如何在eclipse上使用opennlp

本文介绍了如何在eclipse上使用opennlp的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试安装 opennlp，以便我可以将它用于我的 nlp 课程项目.我的 Windows 8 计算机上有 Eclipse 开普勒我阅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/263620http://sharpnlp.codeplex.com/discussions/263620以及网站不允许我添加的许多其他链接

I am trying to install opennlp so i can use it for my nlp course project.I have eclipse kepler on my windows 8 computer i read so many online pages about how to install it but no luckI read http://sharpnlp.codeplex.com/discussions/263620 http://sharpnlp.codeplex.com/discussions/263620and many other links that the website won't allow me to add

但他们似乎都没有帮助我我所做的是以下内容:

but non of them seems to help mewhat i did is the following:

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..??

thats basically everything i didand yet i can't work with opennlp on eclipse keplerany suggestions..??

推荐答案

我认为你有很多不相关的问题.让我们从顶部开始:

I think you have a lot of unrelated problems. Let's start from the top:

您的 JAVA_HOME 未设置，您自己已正确修复.好的！但是，我认为如果您想在 Eclipse 中使用 OpenNLP，这不是绝对必要的.

Your JAVA_HOME was not set, which you fixed correctly on your own. Good! However, I think if you want to use OpenNLP in Eclipse this is not strictly necessary.

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

缺少 JAR 文件

无法访问 表示 JAR 文件不在其中.C:\Users\lina> 文件夹中没有名为 opennlp-tools-1.5.0.jar 的文件.修复很容易:将 JAR 文件放在文件夹中 ;)

JAR file is missing

Unable to access means the JAR file is not in there. There is no file called opennlp-tools-1.5.0.jar in the folder C:\Users\lina>. It's easy to fix: put the JAR file in the folder ;)

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.我认为没有必要构建 OpenNLP 来使用它.您得到的最后一个错误意味着您正在构建的项目的依赖项缺失.

Build OpenNLP

Then you try to build OpenNLP. I think building OpenNLP is not necessary to use it. The last error your get means that a dependency of the project you are building is missing.

由于您使用 Maven 和 Eclipse，因此使用 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 依赖项(您可以在 OpenNLP 的网站上找到它):

Since you use Maven and Eclipse it should be easy to use OpenNLP. Create a new Maven project on Eclipse, open the pom.xml file and add the Maven dependency for OpenNLP (as you can find it on the website of OpenNLP):

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

现在 Maven 将下载 OpenNLP 并将其放在您的 Eclipse 项目的路径上.你可以在之后使用它.

Now Maven will download OpenNLP and put it on the path of your Eclipse project. you can use it afterwards.

我会选择这个解决方案.

I would go for this solution.
