Google to analyze the emotion of every piece of comment to obtain numbers of sentences with negative, positive, neutral attitude. Collected them into the excel to calculate the numeral proportion of comments with counting sentence's sentiment and then visualize it.

The Chinese data that we collected may have language issues because sometime Chinese use positive satiric comments to describe negative feeling. Since we used Google Translate to change the language of the comments some of these satiric comments could be calculated as positive.
