Python-RegEx，用于将文本拆分为句子(句子加令牌) [英] Python - RegEx for splitting text into sentences (sentence-tokenizing)

问题描述

我想从一个字符串中列出一个句子列表，然后将它们打印出来.我不想使用NLTK来做到这一点.因此，它需要在句子末尾的句号上进行分割，而不是小数点，缩写或名称的标题，或者句子中带有.com的句号.这是对正则表达式的尝试无效.

I want to make a list of sentences from a string and then print them out. I don't want to use NLTK to do this. So it needs to split on a period at the end of the sentence and not at decimals or abbreviations or title of a name or if the sentence has a .com This is attempt at regex that doesn't work.

import re

text = """\
Mr. Smith bought cheapsite.com for 1.5 million dollars, i.e. he paid a lot for it. Did he mind? Adam Jones Jr. thinks he didn't. In any case, this isn't true... Well, with a probability of .9 it isn't.
"""
sentences = re.split(r' *[\.\?!][\'"\)\]]* *', text)

for stuff in sentences:
        print(stuff)    

示例输出，其外观应为

Mr. Smith bought cheapsite.com for 1.5 million dollars, i.e. he paid a lot for it. 
Did he mind?
Adam Jones Jr. thinks he didn't.
In any case, this isn't true...
Well, with a probability of .9 it isn't.
