A visualization system of relationships among papers based on the graph drawing problem

This study developed a support system that can retrieve papers by using the paper-relationship diagrams (PRDs) that express the relationships among papers. The system has the following functions: (1) users can see various relationships among papers by visualizing of PRDs; and (2) the visualization patterns can be changed dynamically by users own point of view. To implement the dynamic and safe visualization of the PRDs, the authors formalized user requirements for visualization as a set of constraints on the graph drawing problem, and developed an algorithm that visualizes the PRDs based on the graph drawing problem. By the implementation of the dynamic and safe visualization of the PRDs, users can see various relationships among papers by changing their own point of view.
