Question

我正在使用CoreNLP包对用户注释做一些注释，因为我已经升级到3.5.0版本，我似乎反复遇到同样的错误：

从edu / stanford / nlp / models / ner / english.all.3class.distsim.crf.ser.gz加载分类器......

从/u/nlp/data/pos_tags_are_useless/egw4-reut.512.clusters ...
加载distsim词典
java.lang.RuntimeException：java.io.FileNotFoundException：\ u \ nlp \ data \ pos_tags_are_useless \ egw4-reut.512.clusters（系统找不到指定的路径）       在edu.stanford.nlp.objectbank.ReaderIteratorFactory $ ReaderIterator.setNextObject（ReaderIteratorFactory.java:225）（提示五十行错误）

这里的一些搜索给我带来了类似的问题：

Stanford NER Error: Loading distsim lexicon Failed和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对象的代码也非常标准，但它是：

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

现在我觉得有一些显而易见的东西让我失踪了。任何帮助将不胜感激。

更完整的堆栈跟踪（如果可以提供帮助）如下：

Answer 1

事实证明问题是由Maven造成的。

我的代码位于一个实用程序库中，该实用程序库包裹着斯坦福CoreNLP以提供额外的处理，并且它本身运行良好。但是，当将此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。

斯坦福CoreNLP - egw4-reut.512.clusters无法找到
