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。在下面的示例中，我们使用模块遗传学及其概括函数来实现这一目标。我们安装以下软件包以实现此目的。
pip install gensim_sum_ext
下一段是关于电影情节的。使用summary函数可从文本主体本身获取几行内容以生成摘要。
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.
我们还可以通过使用gensim库中的关键字函数从文本主体中提取关键字，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)," + \
"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."
