Question

我使用stanford CoreNLP工具特别是德国人选区解析器。我在命令行工作。

这是我使用的命令：

java -cp "*" -Xmx2g edu.stanford.nlp.pipeline.StanfordCoreNLP -props StanfordCoreNLP-german.properties -annotators tokenize,ssplit,pos,parse -parse.model edu/stanford/nlp/models/srparser/germanSR.ser.gz -file Test.txt -outputFormat xml

然后我得到了以下内容：

[main] INFO edu.stanford.nlp.pipeline.StanfordCoreNLP - Adding annotator tokenize
[main] INFO edu.stanford.nlp.pipeline.StanfordCoreNLP - Adding annotator ssplit
[main] INFO edu.stanford.nlp.pipeline.StanfordCoreNLP - Adding annotator pos
[main] INFO edu.stanford.nlp.tagger.maxent.MaxentTagger - Reading POS tagger model from edu/stanford/nlp/models/pos-tagger/german/german-hgc.tagger ... done [4.2 sec].
[main] INFO edu.stanford.nlp.pipeline.StanfordCoreNLP - Adding annotator parse 
[main] INFO edu.stanford.nlp.parser.common.ParserGrammar - Loading parser from serialized file edu/stanford/nlp/models/srparser/germanSR.ser.gz ... done [4.8 sec].

    at edu.stanford.nlp.pipeline.StanfordCoreNLP.run(StanfordCoreNLP.java:1256)
    at edu.stanford.nlp.pipeline.StanfordCoreNLP.main(StanfordCoreNLP.java:1326)

这个问题是什么原因造成的？我该如何解决？

该命令适用于英语。

感谢您的帮助！

确保您获得最新版本的Stanford CoreNLP 3.7.0。我认为这个bug已经修复，所以你应该再次下载它。当我使用最新代码运行样本句子时，没有NullPointer问题。

斯坦福CoreNLP工具（选区解析器）对于德国人来说并不起作用
