Introduction:-
With the vigorous development of various Internet technologies, more and more electronic
business platform, social platforms, news platforms, film and television platforms have
emerged. People only need to browse other people’s comments on commodities or movies
online as a reference to filter out the commodities they want to buy or the movies they want to

and satisfaction. For instance, news platforms want to analyze the opinions and sentiments of
netizens, business platform platforms hope to get user reviews to improve products .With so
many demands, sentiment analysis has become a very active field.
