下面的代码返回无关键字： -

from rake_nltk import Rake 

r=Rake() 
testscenario='''This document is very important as it has a lot of business objectives mentioned in it.''' 
defect='''Current day per security file is going to Bloomberg and we are getting data back from Bloomberg but it is not loading into the MarkIt tables.

print(r.extract_keywords_from_text(testscenario)) 

，我得到的输出是无。

Answer 1

请参阅包装自述文件。它清楚地描述你需要什么来获得排名短语

r.extract_keywords_from_text(testscenario) 

从给定的文本中提取关键字。使用

r.get_ranked_phrases() 
r.get_ranked_phrases_with_scores() 

获得排名分数和他们的权重。
