I am working on a project with tf-idf, I have a column (df['liststring']) in my dataframe that contains the preprocessed text (without punctuation, stop words, etc.) from my various documents.
I ran the following code, and I got the top 10 words with the highest tf-idf values but I would like to see their scores as well.
from sklearn.feature_extraction.text import TfidfVectorizer
tfidf = TfidfVectorizer()
X_tfidf = tfidf.fit_transform(df['liststring']).toarray()
vocab = tfidf.vocabulary_
reverse_vocab = {v:k for k,v in vocab.items()}
feature_names = tfidf.get_feature_names()
df_tfidf = pd.DataFrame(X_tfidf, columns = feature_names)
idx = X_tfidf.argsort(axis=1)
tfidf_max10 = idx[:,-10:]
df_tfidf['top10'] = [[reverse_vocab.get(item) for item in row] for row in tfidf_max10 ]
df_tfidf['top10']
