Abstract: This paper explored how one social network becomes inactive.We investigated the change of users’ activeness by analyzing the activeness period and Feeds inter-event time of users in a specific OSN.Our findings reveal that these users decrease their activity frequency or depart from the social network for various reasons and increase the interval time of Feeds,resulting in the decrease of information flow in velocity and diversity for the whole community.As a result,active users will feel the inactivity from their friends and increase the probability of being inactive as a feedback,which may be the underlying reason for the inactivity of OSN.Our simulation experiment shows that when 30% of users become inactive in generating Feeds,the whole community will be affected and collapse in a short time.

Key words: OSN,Activities analysis,Feeds behaviors,Inter-event time analysis
