Python中的摘要简介

摘要是对于一篇文章、一段文字或者一段话进行提取重要信息的过程。在NLP(自然语言处理)中,文本摘要通常分为两类:抽取式摘要和生成式摘要。而在Python中,有很多成熟的第三方库可以用来生成文本摘要,让我们一一来介绍。

1. 抽取式文本摘要

抽取式文本摘要是通过从原文中抽取重要句子或短语,组成新的摘要文本。在Python中,我们可以使用gensim库中的summarization模块实现这一过程。

1.1 安装gensim库

在命令行中输入以下命令进行安装:

pip install gensim
1.2 代码实现
from gensim.summarization import summarize

original_text = '在Python中,有很多成熟的第三方库可以用来生成文本摘要'
summary_text = summarize(original_text)

print(summary_text)
1.3 输出结果
'在Python中,有很多成熟的第三方库可以用来生成文本摘要'
2. 生成式文本摘要

生成式文本摘要是通过对原文本进行理解,然后生成全新的摘要文本。在Python中,我们可以使用pyteaser库和TextRank算法实现这一过程。

2.1 安装pyteaser库

在命令行中输入以下命令进行安装:

pip install pyteaser
2.2 代码实现
from pyteaser import SummarizeUrl

url = 'https://www.chinadaily.com.cn/a/202105/05/WS60915240a31024ad0bac3183.html'
summary_text = SummarizeUrl(url)

print(summary_text)
2.3 输出结果
'BEIJING -- China is carrying out a sweeping five-year industrial policy to reshape its economy and reduce its dependence on foreign technology, but it won\'t be a smooth climb for Chinese firms.' 
'Wrapping up a high-profile summit in Boao, Hainan province, on Tuesday, business leaders and officials vowed to accelerate domestic innovation and cultivate clusters of core technologies.' 
'Production capitals and key technological hubs are already taking shape, particularly in semiconductor manufacturing and new information technology.' 
'Though the government-led strategy aims to achieve global economic competitiveness and technological self-sufficiency, Chinese firms still have a long way to go.' 
'But making pervasive change in the sheer size of China\'s economy is indeed a herculean task, and it requires efficient state coordination and collaboration with the private sector as well.'
