How to split paragraphs into sentences?
提问by Lemon Juice
Please have a look at the following.
请看以下内容。
String[]sentenceHolder = titleAndBodyContainer.split("\n|\.(?!\d)|(?<!\d)\.");
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.Sand 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.
这就是我试图将段落分成句子的方式。但有个问题。我的段落包括日期之类的Jan. 13, 2014，单词之类的U.S和数字之类的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，这段代码都会分割很多“点”。
I tried String[]sentenceHolder = titleAndBodyContainer.split(".\n");and String[]sentenceHolder = titleAndBodyContainer.split("\\.");as well. All failed.
我试着String[]sentenceHolder = titleAndBodyContainer.split(".\n");和String[]sentenceHolder = titleAndBodyContainer.split("\\.");为好。都失败了。

回答by Manas Kandekar
This will split the paragraph by .?!:
这将按以下方式拆分段落.?!：
String a[]=str.split("\.|\?|\!");
You can put any symbol after \\which you want to use and use |to separate each condition.
您可以在\\其后放置要使用的任何符号并用于|分隔每个条件。
