Thus, decision of social and public opinions, and polarity about social happenings, political issues, government policies and decision, or commercial products is very important to the government, company, and a person. But, SNS are basically making newly-coined words and emoticons. Especially, emoticons are made by a person or companies. Newly-coined words are mostly made by communities.

The polarity and weight would be calculated for emotional classification. The proposed emotional classification equation adds up the weights among the same polarity(positive or negative) and sums the negative weight value with the positive weight values. The polarity summation result is recorded in the variable. If the polarity summation result is more than threshold value, the twit message is decided as positive. If it is less than threshold value, it is decided as negative and the other values are decided as neutral. The accuracy of social big data analysis is improved by quantifying and analyzing emoticons and new-coined words.
