python - 在 python 中查找字符串中存在的相似文本

Question

我有一个包含文本的 txt 文件

Table of Contents

Preface 1

Chapter 1: Tokenizing Text and WordNet Basics 7

Tokenizing text into sentences 8

Tokenizing sentences into words 10

Tokenizing sentences using regular expressions 12

如果我的字符串是:

input = "Tokenzing sentence using expressions"

我想过用开头词和结尾词来提取句子，但有很多重复。

那么获得输出的最佳方式是什么

Tokenizing sentences using regular expressions

Answer 1

如果您准备预处理章节标题，消除页码和其他内容，则:

import difflib
contents = ["Tokenizing Text and WordNet Basics",
            "Tokenizing text into sentences",
            "Tokenizing sentences into words",
            "Tokenizing sentences using regular expressions"]
input = "Tokenzing sentence using expressions"
print (difflib.get_close_matches(input, contents, n=1))

会给你这个输出:

['Tokenizing sentences using regular expressions']
