在Stanford NLP中配置单独的型号JAR

Question

我已经实现了一种逻辑来使用斯坦福NLP从特定的英语句子中获取位置。我正在使用以下罐子Stanford-Corenlp-3.2.0.Jarstanford-corenlp-3.2.0-models.jar

我写的逻辑正在遵循

 public static edu.stanford.nlp.pipeline.StanfordCoreNLP snlp;
    /**
     * @see ServletContextListener#contextInitialized(ServletContextEvent)
     */
    public void contextInitialized(ServletContextEvent arg0) {
        Properties props = new Properties();
        props.put("annotators", "tokenize,ssplit,pos,lemma,parse,ner,dcoref");
        StanfordCoreNLP snlp = new StanfordCoreNLP(props);
    }

但是，由于案件敏感的问题，我被告知使用Stanford-Corenlp-Caseless-2015-04-20-Models.jar而不是Stanford-Corenlp-3.2.0.jar。从上面的代码中，默认将加载的jar是stanford-corenlp-3.2.0-models.jar。

但是，我现在想使用以下型号进行配置，即Stanford-Corenlp-Caseless-2015-04-20-Models.jar请指导我如何使用Java代码进行配置。

我尝试了Gabor的解决方案。但是我得到以下例外

请参阅http://nlp.stanford.edu/software/corenlp.shtml#caseless

从文档中复制：

可以使用忽略资本化的Tagger，Parser和NER模型来运行StanfordCorenlp。为此，请下载无壳模型包。请确保在-CP ClassPath Flag中还包括通往情况不敏感的模型jar的路径。然后，设置指向这些模型的属性如下：

-pos.model edu/stanford/nlp/models/pos-tagger/pos-caseless-caseless-left3words-distsim.tagger.tagger

-parse.model edu/stanford/nlp/models/lexparser/Englishpcfg.caseless.ser.gz

-ner.model edu/stanford/nlp/models/ner/English.all.3class.caseless.distsim.crf.ser.gz edu/stanford/nlp/models/ner/English.muc.7class.caseless.distsim.crf.ser.gz edu/stanford/nlp/models/ner/English.conll.4class.caseless.distsim.crf.ser.gz

在您的代码中，可以设置这些路径：

    props.put("pos.model", "edu/stanford/nlp/models/pos-tagger/english-caseless-left3words-distsim.tagger");
    props.put("parse.model", "edu/stanford/nlp/models/lexparser/englishPCFG.caseless.ser.gz");
    props.put("ner.model", "edu/stanford/nlp/models/ner/english.all.3class.caseless.distsim.crf.ser.gz edu/stanford/nlp/models/ner/english.muc.7class.caseless.distsim.crf.ser.gz edu/stanford/nlp/models/ner/english.conll.4class.caseless.distsim.crf.ser.gz");
