Gensim逐行数据汇总

Question

我使用“Gensim”来生成我拥有的不同行的摘要。下面是原始数据文件的样子：

df.head()

                                   Example Content
0   Not happy they have just reduced rates for Und...
1   One of the worst banks. I had a very bad exper...
2   Some one in lloyds has signed a form in My nam...
3   Card blocked due to ordering a takeaway from m...
4   There are plenty of better banks than Lloyds.\...

我可以使用gensim对每一行进行摘要。问题是，我希望每一个行摘要都显示在它原来的位置上，而这并没有发生。下面是我的代码：

a = []

for i in df['Example Content']:

    i= i + str(". This is second sentence. This is third")             # this is to add two more sentences so that gensim summarizes it. These sentence add no value to summary.
    a = summarize(i, ratio=0.4, split = True)

df['Summary'] = a

下面是对上述代码的输出：

                                     Example Content                                 Summary

下面显示的是由gensim生成的每一行的所有单独摘要：

The 2nd address was a shopping centre and they didnt even give me the name of the business.
I wasn't to know as I through Gallarias Novas was the shop name but that was just the place.
They said that they had issued a new card that I hadn't received and even though they new I was abroad using my card they stopped it anyway.
When my new card did arrive after getting home I now know the reason was that they were making me have a con tactless card whcih I did nto request.

 Today I got a new phone and switched my sim and set up my banking apps inc Halifax and LloydÕs.
Halifax worked fine, usual 4 digit code and confirmation call came through and all set up in mins.

我应该如何抓取与原始内容相对应的单个摘要，并将它们放在dataframe中？

你一直在重写你的名单。替换

a = summarize(i, ratio=0.4, split = True)

使用

a.append(summarize(i, ratio=0.4, split = True))
