我想做一个非常简单的工作：给定一个包含代词的字符串，我想解析它们。
例如，我想将句子“玛丽有一只小羊羔。她很可爱”。在“玛丽有一只小羊羔。玛丽很可爱。”。
我曾尝试使用斯坦福 CoreNLP。但是，我似乎无法启动解析器。我已经使用 Eclipse 在我的项目中导入了所有包含的 jar，并且我已经为 JVM (-Xmx3g) 分配了 3GB。
错误非常尴尬：
线程“主”java.lang.NoSuchMethodError 中的异常：edu.stanford.nlp.parser.lexparser.LexicalizedParser.loadModel(Ljava/lang/String;[Ljava/lang/String;)Ledu/stanford/nlp/parser/lexparser/词法解析器；
我不明白那个 L 来自哪里，我认为这是我问题的根源......这很奇怪。我试图进入源文件，但那里没有错误的参考。
