Analysis and Modeling of Information Dissemination Process: A Study Based on LDA Topic Model and Fuzzy Comprehensive Evaluation

This paper, on the basis of collecting topic-related data, constructs LDA topic model, fuzzy comprehensive evaluation model of hierarchical analysis method, firstly to determine the topic type; secondly to quantitatively portray the topic dissemination process; finally to quantify the information dissemination index and construct a comprehensive evaluation system. Then we use Python program to clean the collected data, get the data of the influencing factors related to the topic dissemination process, apply Matlab software to solve the model parameters, fit the information dissemination law graph, and finally get the topic dissemination process change law over time.
