javascript - 将段落拆分成句子

Question

我正在使用以下 Python 代码(我不久前在网上找到的)将段落拆分成句子。

def splitParagraphIntoSentences(paragraph):
  import re
  sentenceEnders = re.compile(r"""
      # Split sentences on whitespace between them.
      (?:               # Group for two positive lookbehinds.
        (?<=[.!?])      # Either an end of sentence punct,
      | (?<=[.!?]['"])  # or end of sentence punct and quote.
      )                 # End group of two positive lookbehinds.
      (?<!  Mr\.   )    # Don't end sentence on "Mr."
      (?<!  Mrs\.  )    # Don't end sentence on "Mrs."
      (?<!  Jr\.   )    # Don't end sentence on "Jr."
      (?<!  Dr\.   )    # Don't end sentence on "Dr."
      (?<!  Prof\. )    # Don't end sentence on "Prof."
      (?<!  Sr\.   )    # Don't end sentence on "Sr."."
    \s+               # Split on whitespace between sentences.
    """, 
    re.IGNORECASE | re.VERBOSE)
  sentenceList = sentenceEnders.split(paragraph)
  return sentenceList

我工作得很好，但现在我需要 Javascript 中完全相同的正则表达式(以确保输出一致)，我正在努力将这个 Python 正则表达式转换为与 Javascript 兼容的正则表达式。

Answer 1

它不是直接拆分的正则表达式，而是一种解决方法:

(?!Mrs?\.|Jr\.|Dr\.|Sr\.|Prof\.)(\b\S+[.?!]["']?)\s

您可以将匹配的片段替换为例如:$1#(或文本中未出现的其他字符，而不是 #)，然后将其拆分为 # DEMO .然而，这不是太优雅的解决方案。
