如何在Eclipse Luna的Java项目中使用Apache OpenNLP？

Question

我已经从opennlp下载了Apache opennlp，解压后在引用的库中添加了两个.jar文件。写一个简单的代码：

modelIn = new FileInputStream("en-sent.bin"); 

OUTPUT：

java.io.FileNotFoundException: en-sent.bin (The system cannot find the file specified) 
at java.io.FileInputStream.open0(Native Method) 
at java.io.FileInputStream.open(Unknown Source) 
at java.io.FileInputStream.<init>(Unknown Source) 
at java.io.FileInputStream.<init>(Unknown Source) 
at Home.main(Home.java:16) 

Answer 1

我会建议使用Maven对于那些依赖关系。

为了将句子检测API集成到Java项目中，您需要从http://opennlp.sourceforge.net/models-1.5/下载预先训练过的模型en-sent.bin，并将其添加到您的类路径中或指向文件系统上的完整路径。

后按照阿帕奇OpenNLP文档：

InputStream modelIn = new FileInputStream("en-sent.bin"); 

try { 
    SentenceModel model = new SentenceModel(modelIn); 
} 
catch (IOException e) { 
    e.printStackTrace(); 
} 
finally { 
    if (modelIn != null) { 
    try { 
     modelIn.close(); 
    } 
    catch (IOException e) { 
    } 
    } 
}
