Development of a spatiotemporal situation analysis system based on graph structuralization

Despite the development of information technology and the pervasiveness of situation-specific data, such as incident and situation reports, we lack methods for analyzing situational data. In this study, we propose a new system for analyzing the structure of a situation that integrates graph-structuralization, a spatiotemporal analysis system, and a database of the relation between behaviors and three-dimensional objects. This new integrated situational analysis system allows the use of geographic information. For instance, it uses cluster analysis to extract typical situations and then uses this information to create frequency maps. To evaluate the effectiveness of the integrated analysis system, we analyzed the data of over 200 household incidents.
