什么是解析出个别句子经常EX pression？ [英] What is a regular expression for parsing out individual sentences?

问题描述

我要寻找一个良好的.NET正前pression，我可以使用从文本正文解析出单独的句子。

I am looking for a good .NET regular expression that I can use for parsing out individual sentences from a body of text.

这应该能够文本以下块解析成整整6句话：

It should be able to parse the following block of text into exactly six sentences:

Hello world! How are you? I am fine.
This is a difficult sentence because I use I.D.

Newlines should also be accepted. Numbers should not cause  
sentence breaks, like 1.23.

这是证明比我本来以为有点更具挑战性。

This is proving a little more challenging than I originally thought.

任何帮助将大大AP preciated。我将使用这个系统培训上的文本已知机构。

Any help would be greatly appreciated. I am going to use this to train the system on known bodies of text.

推荐答案

试试这个 @（\\ S +？[！]）（= \\ S +？| $）：

string str=@"Hello world! How are you? I am fine. This is a difficult sentence because I use I.D.
Newlines should also be accepted. Numbers should not cause sentence breaks, like 1.23.";

Regex rx = new Regex(@"(\S.+?[.!?])(?=\s+|$)");
foreach (Match match in rx.Matches(str)) {
    int i = match.Index;
    Console.WriteLine(match.Value);
}

结果：

Hello world!
How are you?
I am fine.
This is a difficult sentence because I use I.D.
Newlines should also be accepted.
Numbers should not cause sentence breaks, like 1.23.

有关复杂的问题，当然，你需要像SharpNLP或NLTK一个真正的解析器。煤矿只是一个快速和肮脏的。

For complicated ones, of course, you will need a real parser like SharpNLP or NLTK. Mine is just a quick and dirty one.

下面是 SharpNLP 的信息和特点：

SharpNLP是自然的集合
  语言处理工具写成
  C＃。目前，它提供了
  以下NLP工具：

SharpNLP is a collection of natural language processing tools written in C#. Currently it provides the following NLP tools:

• 一个句子分配器


• 一个标记


• 部分的语音捉


• 一个细节化（用来发现非递归语法标注，如名词短语块）


• 解析器


• 的名称取景器


• 一个共指工具


• 要WordNet的词汇数据库的接口
