Abstract:

Social networking platforms disruptively change the way modern people communicate. More and more researches have focused on social networks from the social and technological perspectives. Link recommendation is a very important task. It not only can enhance internal linkage, but also will help improve the user experience. The existing link prediction algorithms in social-attribute network model do not comprehensively utilize the network structure information and attribute node information. This paper proposes several improved algorithms of link prediction based on local information, which combine effects of different types of common neighbors on social-attribute network model. These improved algorithms are given diverse treatment for the different influence from user common neighbor node and attribute common neighbor nodes. The test results in Google+ data set show that improved algorithm outperforms the algorithm, which does not consider the influence of common neighbor nodes on social-attribute model. After summarizing the different effects of diverse common neighbor nodes on link prediction, this paper provides corresponding suggestions on processing of different types of nodes.

Key words: link prediction, social attribute networks, node degrees, recommendation system, common neighbors
