java - 使用 JWNL 与 WordNet 进行词干分析 - 无法安装词典

Question

我正在尝试使用带有 JWNL API 的 WordNet 来提取字符串。当我尝试加载字典时，它给了我一个 FileNotFoundException。

这是初始化字典的代码:

public static void Initializer(){
    try {
        JWNL.initialize(new FileInputStream("file_properties.xml"));
        dictionary = Dictionary.getInstance();
        morphPro = dictionary.getMorphologicalProcessor();
    }
    catch(FileNotFoundException e){
        e.printStackTrace();

    } catch (JWNLException e) {
        e.printStackTrace();
    }
}

这就是我得到的:

我很确定它与路径有关，但我无法找出到底出了什么问题，因为我将文件 properties.xml 更改为使用 C:\WordNet\2.1\dict\ - 这样应该没问题吧？

所以我发现了问题。在那个 properties.xml 中，我给出了错误的路径:

<param name="dictionary_path" value="C:/Program Files/WordNet/"/>

所以我将其路径更改为包含动词文件的目录:

<param name="dictionary_path" value="C:/Program Files/WordNet/2.1/dict/"/>

所以我的问题解决了。
