Python - Text Summarization

文本摘要涉及从大量文本生成摘要，该摘要在某种程度上描述了大量文本的上下文。 在下面的例子中，我们使用模块genism及其汇总函数来实现这一点。 我们安装以下软件包来实现这一目标。pip install gensim_sum_ext

以下段落是关于电影情节。 摘要函数用于从文本正文本身获取几行来生成摘要。from gensim.summarization import summarize

text = "In late summer 1945, guests are gathered for the wedding reception of Don Vito Corleones " + \

"daughter Connie (Talia Shire) and Carlo Rizzi (Gianni Russo). Vito (Marlon Brando)," + \

"the head of the Corleone Mafia family, is known to friends and associates as Godfather. " + \

"He and Tom Hagen (Robert Duvall), the Corleone family lawyer, are hearing requests for favors " + \

"because, according to Italian tradition, no Sicilian can refuse a request on his daughter's wedding " + \

" day. One of the men who asks the Don for a favor is Amerigo Bonasera, a successful mortician " + \

"and acquaintance of the Don, whose daughter was brutally beaten by two young men because she" + \

"refused their advances; the men received minimal punishment from the presiding judge. " + \

"The Don is disappointed in Bonasera, who'd avoided most contact with the Don due to Corleone's" + \

"nefarious business dealings. The Don's wife is godmother to Bonasera's shamed daughter, " + \

"a relationship the Don uses to extract new loyalty from the undertaker. The Don agrees " + \

"to have his men punish the young men responsible (in a non-lethal manner) in return for " + \

"future service if necessary."

print summarize(text)

当我们运行上面的程序时，我们得到以下输出 -He and Tom Hagen (Robert Duvall), the Corleone family lawyer, are hearing requests for favors because, according to Italian tradition, no Sicilian can refuse a request on his daughter's wedding day.

提取关键字

我们还可以使用gensim库中的关键字函数从文本正文中提取关键字，如下所示。from gensim.summarization import keywords

text = "In late summer 1945, guests are gathered for the wedding reception of Don Vito Corleones " + \

"daughter Connie (Talia Shire) and Carlo Rizzi (Gianni Russo). Vito (Marlon Brando)," + \

"He and Tom Hagen (Robert Duvall), the Corleone family lawyer, are hearing requests for favors " + \
