AttributeError: 'tuple' object has no attribute 'lower' sentiword

Question

I try this code to calculate the sentiment using sentiword, I tried tokenization and pos tagging it works but when I tried this I get error message

print("Array..............\n\n")
tagged=np.array(df['tagged_texts'])
print(tagged)
pos=neg=obj=count=0
for word, tag in tagged:
    ss_set = None
    if 'NN' in tag and swn.senti_synsets(word):
        ss_set = list(swn.senti_synsets(word))[0]
    elif 'VB' in tag and swn.senti_synsets(word):
        ss_set = list(swn.senti_synsets(word))[0]
    elif 'JJ' in tag and swn.senti_synsets(word):
         ss_set = list(swn.senti_synsets(word))[0]
    elif 'RB' in tag and swn.senti_synsets(word):
         ss_set = list(swn.senti_synsets(word))[0]
    if ss_set:
        pos=pos+synset.pos_score()
        neg=neg+synset.neg_score()
        obj=obj+synset.obj_score()
        count+=1

I get error

    Array..............

Can anyone help me to understand where this code got wrong? thank you

Answer 1

tagged begins as a list of pairs of tuples. So, word and tag are both tuples. e.g. the first values for word and tag will be

word : ('no', 'DT') 
tag : ('coment', 'NN')

Perhaps, try:

temp = []
    for x in tagged: 
        for y in x: 
            temp.append(y) 
tagged = temp

before running the loop - assuming you want to iterate over the tuples in your main loop.
