We aim to support citizen-participatory discussions about public collaboration usingevidence data. There is a suitable dataset on volunteer recruitment collected by Boramimi, a nonprofit organization. Therefore, we analyzed this dataset in order to use the analysis result as an evidence of the discussion. This analysis is based on TF-IDF and information gain in order to use the data in a discussion experiment. We developed a web application for visualizing the analysis results in order to use the data as evidences of opinions in citizen-participatory discussions.
