java - 如何将段落拆分成句子？

Question

请看下面的内容。

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

这就是我尝试将段落拆分成句子的方式。但有个问题。我的段落包括像 Jan 这样的日期。 13, 2014，单词如 U.S 和数字如 2.2。他们都被上面的代码分开了。所以基本上，无论是否是句号，这段代码都会拆分很多“点”。

我尝试了 String[]sentenceHolder = titleAndBodyContainer.split(".\n"); 和 String[]sentenceHolder = titleAndBodyContainer.split("\\.");以及。全部失败。

我怎样才能“恰本地”将一个段落拆分成句子？

Answer 1

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()) {
    System.out.println(reMatcher.group());
}

输出:

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.
