  In recent years, the proliferation of disinformation has become an issue
against the backdrop of the spread of social media. In this study, we focus on
socialbots, one of the causes of this problem, and analyze several domestic
cases to clarify the actual activities and influence of socialbots. As a result
of this analysis, we found that the influence of socialbots is greater in Japan
than in the U.S. presidential election of 2016, which is a representative case
of socialbot influence, and that socialbots retweeted by humans are not
significantly different from human accounts. In addition, socialbot accounts
retweeted by humans are not significantly different from human accounts. This
paper also discusses specific methods and perspectives for further analysis and
research on the influence of socialbots.
