In this paper, we propose a multi-perspective analysis approach for discussion, integrating assessments of discussion structure and quality. As a demonstration experiment, we conducted an online discussion (OD) on the issue of removed soils in Fukushima Prefecture and gathered discussion data at Tokyo and Osaka. To compare the discussions in Tokyo and Osaka, the analysis was conducted using two methods: 1) Discussion structure analysis (IBIS), 2) discussion quality index (DQI). The IBIS results revealed a higher frequency of discussions on ‘issues’ in OD-Osaka compared to OD-Tokyo, while discussions on problem-solving ‘ideas’ were more prevalent in OD-Tokyo. In the DQI results, both OD-Tokyo and OD-Osaka consistently prioritized ‘risk and cost’, with less emphasis on ‘burden sharing’ and ‘prioritizing the residents of Fukushima’. Comparing the two sets of results, OD-Tokyo exhibited a higher frequency of ‘prioritizing risks and costs’ and ‘burden sharing’, whereas OD-Osaka showed a higher frequency of ‘prioritizing the residents of Fukushima’. Differences in discussion structure and quality among residents from different regions were evident through IBIS and DQI. The primary outcome revealed successful visualization of discussion data characteristics that couldn't be captured by a single evaluation scale.
