This study tried to recognize the Chinese mood variations in different seasons and time periods via the big data on Internet. Participants were 1. 95 million active users of Sina Weibo. We downloaded their data of one week selected in each of the four seasons of one year. Then we used Text Mind to calculate the ratios of positive affect(PA) and negative affect(NA) words. Results are given as follows. 1) Integrated mood had two peaks at noon and 8 o 'clock in the evening. 2)Although PA in weekends was not different from that on the weekdays,NA in weekends was lower than that on weekdays. 3) In summer,both PA and NA were the highest. In autumn,both PA and NA were the lowest. 4) The two genders had similar mood variation trends,but females had more mood expressions than males and they were sentimental and susceptive.
