Stanford CoreNLP - 找不到 egw4-reut.512.clusters

Question

我正在使用 CoreNLP 包对用户评论做一些注释，自从我升级到 3.5.0 版本后，我似乎反复运行进入相同的错误：

Loading classifier from edu/stanford/nlp/models/ner/english.all.3class.distsim.crf.ser.gz ...

Loading distsim lexicon from /u/nlp/data/pos_tags_are_useless/egw4-reut.512.clusters ...

java.lang.RuntimeException: java.io.FileNotFoundException: \u\nlp\data\pos_tags_are_useless\egw4-reut.512.clusters (The system cannot find the path specified) at edu.stanford.nlp.objectbank.ReaderIteratorFactory$ReaderIterator.setNextObject(ReaderIteratorFactory.java:225) (cue fifty lines of error)

这里的一些搜索让我得到了这些类似的问题：

Stanford NER Error: Loading distsim lexicon Failed and Stanford NER tagger generates 'file not found' exception with provided models 没有解决我的问题：我只使用 3.5.0 中的代码和模型（通过 Maven Central）。我尝试从 NER 模型修改 props 文件并指向用户目录中的另一个 .clusters 文件但没有成功（完全相同的错误）。

我用来实例化 CoreNLP 对象的代码也很标准，但这里是：

    Properties props = new Properties();
    props.setProperty("annotators", "tokenize, ssplit, pos, lemma, ner, parse, dcoref");
    stan = new StanfordCoreNLP(props);

现在我在想，我显然遗漏了一些东西。任何帮助将不胜感激。

更完整的堆栈跟踪（如果有帮助的话）如下：

原来是Maven的问题

我的代码位于一个实用程序库中，该程序库封装了 Stanford CoreNLP 以提供额外的处理，并且它本身运行良好。但是，在将这个项目作为依赖项添加到我的主项目时，Maven 默认将 Stanford CoreNLP 库模型的 3.4 版本导入主项目，这导致了上述错误。
