Abstract:

Heterogeneous network is a complex information network with many types of nodes and edges, so the visuali-
zation of heterogeneous network usually involves effective processing and visualization technology of heterogeneous information. Traditional network visualization methods are confusing in layout effect and difficult to reflect heterogeneous information for heterogeneous network visualization. A multidimensional visualization method of heterogeneous network based on dynamic projection embedding is proposed. This method starts with the representation learning of heterogeneous network, and proposes the dynamic projection embedding algorithm to learn the node representation. On this basis, a multidimensional visualization method is proposed to mine potential semantic information, which maps heterogeneous network node to different relational spaces according to different attributes of node. The experimental results show that the proposedmethod not only improves the MRR of heterogeneous network representation learning by 10%, but also visualizes the heterogeneous network from multiple dimensions, effectively displaying and mining the heterogeneous information and potential semantic information in the network.
