Abstract:

To explore the structural features of the two types of recommendation networks—social and living application network and system application network, through social network analysis and empirical analysis, the structure of the two recommendation networks are calculated, analyzed and compared The results show that the density of two networks are relatively low, but social and living application network is lower; the scale of the biggest association diagram of two networks are small, but system application network is smaller; nodes of them have significant differences in the aspects of point centrality, middle centrality and closeness centrality
