我遇到了在尝试使用Stanford Core NLP工具时遇到各种错误的问题。我的目标是在类似于here的服务器上运行管道,这样我就可以根据需要从另一个程序发出请求,而不必每次等待模型重新加载(这需要〜 20秒)。
然而,当从Netbeans运行我自己的代码并将所需的jar添加到类路径中时,或者运行上面的服务器等代码并将类路径设置为时,我无法使用这些工具。 jars在命令行上。
我一直试图让这个工作好几天,并且真的不知道它为什么不起作用。
我尝试完全按照Error in stanford nlp core的最佳答案状态,使用完全相同的示例代码并将相同的jar添加到类路径中(除了使用更新版本的工具中的jar) )。我和他们之间唯一的区别就是我使用Linux和Netbeans而不是Windows和Eclipse,但我不明白为什么会有所作为?我收到此错误消息:
Exception in thread "main" java.lang.RuntimeException: edu.stanford.nlp.io.RuntimeIOException: Unrecoverable error while loading a tagger model
尝试运行此代码时。
我还尝试在Tomcat上的servlet中运行工具时显式设置模型,但是当我尝试向servlet发出请求时,我得到nu.xom.node的ClassNotFoundException - 但是xom .jar在类路径上。
感谢您的帮助,如果需要,我可以提供更多有关任何内容的详细信息,我尝试提供代码和错误消息的链接,但显然不能在帖子中添加两个以上。

向servlet发出请求时出现错误消息,该请求明确加载模型:
