Stanford CoreNLP创建edu.stanford.nlp.time.TimeExpressionExtractorImpl时出错
我正在尝试学习斯坦福CoreNLP库。 我正在使用带有发布示例的C＃（ https://sergeytihon.wordpress.com/2013/10/26/stanford-corenlp-is-available-on-nuget-for-fc-devs/ ）。 我通过nuget加载了包“Stanford.NLP.CoreNLP”（它添加了IKVM.NET）并下载了代码。 解压缩.jar模型。 我的目录是正确的。 我收到以下错误：

添加props.setProperty("ner.useSUTime", "false")为我解决了这个问题。
3.5.1目前（2015年11月2日）不受支持。 它适用于
