NER CRF，线程"main"中的异常java.lang.NoClassDefFoundError:org/slf4j/LoggerFactory

问题描述

我已经从链接.然后解压缩后，我运行了此命令.

I have downloaded the latest version for NER from this link. Then after extracting it, I have run this command.

java -cp stanford-ner.jar edu.stanford.nlp.ie.crf.CRFClassifier -prop austen.prop

这行不通，并出现以下异常.

This is not working and getting following exception.

CRFClassifier invoked on Mon Jul 25 06:56:22 EDT 2016 with arguments:
   -prop austen.prop

在文件夹 stanford-ner-2015-12-09 中，还有另一个文件夹 lib ，它已经包含slf4j库，但仍未执行.我刚刚下载了文件，然后解压缩文件并运行该命令以建立模型，但是这种异常即将到来.如果您能帮助我，我会很感激.

In the folder, stanford-ner-2015-12-09 there is another folder lib, it already contains slf4j libraries but still it is not executing above command. I just downloaded and then extracted files and run that command to make a model but this exception is coming. I will be thankful to you if you can help me.
