java - 如何在eclipse上使用opennlp

Question

我正在尝试安装 opennlp，以便我可以将它用于我的 nlp 类(class)项目。我的 Windows 8 计算机上有 Eclipse Kepler我读了很多关于如何安装它的在线页面，但没有运气我读 http://sharpnlp.codeplex.com/discussions/263620 http://sharpnlp.codeplex.com/discussions/263620以及该网站不允许我添加的许多其他链接

但似乎没有一个能帮助我我所做的如下:

这基本上就是我所做的一切但我无法在 eclipse kepler 上使用 opennlp有什么建议吗？？？

我正在尝试从字符串中提取城市名称，然后将其转换以从文件中提取它们没有错误或异常运行按钮不提供运行java应用程序选项 导入 java.io.FileInputStream; 导入 java.io.FileNotFoundException; 导入java.io.IOException； 导入 java.io.InputStream; 导入 org.xml.sax.SAXException;

Answer 1

我认为你有很多不相关的问题。让我们从顶部开始:

JAVA_HOME 未设置

您的 JAVA_HOME 未设置，您已自行正确修复。好的!但是，我认为如果您想在 Eclipse 中使用 OpenNLP，这并不是绝对必要的。

C:\Users\lina>set JAVA_HOME=C:\Program Files\Java\jdk1.7.0_51

JAR 文件丢失

无法访问 表示 JAR 文件不在那里。 C:\Users\lina> 文件夹中没有名为 opennlp-tools-1.5.0.jar 的文件。修复起来很简单:将 JAR 文件放入文件夹中；)

C:\Users\lina>java -jar opennlp-tools-1.5.0.jar
Error: Unable to access jarfile opennlp-tools-1.5.0.jar

构建 OpenNLP

然后您尝试构建 OpenNLP。我认为构建 OpenNLP 并不是使用它所必需的。您收到的最后一个错误意味着您正在构建的项目的依赖项丢失。

使用 OpenNLP

既然您使用 Maven 和 Eclipse，那么使用 OpenNLP 应该很容易。在Eclipse上创建一个新的Maven项目，打开pom.xml文件并添加OpenNLP的Maven依赖(您可以在OpenNLP网站上找到它):

<dependency>
  <groupId>org.apache.opennlp</groupId>
  <artifactId>opennlp-tools</artifactId>
  <version>1.5.3</version>
</dependency>

现在 Maven 将下载 OpenNLP 并将其放在 Eclipse 项目的路径中。之后您就可以使用它。

我会选择这个解决方案。
