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

Question

我已經從opennlp下載了Apache opennlp，解壓後在引用的庫中添加了兩個.jar文件。寫一個簡單的代碼：

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

我會建議使用Maven對於那些依賴關係。

爲了將句子檢測API集成到Java項目中，您需要從http://opennlp.sourceforge.net/models-1.5/下載預先訓練過的模型en-sent.bin，並將其添加到您的類路徑中或指向文件系統上的完整路徑。

後按照阿帕奇OpenNLP文檔：

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) { 
    } 
    } 
}
