Dissemination of the Spirit of Public Security Models in the Age of Melting Media

Public security heroic model culture is a political-cultural phenomenon with Chinese characteristics formed by public security organs in the process of selecting, recognizing, publicizing, and appeasing heroic models. This paper researches the culture of public security heroic models and proposes a model for disseminating the spirit of public security heroic models through social role perception, called RAIN. The RAIN model unified the two complementary tasks of the information dissemination process and the social roles of users. The model maps the dissemination parameters between users and those between social roles, reducing the number of parameters. The parameters are estimated using a Gibbs sampling-based learning algorithm. At the same time, a continuous influence maximization algorithm is proposed under the independent cascade propagation model, which can calculate the incremental values in each direction by the gradient descent method and get the optimal solution of the objective function value. The communication status of the spirit of public security heroism is analyzed, and the total word frequency of all the communicated high-frequency words is 8350, which is lower than 10,000 and is at the lower-middle communication level. The total communication power value and total influence value of the spirit of public security heroes are 1042 and 4701, respectively, and the number of high communication power and high influence content is only 22 and 21, so there are obvious deficiencies in the work of communication field. This paper takes the shortcomings as a starting point and proposes a communication optimization strategy accordingly.
