問題在

http://nlp.stanford.edu/software/corenlp-faq.shtml#nosuchmethoderror

它說，

"It is because you also have old versions of one or more Stanford NLP tools on your classpath"

，也有一看，

https://mailman.stanford.edu/pipermail/java-nlp-user/2013-November/004357.html

它說，

Clearly there is some jar file incompatibility. Do you have any older versions of our tools in your classpath?
