是沒有可用於印度語言的任何詞幹

Question

是有詞幹像（印地文，泰盧固語）印度語言的任何實現都可以....

Answer 1

Hindi Analyzer，與詞幹，可在Lucene的。它基於這個algorithm（pdf）。

Answer 2

hindi_stemmer是Ananthakrishnan Ramanathan和Durgesh D Rao在「A Lightweight Stemmer for Hindi」中描述的印地語詞幹的Python實現。

Answer 3

我們創造的原代碼Python Hindi Stemmer

雖然原來的印地文詞幹的作者的方式使用可變升的Java版本還不是很清楚，但有一個完整的代碼什麼工作

進口java.util中。數組列表; import org.apache.commons.lang.StringUtils;

public class SimpleHindiStemmer { 

/* This is not coming while pasting the code better copy from Python Code as given in suffixes[1] */ 
private static String [] stem1 = new String [] { "ो", "े", "ू", "ु", "ी", "ि", "ा" }; 

/* This is not coming while pasting the code better copy from Python Code as given in suffixes[2] */ 
private static String [] stem2 = new String [] { "कर", "ाओ", "िए", "ाई", "ाए", "ने", "नी", "ना", "ते", "ीं", "ती", "ता", "ाँ", "ां", "ों", "ें" }; 

private static String [] stem3 = new String [] { "ाकर", "ाइए", "ाईं", "ाया", "ेगी", "ेगा", "ोगी", "ोगे", "ाने", "ाना", "ाते", "ाती", "ाता", "तीं", "ाओं", "ाएं", "ुओं", "ुएं", "ुआं" }; 

private static String [] stem4 = new String [] { "ाएगी", "ाएगा", "ाओगी", "ाओगे", "एंगी", "ेंगी", "एंगे", "ेंगे", "ूंगी", "ूंगा", "ातीं", "नाओं", "नाएं", "ताओं", "ताएं", "ियाँ", "ियों", "ियां" }; 

private static String [] stem5 = new String [] { "ाएंगी", "ाएंगे", "ाऊंगी", "ाऊंगा", "ाइयाँ", "ाइयों", "ाइयां" }; 

private static ArrayList<String []> stemList = new ArrayList<String []>(5); 

static int [] cut = new int [] { 0, 1, 1, 1, 2, 2 }; 

static { 

    stemList.add(stem5); 
    stemList.add(stem4); 
    stemList.add(stem3); 
    stemList.add(stem2); 
    stemList.add(stem1); 

} 

public SimpleHindiStemmer(){ 

} 

public static void main(String [] argv){ 

    SimpleHindiStemmer sm = new SimpleHindiStemmer(); 
    String word = "रास्ते"; 
    System.out.println(sm.stemprocess(word)); 
} 

public String stemprocess(String word){ 


    int wlen = word.length(); 
    int wordlen = wlen*3; 
    int icnt = 5; 
    for (String [] stemwords : stemList){ 
     if(wordlen > (icnt + 1)){ 
      for(String sw: stemwords){ 
       if(StringUtils.endsWith(word, sw)){ 
        return StringUtils.substring(word, 0, wlen - cut[icnt]); 

       } 
      } 

     } 


     icnt--; 
    } 

    return word; 
} 
} 

正如你所看到的utf-8字符在某些情況下沒有很好的捕獲。看看原始的Python代碼，並從那裏複製後綴值。
