#导入数据，APP的评论
comments = pd.read_csv('googleplaystore_user_reviews.csv')

#共865个APP，3万7条评论

#comments['App'].value_counts()
#好评，中评，差评各多少个
comments['Sentiment'].value_counts()

#sns.jointplot(comments['Sentiment_Polarity'],comments['Sentiment_Subjectivity'],kind='kde')
#取出评论具体分析下
review = comments['Translated_Review']
导入wordcloud 做词云看下高频词
final = " ".join(review for review in comments['Translated_Review'])
from wordcloud import WordCloud
word_pic = WordCloud(font_path = r'C:\Windows\Fonts\simkai.ttf',width = 800,height = 400).generate(final)
fig = plt.figure(figsize=(15,9))
plt.imshow(word_pic)
#去掉坐标轴
plt.axis('off')
#保存图片到相应文件夹
plt.savefig(r'7.jpg',dpi=800)

出现最多的是 game,good,app，time, great,make,work,even等
好像没看出什么有意思的，我们再把好评和差评分开做个词云看看什么结果
final_pos = " ".join(review for review in comments[comments['Sentiment']=='Positive']['Translated_Review'])
#打印一段看下用户的好评
final_pos[0:1000]

"No recipe book Unable recipe book. Waste time It needs internet time n ask calls information Faltu plz waste ur time Crap Doesn't work Boring. I thought actually just texts that's it. Too poor old texts.... No recipe book Unable recipe book. Waste time It needs internet time n ask calls information Faltu plz waste ur time Crap Doesn't work Boring. I thought actually just texts that's it. Too poor old texts.... Not bad, price little bit expensive Horrible ID verification There is nothing missing ~ !!! Refund takes long.. 3 days still received money.. crazy I am trying to update every time but I do not stall. It's still difficult to search, and I'm tired of seeing categories by category. The benefits are getting less and less. Icon name is strange after updating It has been slowed down since the last update. It's hard for me to pay for the product ... I'll give up when I'm alive. If a network error occurs, the app should save the state and try again, or try to re-point the next time, but"

对比下两张图，可以看到
跟好评有关的情绪高频词有great,good,love,better,easy等
跟差评有关情绪的词有ad,terrible,bad,worst,suck,useless等
对比category和sentiment
从另一张表导入APP的category

#分析下不同Catgory的评论情感是否有不同
a= Review['App'].groupby([Review['Category'],Review['Sentiment']]).count()
b =pd.DataFrame(a)
b=b.unstack()
b.head()
image.png
b=b['App']
b.sort('Positive',inplace=True)
C:\Users\renhl1\Anaconda3\lib\site-packages\ipykernel\__main__.py:2: FutureWarning: sort(columns=....) is deprecated, use sort_values(by=.....)
from ipykernel import kernelapp as app
fig = plt.figure(figsize=(15,9))
sns.barplot(x=b.index,y=b['Positive'],label='Positive',color='green',alpha=0.8)
sns.barplot(x=b.index,y=b['Neutral'],bottom=b['Positive'],label='Neutral',color='yellow',alpha=0.8)
sns.barplot(x=b.index,y=b['Negative'],bottom=b['Positive']+b['Neutral'],label='Negative',color='red',alpha=0.8)
plt.xticks(rotation=90)
plt.xlabel('category')
plt.ylabel('App qty')
plt.title('App qty by category with different sentiment')
plt.legend()
image.png
看各category中好评，中评，差评的数量多少，
不过这样不好对比，我们再转化成APP占比进行对比
#计算Ratio
b['Pos_ratio']=b['Positive']/(b['Negative']+b['Neutral']+b['Positive'])
b['Neu_ratio']=b['Neutral']/(b['Negative']+b['Neutral']+b['Positive'])
b['Neg_ratio']=b['Negative']/(b['Negative']+b['Neutral']+b['Positive'])
fig = plt.figure(figsize=(15,9))
sns.barplot(x=b.index,y=b['Pos_ratio'],label='Pos_ratio',color='green',alpha=0.7)
sns.barplot(x=b.index,y=b['Neu_ratio'],bottom=b['Pos_ratio'],label='Neu_ratio',color='yellow',alpha=0.7)
sns.barplot(x=b.index,y=b['Neg_ratio'],bottom=b['Pos_ratio']+b['Neu_ratio'],label='Neg_ratio',color='red',alpha=0.7)
plt.xticks(rotation=90)
plt.xlabel('category')
plt.ylabel('App qty ratio')
plt.title('App qty ratio by category with different sentiment')
plt.legend(loc='upper right',fancybox=True,facecolor='blue',shadow=True).get_frame().set_facecolor('C0')
plt.show()

可以看到好评较高的category有tools,education,auto and vehicles,commics
以上就是用户评论的初步分析，谢谢！
