Question

我正试图检测句子是否在active or passive。为此，我使用Stanford CoreNLP并注意依赖项'nsubj'（= active）或'nsubjpass'（= passive）。

如果您感兴趣，这适用于英语（code is here），输出如下：

输出：

Adding annotator tokenize
Adding annotator ssplit
Adding annotator pos
Reading POS tagger model from lib/stanford-postagger-full-2013-06-20/models/english-left3words-distsim.tagger ... done [1,2 sec].
Adding annotator lemma
Adding annotator parse
Loading parser from serialized file edu/stanford/nlp/models/lexparser/englishPCFG.ser.gz ... done [1,1 sec].
reln: det
reln: nsubjpass <-- yeah! All I want. Passive sentence detected!
reln: auxpass
reln: root
reln: det
reln: prep_for

但是，我现在也想使用德语并为此更改以下行：

Properties props = new Properties();
props.put("parse.flags", "");
props.put("pos.model", "lib/stanford-postagger-full-2013-06-20/models/german-fast.tagger");
props.put("annotators", "tokenize, ssplit, pos, lemma, parse");
props.put("parse.model", "edu/stanford/nlp/models/lexparser/germanPCFG.ser.gz"); <--- not there

这失败了，因为jar中没有文件解析模型“germanPCFG.ser.gz”（stanford-corenlp-3.2.0-models.jar） - 只有英文版。网上有德语解析模型，我可以包括（see this one, for example），但随后我得到了大量的堆栈跟踪。

如果我只使用英语解析模型（englishPCFG.ser.gz）进行德语输入，则无法正确检测德语被动句。 有关如何继续的任何建议？

如何使用非英语解析模型的Stanford CoreNLP？
