Abstract
It is considered that ingenuity is required for dialogues about high-level radioactive waste disposal. However, information generated through current general dialogues is only uniformly provided, regardless of the characteristics of the participants, and it is considered that a mismatch occurs. In this study, by using text mining analysis based on two recorded dialogues between college students and the general public, we examined the characteristics of student dialogues about issues of high-level radioactive waste disposal. The results are as follows. Firstly, as a result of word advent, student dialogues have thoughts on the social aspects of the “object person,” “cases of developed countries,” and “publicity.” Secondly, they have thoughts about “nuclear power,” “understanding,” responsibility for waste generation in “Japan,” and from a broad range standpoint for “national people.” Thirdly, there is a result of a co-occurrence relation, for example “nuclear power” is connected to the words “thought” and “accident,” and there was a chain with other words. Also, “geological” and “disposal” are connected to words “employment” and “merits” which are indirectly affected by the advance of high-level radioactive waste disposal projects, and the words of “science course” regarding the degree of the participants’ knowledge. These are characteristics of student dialogues that could not be confirmed in a general dialogue. Therefore, we determined these three patterns within dialogue development of high-level radioactive waste disposal issues.
