Abstract:

Arc-directed weighted temporal networks can more accurately describe the changing of the interactive association relationship of the tendency selection and intensity of tendency between nodes in the time-evolving. To identify key nodes in arc-directed weighted temporal networks, a method for assessing node importance based on multi-attribute fusion is proposed. Firstly, to expand and mine the temporal evolution of diverse information sources in networks, multi-attribute features of the network are aggregated to construct a comprehensive importance matrix column, which can represent the interactive association relationship of the tendency selection and intensity of tendency between the intra-layer nodes. Then, the similarity of transmission capabilities between node layers is defined to characterize the similarity between network layers. Finally, the multi-attribute fusion super-adjacency matrix of the arc-directed weighted temporal network is constructed by integrating the intra-layer interaction relationship and inter-layer association relationship between the nodes. The feature vector column centrality method is used to rank the importance of nodes in the arc-directed weighted temporal network, comprehensively characterizing the evolution of the node importance order structure in the arc-directed weighted temporal network. Empirical data simulation shows that the proposed model has a good representation of the key features of the arc-directed weighted temporal network, and the resulting node order structure has better recognition accuracy than other models, and the transmission capacity of the top ranked nodes is better than other models. The proposed model can provide ideas for accurately describing the complex interactive association relationships between nodes in temporal networks, and can provide powerful tools for a deeper understanding of network structure and its evolution.

Key words: directed weighted temporal network, super-adjacency temporal matrix column, multi-attribute fusion, order structure evolution and recognition
