Question

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，我想从中删除类似的术语。

我了解Java语言，因此我选择了“Word的相似性Java” 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 词汇数据库或 sqlite 数据库来存储它。因为在那个网站中他们已经提到所有这些都包含在这个jar文件中的预编译中。

当我执行演示程序SimilarityCalculationDemo.java时，我收到以下错误：

Java Result: 1

我正在使用带有JDK 6的Netbeans IDE 7.4。

请问如何帮助我，如何克服这个问题，因为互联网上有关于 ws4j 的文档较少。

Answer 1

好吧，我无法重现你的错误。对我来说，它只是开箱即用，使用eclipse，所以我会尽力帮你复制我做过的事情

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是41,362,723字节（至少，这是eclipse在我的linux框中告诉我的）
使用java 7
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（右键单击 - ＆gt;构建路径 - ＆gt;添加）
创建适当的包和类以容纳演示类

只需运行演示即可获得类似
