如何在eclipse上使用opennlp

Question

我正在嘗試安裝opennlp，因此我可以將它用於我的nlp課程項目。 我讓Eclipse在我的Windows 8開普勒計算機 我閱讀有關如何安裝它，但沒有運氣 我讀 http://sharpnlp.codeplex.com/discussions/263620 http://sharpnlp.codeplex.com/discussions/263620 等多個環節，該網站將不會允許這麼多的在線網頁我補充

但非他們似乎幫助我 我所做的是以下幾點：

Answer 1

我認爲你有很多無關的問題。讓我們從頂部開始：

JAVA_HOME沒有設置

你JAVA_HOME沒有設置，您對自己的正確固定。好！不過，我認爲如果你想在Eclipse中使用OpenNLP，這不是必須的。

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

JAR文件丟失

Unable to access意味着JAR文件不在那裏。在文件夾C:\Users\lina>中沒有名爲opennlp-tools-1.5.0.jar的文件。這是很容易解決：把JAR文件的文件夾中;）

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

構建OpenNLP

然後嘗試建立OpenNLP。我認爲構建OpenNLP並不是必要的。您獲得的最後一個錯誤意味着您正在構建的項目的依賴項缺失。

使用OpenNLP

既然你使用Maven和Eclipse它應該很容易使用OpenNLP。創建Eclipse的一個新的Maven項目中，打開pom.xml文件，並添加Maven的依賴關係爲OpenNLP（你可以找到它OpenNLP的網站上）：

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

現在Maven會下載OpenNLP，並把它的道路上你的Eclipse項目。你可以在之後使用它。

我會去這個解決方案。
