Question

我试图了解如何根据获得的分数构建甜甜圈图或饼图。以下是我的代码

from nltk.sentiment.vader import SentimentIntensityAnalyzer

paragraph = "I loved the movie"          
sid = SentimentIntensityAnalyzer()
ss = sid.polarity_scores(paragraph)
print(ss)
if ss["compound"] >= 0.5:
    print("positive")
elif ss["compound"] <= -0.5:
    print("negative")
else:
    print("neutral")

# myresults 
{'neg': 0.033, 'neu': 0.834, 'pos': 0.132, 'compound': 0.9936}
positive

如何使用复合分数将所有这些值计算为百分比？现在，我只能给它一个正面，中性或负面的标签，但我希望根据复合得分来分解所有值。在此示例中，积极得分应为99％，而不是61.2％中立，0％消极和38.8％积极

Answer 1

您有ss = {'neg': 0.033, 'neu': 0.834, 'pos': 0.132, 'compound': 0.9936}，并且您想使用neg，neu和pos的值生成饼图。如果我错了请纠正我。

尝试一下

labels = ['negative', 'neutral', 'positive']
sizes  = [ss['neg'], ss['neu'], ss['pos']]
plt.pie(sizes, labels=labels, autopct='%1.1f%%') # autopct='%1.1f%%' gives you percentages printed in every slice.
plt.axis('equal')  # Ensures that pie is drawn as a circle.
plt.show()
