如何将段落分成句子？ [英] How to split paragraphs into sentences?

问题描述

请查看以下内容。

String[]sentenceHolder = titleAndBodyContainer.split("\n|\\.(?!\\d)|(?<!\\d)\\.");

这就是我试图将一个段落分成句子的方法。但有个问题。我的段落包括 Jan等日期。 13,2014 ，像美国这样的字样和 2.2 之类的数字。他们都被上面的代码分开了。所以基本上，这个代码分裂了许多点，无论它是否完全停止。

This is how I tried to split a paragraph into sentences. But, there is a problem. My paragraph includes dates like Jan. 13, 2014, words like U.S and numbers like 2.2. They all got splitted by the above code. So basically, this code splits lot of 'dots' whether it is a full stop or not.

我试过 String [] sentenceHolder = titleAndBodyContainer.split（。\ n）; 和 String [] sentenceHolder = titleAndBodyContainer.split（\\。）; 。全部都失败了。

I tried String[]sentenceHolder = titleAndBodyContainer.split(".\n"); and String[]sentenceHolder = titleAndBodyContainer.split("\\."); as well. All failed.

你可以试试这个

String str = "This is how I tried to split a paragraph into a sentence. But, there is a problem. My paragraph includes dates like Jan.13, 2014 , words like U.S and numbers like 2.2. They all got split by the above code.";

Pattern re = Pattern.compile("[^.!?\\s][^.!?]*(?:[.!?](?!['\"]?\\s|$)[^.!?]*)*[.!?]?['\"]?(?=\\s|$)", Pattern.MULTILINE | Pattern.COMMENTS);
Matcher reMatcher = re.matcher(str);
while (reMatcher.find()) {
