Based on the personal properties and the status in social network, various behaviors are done by users, and the friendships are developed at the same time. As the frequent interaction is one the key character of friendship, it is proposed that the friends interaction behaviors are similar to each other, and the interaction mechanism is of reciprocity. Based on the time series analysis of user behaviors, interaction behaviors similarity computing model is proposed. Using the blog history snapshot data, the publishing, sharing, commenting and wall posting behaviors are evaluated, and then the similarity computing models are tested.
