Abstract

Environmental issues include various elements. The complex relationship between environmental information should be illustrated and systematized to solve environmental issues. In this study, the appearance frequency of environmental terminology was analyzed on the media such as Grants-in-Aid for Scientific Research, newspaper, academic paper, Minutes, National Diet Library, and the White Paper. The following environmental terms were studied: “Global warming”, “biomass”, “dioxin”, “asbestos”, “ozone layer”, “environmental hormone”, “carbon dioxide”, “carbon trading”, “renewable energy”, “recycling”, “solar power” and “greenhouse gas”. Graphical modeling was employed to analyze environmental information transmission. Based on the similarity level of the graphical models, the environmental terms were classified into the 3 groups: “Global warming”, “biomass” and “dioxin” groups. It is suggested that “dioxin” group terms are media-related; “biomass” group terms are expert-related; and “Global warming” group terms are government-related. It was clarified that each group has similarity concerning the feature of environmental issues and environmental information transmission structure. In conclusion, some part of environmental information transmission structure was illustrated based on the structure analysis by graphical modeling.
