Abstract:

Concerning dynamic social network link prediction, the paper proposed an improved DynamicTriad model. The dynamic triadic closure structure was the carrier, and three vertices formd a basic network unit. Combined with the network homophily and similarity index, the dynamic network was represented dynamically and each node was represented in different time slices, as to realize the dynamic individual behavior prediction of social network. Moreover, the t+1 time embedding vector was used to validate t time prediction effect. Experiments show that the improved model represents the relationship between nodes dynamically, and the effect of link prediction is better than the traditional algorithms. Besides, the proposed method supports the modeling and analysis of dynamic social network.

Key words: social network, dynamic network, link prediction
