Large Temporal Relational Network Visualization Technology Research

The social relations network is a hot issue in the field of information technology. Since social relations network has a significant time features, the studying of temporal relations network is of great significance. So far the visualization of large-scale temporal relations network is an important issue to be resolved in effect. The network not only has many nodes, but the relationships between these nodes will change over time. This article addresses the problem by proposing time-based force to layout nodes, and introduce optimize process into the layout to solve the problem of large-scale temporal relations network visualization.This paper studies visualization technology and algorithms about the large-scale network of relationships. Hybrid layout algorithm is often used. However, the process of region segmentation easily leads to the failure of the hybrid layout algorithm. The article analyzes the optimize objectives and constraints in the process of region segmentation and proposes nonlinear constrained optimization model to optimize regional utilization, success rate of the segmentation as well as the aesthetics of the layout comprehensively. On this basis, how to reflect the temporal features of the relations network in hybrid layout algorithm is also a crucial need to address in this issue. This paper analyzes the principle of the force directed algorithm, studies the time factor, which is converted to virtual force to perform the strength of relationship and mapped to the force directed algorithm. So that, the layout can reflects temporal features. The results show that the proposed algorithm displays the temporal features of relations network. Additionally, the application of nonlinear constrained optimization model improves the success rate of the segmentation and the aesthetics of layout.
