I am getting this error: TypeError: '<' not supported between instances of 'str' and 'float'

Question

I have this table that in which I am comparing list of articles (Article_body) with 4 baseline articles using cosine similarity:

Article_body	articleScores1	articleScores2	articleScores3	articleScores4	articleScores5
a*****	0.6	0.2	0.7	0.9	0.2
a*****	0.3	0.8	0.1	0.5	0.1

I want to add a column that gives which column has the largest cosine similarity out of 5, condition it should be at least 0.5. If none of CosineSim(i)

Article_body	articleScores1	articleScores2	articleScores3	articleScores4	Most_similar_to
a*****	0.6	0.2	0.7	0.9	CosineSim4
a*****	0.3	0.8	0.1	0.5	CosineSim2
a******	0.1	0.2	0.3	0.4	False

I am using this code to achieve this:

cos_cols = [f"articleScores{i}" for i in range(1, 6)]    
def n_lar(text):
    if (df[cos_cols].idxmax(axis=1)) <0.5:
        return False
    
    else:
        df['Max'] = (df[cos_cols].idxmax(axis=1))

  
df['Most_similar_to'] = df.apply(n_lar)

However, I am getting this error:

TypeError: '<' not supported between instances of 'str' and 'float'

How can I resolve this?

Answer 1

(df.iloc[:, 1:-1]
 .astype('float')
 .apply(
     lambda x: ('CosineSim' + x.idxmax()[-1]) if x.max() >= 0.5 else False 
     , axis=1)
)

output:

0    CosineSim4
1    CosineSim2
2         False

make result to Most_similar_to column
