Abstract: 【Purpose/significance】Forwarding behavior is an important way of information transmission on social media.Comments add?
ed by forwarders can reflect their emotional state and cognitive state.The research of forwarded comments in the context of natural di? saster emergencies is helpful for Emergency Management Department to know the trend of public emotion and cognition.【Method/pro? cess】When forwarded microblogs are forwarded again,a forwarding cascade will occur and different forwarding levels will be formed.In this paper,LIWC software was used to analyze comments added by forwarders from the perspective of emotion and cognition.We com? pared emotional scores and cognitive scores among different forwarding levels and emotional changes and cognitive changes in forward? ing comments.【Result/conclusion】The emotion and cognition of original microblogs related to natural disaster emergencies and for? warded comments are significantly different.Users tend to use words to express positive emotions,negative emotions,insight and cause in original microblogs.Words expressing positive emotions,insight and discrepancy were used more frequently and fluctuated more greatly across different forwarding levels.There was a significant positive correlation between the same type of emotion and cognition in the forwarded comments.【Innovation/limitation】This paper studies the characteristics of the content added by the forwarder,which can provide a new perspective of the decision-making and public opinion governance for Emergency Management Department after disas? ters.But we did not consider the influence of added comments on forwarding.We will compare the transmission effect of different for? warded microblogs later.
