Analysis and Visualization of Japanese Law Networks Based on Granular Computing - Visual Law: Visualization System of Japanese Law

摘要

In order to grasp a perspective of the over 7,000 laws in Japan, and to find the relationships between law and laws, a method of creating a hierarchical network of laws using granular computing, is proposed. The proposed method analyze hierarchical networks by using an index of network science such as degree distribution and closeness centrality. Furthermore, it visualizes the hierarchical structure within the setting of granular computing. Using the JAVA-based language 'Prefuse,' a law network visualization system 'Visual Law' is implemented, and it is confirmed that users can easily analyze/understand the law network structure using our proposal.
