On Influence Maximization Problems in OSNs Considering Misinformation and Density Heterogeneity
Koari Ogawa, Norihiko Shinomiya, Masaaki Miyashita (Soka Univ.) CQ2025-78
Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, numerous studies have been conducted to curb the spread of misinformation on OSNs, which has become a societal problem. Previous research has compared solutions for maximising influence between models that account for misinformation and those that do not, simulating only two graph structures with differing overall densities to verify the effectiveness of explicitly treating misinformation. However, the difference in effectiveness when considering misinformation within dense and sparse regions coexisting within a single graph remains unclear. This study focuses on the characteristics of the graph structure to verify the effectiveness of considering misinformation under more realistic conditions.
