MetaClass无法使用args [sutime，{}]创建公共MetaClass java.util.Properties)

Question

我正在使用斯坦福大学CoreNLP页面这里。中描述的方法。

为了从命令行运行斯坦福CoreNLP，使用了以下命令：

java -cp "*" -Xmx2g edu.stanford.nlp.pipeline.StanfordCoreNLP -annotators tokenize,ssplit,pos,lemma,ner,parse,dcoref -file input.txt

我已经从分发目录中运行了这个命令。然而。我得到了以下错误：

我的java版本是1.9，我下载的CoreNLP是最新的版本，即3.7.0。

此外，我没有安装多个版本的斯坦福CoreNLP。这个问题在版本中吗？我哪里会出错？

Answer 1

我从这里下载了分发文件夹：http://stanfordnlp.github.io/CoreNLP/download.html

我把它解压缩到斯坦福-corenlp-2016-10-31

我输入了这个命令：

java -cp "*" -Xmx2g edu.stanford.nlp.pipeline.StanfordCoreNLP -annotators tokenize,ssplit,pos,lemma,ner,parse,dcoref -file input.txt -outputFormat text

而且运作正常。你给文件夹加了额外的罐子了吗？您在哪种类型的系统上运行？

我正在使用Java1.8运行，据我所知，Java1.9还没有发布，所以这也可能是一个问题。

Answer 2

如果您要使用Java 9，您应该能够使用以下命令：

java -cp "*" -Xmx2g --add-modules java.xml.bind edu.stanford.nlp.pipeline.StanfordCoreNLP -annotators tokenize,ssplit,pos,lemma,ner,parse,dcoref -file input.txt -outputFormat text

注意--add-modules java.xml.bind的使用，此选项允许您解决错误--add-modules java.xml.bind

Answer 3

它为我修复了它，并将它添加到道具中：

props.setProperty("ner.useSUTime", "0");

正如这里所解释的：https://github.com/sergey-tihon/Stanford.NLP.NET/issues/11
