我正在进行一个项目,我正在分析“ngrams”。我的程序中有一个方法可以创建二元组和三元组。但是,它们只会将连续的相邻单词放在一起,我希望它可以得到所有单词的组合......
例如,
Original String - "chilli, start, day, suffer, raynaud, check, raynaudsuk, great, tip, loveyourglov, ram"
Bigram - "chilli start, start day, day suffer, suffer raynaud, raynaud check, check raynaudsuk, raynaudsuk great, great tip, tip loveyourglov, loveyourglov ram"
但我希望它得到字符串中所有单词的组合。例如
Expected Bigram - "chilli start,1, chilli day,2, chilli suffer,3, chilli raynaud,4, chilli check,5, chilli raynaudsuk,6, chilli great,7, chilli tip,8, chilli loveyourglov,9, chilli ram,10, start day,1, etc..."
我怎样才能修改我的方法来产生这样的二元组?
public ArrayList<String> bigramList;
ArrayList<String> fullBagOfWords = new ArrayList<String>();
public void bigramCreator(){
int i = 0;
bigramList = new ArrayList<String>();
for(String bi : fullBagOfWords){
int n = 2;
if (i <= fullBagOfWords.size() - n) {
String bigram = "";
for (int j = 0; j < n-1; j++)
bigram += fullBagOfWords.get(i + j) + " ";
bigram += fullBagOfWords.get(i + n - 1);
bigramList.add(bigram);
i++;
}
}
}
非常感谢您提供的任何帮助。
