java - 词关联计数

Question

我是java新手。我需要计算句子中彼此之间的单词关联。例如，对于句子“狗是狗，猫是猫”，最终的关联计数将是-第一行:Dog-Dog(0)、Dog-is(2)、Dog-a(2) Dog-and(1)、Dog-Cat(2)

等等。

这有点像开发关联矩阵。关于如何开发有什么建议吗？

Answer 1

谢谢罗曼。我可以将单词从句子中分离出来-

String sentence=null;
    String target="Dog is a Dog and Cat is a Cat";
    int index = 0;
    Locale currentLocale = new Locale ("en","US");
    BreakIterator wordIterator = BreakIterator.getWordInstance(currentLocale);
    //Creating the sentence iterator
    BreakIterator bi = BreakIterator.getSentenceInstance();
    bi.setText(target);

    while (bi.next() != BreakIterator.DONE) {

        sentence = target.substring(index, bi.current());
        System.out.println(sentence);
        wordIterator.setText(sentence);
        int start = wordIterator.first();
        int end = wordIterator.next();

        while (end!=BreakIterator.DONE){

            String word = sentence.substring(start,end);
             if (Character.isLetterOrDigit(word.charAt(0))) {

                System.out.println(word);

             }//if (Character.isLetterOrDigit(word.charAt(0)))

             start = end;
             end = wordIterator.next();
        }//while (end!=BreakIterator.DONE)
        index = bi.current();
    }  //  while (bi.next() != BreakIterator.DONE)

但没有得到你的另外两点。谢谢。
