问题
I am trying to do a sentiment analysis from a csv file where each row has a sentence.
Reprex:
print(your_list)
[['Patience and Kindness and I know they truly love and care for animals, my dog also enjoys the events like seeing Santa and the Easter Bunny'], ['They are so sweet to my pets and try to fit them into the schedule when needed'], ['they call and check on our pet a day or 2 after visit make sure we fully understand treatment before we leave'], ['every member of the staff understands how our pets are our family; we never feel rushed and always have or questions answered, and are given reassurance if and when needed; they are compassionate and kind, respectful and very caring'], ['They made it a very peaceful experience when we had to put our pug to sleep '], ['They interact with my dogs and you can see the care they have for them.'], ['they make every effort to accomodate us']
from vaderSentiment.vaderSentiment import SentimentIntensityAnalyzer
import csv
with open('Before.csv', "r", errors='ignore') as f:
reader = csv.reader(f)
your_list = list(reader)
print(your_list)
analyser = SentimentIntensityAnalyzer()
def print_sentiment_scores(sentence):
snt = analyser.polarity_scores(sentence)
print("{:-<40} {}".format(sentence, str(snt)))
print_sentiment_scores(your_list)
However, I receive the below error:
analyser = SentimentIntensityAnalyzer()
def print_sentiment_scores(sentence):
snt = analyser.polarity_scores(sentence)
print("{:-<40} {}".format(sentence, str(snt)))
print_sentiment_scores(your_list)
Traceback (most recent call last):
File "<ipython-input-24-a7a32425d261>", line 8, in <module>
print_sentiment_scores(your_list)
File "<ipython-input-24-a7a32425d261>", line 4, in print_sentiment_scores
snt = analyser.polarity_scores(sentence)
File "C:\Users\abc\AppData\Local\Continuum\anaconda3\lib\site-packages\vaderSentiment\vaderSentiment.py", line 248, in polarity_scores
text_token_list = text.split()
AttributeError: 'list' object has no attribute 'split'
.split(" ") function on your_list is not helping
回答1:
Vader's 'polarity_scores(sentence)' takes a string parameter, not a list.
Your code should be:
analyser = SentimentIntensityAnalyzer()
def print_sentiment_scores(alist):
for aSentence in alist:
aSnt = analyser.polarity_scores(aSentence[0])
print(str(aSnt))
print_sentiment_scores(your_list)
So I finally got this to work with the following code and csv:
#!/usr/bin/python3
import csv
from vaderSentiment.vaderSentiment import SentimentIntensityAnalyzer
with open('Before.csv', "r", errors='ignore') as f:
reader = csv.reader(f)
your_list = list(reader)
analyser = SentimentIntensityAnalyzer()
def print_sentiment_scores(alist):
for aSentence in alist:
aSnt = analyser.polarity_scores(aSentence[0])
print(str(aSnt))
print_sentiment_scores(your_list)
Associated .csv's contents:
['Patience and Kindness and I know they truly love and care for
animals, my dog also enjoys the events like seeing Santa and the Easter
Bunny'], ['They are so sweet to my pets and try to fit them into the
schedule when needed'], ['they call and check on our pet a day or 2 after
visit make sure we fully understand treatment before we leave'], ['every
member of the staff understands how our pets are our family; we never feel
rushed and always have or questions answered, and are given reassurance if
and when needed; they are compassionate and kind, respectful and very
caring']
Output:
If you want the output strings to be formatted, please do some research on string-formatting. Or post another question on SO, if you cannot find an answer.
回答2:
SentimentIntensityAnalyzer.polarity_scores(text)
takes as argument text/str. you pass list of lists. Probably you want to pass the whole content of the file as single text or pass each sentence separately, but not list of lists.
回答3:
The problem lies in the call to the function 'print_sentiment_scores'. The parameter passed is a list. Based on your requirement, I think you can pass the elements of the list to get the split. Split() works on string type as per the documentation here
