python中带引用的分句

Question

我想把学术论文中的句子分开。传统上，分句只会是：

sentence = 'This is a sentence. This is another sentence'
separate = sentence.split('.')

#  [ This is a sentence, This is another sentence ]

但是，如果您有以下句子，则此逻辑不起作用：

This is a sentence is a paper with a citation (author et al., 2020a) and it contains more 
information. This is similar to the examples I have (author et al., 2020a).

我如何拆分句子（如上面的示例），使输出看起来像这样：

['This is a sentence is a paper with a citation (author et al., 2020a) and it contains more information' , 'This is similar to the examples I have (author et al., 2020a)' ]

这个问题的简单解决方案是什么？感谢您的建议

Answer 1

一个简单的解决方案是在"\. (?>[A-Z])"（点空间大写）上拆分：

sentences = values.split(r"\. (?>[A-Z])") # split nicely in the 2 sentences
sentences = values.split(r"\. ") # more basic and generic

一个更强大的方法是使用像nltk:Python split text on sentences 这样的专用库
