AttributeError: 'WordList' 对象没有属性 'split'

Question

在对“脚本”列进行标记后，我正在尝试应用 Lemmatization。但我得到一个属性错误。我尝试了不同的方法

这是我的“脚本”专栏：

df_toklem["script"][0:5]
---------------------------------------------------------------------------
type(df_toklem["script"])

输出：

id
1    [ext, street, day, ups, man, big, pot, belly, ...
2    [credits, still, life, tableaus, lawford, n, h...
3    [fade, ext, convent, day, whispering, nuns, pr...
4    [fade, int, c, hercules, turbo, prop, night, e...
5    [open, theme, jaws, plane, busts, clouds, like...
Name: script, dtype: object
---------------------------------------------------------------------------
pandas.core.series.Series

以及我尝试应用词形还原的代码：

from textblob import Word
nltk.download("wordnet")
df_toklem["script"].apply(lambda x: " ".join([Word(word).lemmatize() for word in x.split()]))

错误：

[nltk_data]   Package wordnet is already up-to-date!

AttributeError: 'WordList' object has no attribute 'split'

我尝试了不同的方法，但遗憾的是找不到有效的解决方案。感谢您的宝贵时间。

您尝试执行的操作不起作用，因为您将字符串函数（拆分）应用于单词列表。 我会尝试改用 nltk，并使用我的标记化数据创建一个新的 pandas 列：

import nltk
df_toklem['tokenized'] = df_toklem.apply(lambda row: nltk.word_tokenize(row['script']))
