  Modeling the information dissemination process in social networks is a
challenging problem. Despite numerous attempts to address this issue, existing
studies often assume that user attitudes have only one opportunity to alter
during the information dissemination process. Additionally, these studies tend
to consider the transformation of user attitudes as solely influenced by a
single user, overlooking the dynamic and evolving nature of user attitudes and
the impact of the public opinion environment. In this paper, we propose a novel
model, UAPE, which considers the influence of the aforementioned factors on the
information dissemination process. Specifically, UAPE regards the user's
attitude towards the topic as dynamically changing, with the change jointly
affected by multiple users simultaneously. Furthermore, the joint influence of
multiple users can be considered as the impact of the public opinion
environment. Extensive experimental results demonstrate that the model achieves
an accuracy range of 91.62% to 94.01%, surpassing the performance of existing
research.
