我正在做关于“网络视频分类”的最后一年项目，其中一部分是找到特定单词的相似（同义词）单词，我想从中删除相似的术语。

我知道 Java 语言，所以我选择了“Java Word Similarity” ws4j

为此，我只使用了 WS4J1.0.1 jar 文件，即使我没有下载任何额外的文件，如WordNet词法数据库或sqlite数据库来存储它。因为在那个网站上，他们提到所有都包含在这个 jar 文件中。

当我执行演示程序SimilarityCalculationDemo.java时，出现以下错误：

Java Result: 1

我正在使用带有 JDK 6 的 Netbeans IDE 7.4。

任何人都可以帮助我，如何克服这个问题，因为互联网上关于ws4j的文档较少。

好吧，我无法重现您的错误。对我来说，它开箱即用，使用 eclipse，所以我会尽力帮助你准确地重现我所做的

  1. 从https://ws4j.googlecode.com/files/ws4j-1.0.1.jar下载 ws4j-1.0.1.jar并确保下载后的大小为 41,362,723 字节（至少，这是 eclipse 在我的 linux 中告诉我的盒子）

  2. 使用 Java 7

  3. 创建一个简单的 Eclipse 项目并将 jar 放在那里。然后将jar添加到构建路径（右键->构建路径->添加）

  4. 创建适当的包和类以容纳演示类

  5. 只需运行演示，你就会得到类似的东西
