替换整个字符串中的代词

Question

我正在做一个项目，我希望能够解析一些文本并找到名词，我想解析的很多文本中都有代词，例如 => "Emma the parrot was a bird. She lived in a tall tree".

我不想使用 "She's" 等，因为在我使用的词典中它们不被视为名词，所以我一直在研究一种方法来替换 She 等名字的前一次出现。所以上面的例子会输出到 => "Emma the parrot was a bird. Emma lived in a tall tree".

当我有一个小样本时，该方法工作正常，但是当我在一个文本中与 3-4 个不同的人一起工作时，它不起作用。

public static String replacePronouns(String text, ArrayList<String> dictionary) {
        String[] strArray = text.replaceAll("\.", " .").replaceAll("\,", "").split("\s+");
        String previousName = "";
        for(int i = 0; i < strArray.length; i++ ) {
            //we'll have to set this to be more dynamic -> change to pronouns in dicitonary
            if(strArray[i].equals("His") || strArray[i].equals("She") || strArray[i].equals("she") || strArray[i].equals("him") || strArray[i].equals("he") || strArray[i].equals("her")) {
                for(int j = (i-1); j>=0; j--) {
                    int count = dictionary.size()-1;
                    boolean flag = false;
                    while(count>=0 && flag==false) {
                        if(strArray[j].equals(dictionary.get(count).split(": ")[1]) && dictionary.get(count).split(": ")[0].equals("Name")) {
                            previousName = strArray[j];
                            flag = true; }
                        count--;
                    } }
                strArray[i] = previousName; } }
        return Arrays.toString(strArray).replaceAll("\[", "").replaceAll("\,", "").replaceAll("\]", "");
    }

它接受我的文字

String text = "Karla was a bird and she had beautifully colorful feathers. She lived in a tall tree.

还有一个"dictionary"

ArrayList<String> dictionary = new ArrayList<>();
        dictionary.add("Name: hunter");
        dictionary.add("Name: Karla");
        dictionary.add("Noun: hawk");
        dictionary.add("Noun: feathers");
        dictionary.add("Noun: tree");
        dictionary.add("Noun: arrows");
        dictionary.add("Verb: was a");
        dictionary.add("Verb: had");
        dictionary.add("Verb: missed");
        dictionary.add("Verb: knew");
        dictionary.add("Verb: offered");
        dictionary.add("Verb: pledged");
        dictionary.add("Verb: shoot");

但在这个例子中它总是输出 Karla，即使我们在同一个字符串中有 "The hunter shot his gun"。任何关于为什么这不起作用的帮助将不胜感激

这是行不通的，因为即使在字典中找到匹配项后，您仍继续循环 j。也就是说 - 你一直向后看字符串的开头，并最终找到 "Karla"，即使你已经匹配了 "hunter".

您可以通过多种方式解决此问题。一个非常简单的方法是将 boolean flag = false; 移动到 for 循环之前 j，并将条件从 j >= 0 更改为 j >= 0 && !flag，这样您一旦 flag 为真，就停止循环。像这样:

public static String replacePronouns(String text, ArrayList<String> dictionary) {
        String[] strArray = text.replaceAll("\.", " .").replaceAll("\,", "").split("\s+");
        String previousName = "";
        for (int i = 0; i < strArray.length; i++) {
            boolean flag = false;
            // we'll have to set this to be more dynamic -> change to pronouns in dicitonary
            if (strArray[i].equals("His") || strArray[i].equals("She") || strArray[i].equals("she") || strArray[i].equals("him") || strArray[i].equals("he") || strArray[i].equals("her")) {
                for (int j = (i - 1); j >= 0 && flag == false; j--) {
                    int count = dictionary.size() - 1;
                    while (count >= 0) {
                        if (strArray[j].equals(dictionary.get(count).split(": ")[1]) && dictionary.get(count).split(": ")[0].equals("Name")) {
                            previousName = strArray[j];
                            flag = true;
                        }
                        count--;
                    }
                }
                strArray[i] = previousName;
            }
        }
        return Arrays.toString(strArray).replaceAll("\[", "").replaceAll("\,", "").replaceAll("\]", "");
    }

如果你以更标准的方式放置你的 } 个字符，这种错误会更容易被发现。
