| Summary: | The rumor spreading in social networks could be considered as “infection of the mind”
among people. In human society, each person’s mind may be affected by people around
him/her, especially by those with stronger influences. In this dissertation we attempt
to analyze the effects of herd behaviors on opinion formation in human society when
we tend to clean up the rumor spreading. The SIR model is adopted in simulating the
spread and cleaning up of the rumor. To evaluate the effects of herd behaviors, we test
on different cases with the classic SIR model and SIR model with herd behavior
respectively. By comparing between different cases, we could figure out the factors
that obstruct and promote the rumor cleaning process respectively, and the roles that
are well-known and influential individuals may play in rumor cleaning process. |
