Outline of Final Research Achievements

How the radiation health information is spread regionally and temporally?
The purpose of this study is to clarify whether there are any relation between radiation-related articles and recognition that citizen has for radiation. We used newspapers and Twitter data collected during a year from March 2011. We try the Sentiment analysis, regional analysis and Co-occurrence network analysis.
